SUBMERSIBLE CENTRIFUGAL PUMPS (ESP)

The Alnas pumps are designed using sectional principle and consist of upper section (with fishing head for fastening pump to tubing string), midsections, intake module, gas separator, and check valve and bleeder valve.

Check valves have high tightness permitting to conduct coil tubing pressure/leak test. Check valves design may be poppet valve type or ball type (option by request).

Intake module may be provided with pump section as a whole to lower a number of connections. In that case, the pump unit (complete) has a lower stage provided with perforations for liquid intake.

Intake submersible wire filter can also be used for submersible pumps to take formation fluid and separate solid particles with cross-section of 0.1 or 0.2 mm. For detailed filter data, see Page 21.

At high gas content in formation fluid, complete pump may include a gas separator. When PPFA is included, gas separator is made w/o intake openings.

Pump section length is varied to provide optimal pump selection for any wellbore length. Intermediate radial bearings are installed along the section (see fig). Reliable and long pump operation under various operating conditions is provided by optimum distance between radial bearings.

DOUBLE-SEAT DESIGN PUMPS

Application of ESP with "double-seat design" pump stages allows pump operation at arduous conditions with high solids content. This stage design provides significantly enhanced mean-time-between-failures for the ESP pumps.

High service life of "double-seat design" pump is conditioned by considerably lower friction loading per unit area of impellers The stages are extended in both sides, which allows to:

• Reduce vibration (impeller stability enhanced due to multiple increased impeller fit length on a shaft)• Hidden shaft providing its protection from formation fluid hydroabrasive effect• Practically eliminate wedge key cutting and stage to shaft turning (impeller key slot length is multiply increased to minimize key

load).Special materials used for operating in conditions of hydroabrasive wear – pump stages are made of Ni-resist or modified (non-corrosion resistant) cast-iron of enhanced wear resistance.

Complete set of tools and accessories for in-field mounting & installation are available for order. All necessary spare parts can be supplied in any amount required.

PUMPS WITHOUT AXIAL BEARING SHAFT

These pumps features are as follows:

• Axle loading transmitted by pump shaft is sustained by reinforced seal section thrust bearing assembly• Mounting & installation is simplified as compared to competitors• Section hydraulic efficiency is enhanced due to pump stage quantity increased• Pump shaft cantilevers are reduced• Section hydraulic efficiency is enhanced due to shaft axial bearing transferred from pump section to seal section cave and in-

creased number of pump stages in pump sections

Pumps without shaft axial bearing have the following advantages:

• Pump operating elements are of Ni-resist iron or Ni-resist type austenitic cold pig iron with hardness of HB 190 to 240 (option by request)

• Radial bearings are manufactured using hard alloys• Lower pump vibration level and radial bearings loading due to reduced shaft cantilevers

PUMPS WITH PACKET STAGE ASSEMBLY

Alnas offers pumps with packet stage assembly, enhanced corrosion and wear resistance, designed for reservoir fluid production in diffi-cult operating conditions.

This pump type features are as follows:

• Pump sections without shaft axial bearing (transmitted shaft axle loading is sustained by thrust bearing).• Packet stage assembling provides axial and radial support for every packet of stages• Operating elements of single pad design w/ extended hub• Impeller hubs contact each other and transfer axle loading to radial-axial support installed in stage packet lower part• Shaft overhang is reduced relative to radial bearing• Due to reduced base overall dimensions, the protective ribs for cable extension are removed from the base to the head

The benefits of pumps with packet stage assembly are as follows:

• Pump operating elements are of Ni-resist type austenitic cold pig iron, with hardness of HB 190 to 240, and high corrosion resistant• Radial bearings are manufactured using hard alloys• Low impeller washers wear• Due to reduced shaft cantilever, pump unit total vibration level is reduced• Protective ribs located in the head allow for cable protection from the very top of the section.

New 0215, 0615 and 2215 series pumps are of the newest high-efficiency submersible centrifugal corrosion and wear resistant Alnas pumps line. There are new stages applied in pump designs allowing to increase unit life-time and to reduce produced oil volume cost unit at rated delivery with maximum efficiency and minimum power inputs.

ABOUT ALNASGas separators

ABOUT ALNASGas separators

GAS SEPARATORS, DISPENSERS

Gas separators, dispensers, and gas separator-dispensers are designed to ensure electrical centrifugal pump steady operation when pumping out formation fluid having high gas void fraction.

Gas separator is essential when oil production well has high dissolved gas content. For installation at pump inlet instead of intake module or after intake module in a gas separator model w/o intake screen. Alnas produces and delivers effective gas separators for all types of pumps and for various operating conditions.

Gas separator operating principle is based on using centrifugal force for free gas disposal. The gas is withdrawn into annular space to eliminate gas slug generation, ensuring Alnas ESP unit steady operation and enhancing mean-time-between-failures.

Dispenser is designed for refining entrapped gas in formation fluid, preparation of homogeneous gas-liquid mixture and feeding it to submersible centrifugal pump inlet. When gas-liquid mixture flow passes through dispenser, its homogeneity and entrapped gas breakage degree rise, enhancing centrifugal pump operation: lower vibration and stream pulsation in tubing, providing operation with efficiency required.

Gas separator-dispensers are installed at pump inlet in lieu of gas separator/ dispenser in ultrahigh GOR wells, where separator or dispenser application cannot ensure electrical centrifugal pump steady operation.

APPLICATION CONDITIONS

Gas separators, dispensers, and gas separator-dispensers (the "products") are designed for applications with formation fluid parameters as follows.

Max free gas at inlet (%):- Gas separators – 55 - Dispensers – 30–40- Gas separator-dispensers – 75Delivered liquid temperature (°С) – 150pH value – 5.0–8.5Max solids concentration in formation fluid (g/l) – 1.0Mohs hardness number of particles, max – 7Max H2S concentration (g/l) – 1.25Max produced water content (%) – 99Max density of liquid (kg/m3) – 1,400Single-phase liquid kinematic viscosity at which pump operation is provided without head and efficiency changing (mm2/sec) – 1

DESIGN FEATURES

Radial bearing friction pairs are made of hard alloy. Axial shaft bearing is made of ceramics. End pieces and protective cases are made of corrosion resistant steel to enhance hydroabrasive wear resistance. Flow sections are made of corrosion and wear resistant steel and Ni-resist type iron with hardness of HB 190 to 240. There may be a base design version with intake shortened openings w/o screen.

All units are supplied in corrosion- and wear-resistant types.

PPFA SUBMERSIBLE WIRE FILTER

Purpose and Principle of Operation

PPF submersible wire filter is designed to protect ESP from ingress of solids, formation fluid propping agent particles with cross-section over 0.1 mm (particles content up to 3 g/l). Formation fluid is filtered when flowing through the filtering element slotted screens. Gravity and vibration effect results in filter self-cleaning during operation. Filtration degree is defined by the slot size. Bearing assembly uses bushings of hard alloy. At both sides of movable bush on the shaft, the forced cooling device for a bearing pair is provided to eliminate overheating of the bearing. PPF submersible wire filter can be equipped with one or several sections selected depending on pump throughput. PPF is to be installed between seal section and pump lower section or between seal section and gas separator (w/o intake module).

Basic benefits:

• Using as ESP unit component• Repairability• Filtration degree is 0.1 mm or 0.2 mm• High strength and durability of the filter• Clog-proof, self-cleaning filtering elements• Radial bearing of hard alloy use• Bearing forced cooling

MOBILE PUMPING UNIT WITH ELECTRIC DRIVE PNSHME (91-2.5-40/116-2.5-40)

Mobile Pumping Unit is intended for test short-term service of reactivated or new wells to determine their productivity and other characteristics that help to choose a size and make of a stationary pumping unit for well operation.

If required, Mobile Pumping Unit may be used for continued well operation.

Transport position Working position

Mobile Pumping Unit produced by Izhneftemash has several advantages over foreign analogues:

• Hinge-jointed unit consisting of a walking beam, a Samson post and a frame is very easy in design, that’s why Mobile Pumping Unit may be quickly transformed from transport to working position and conversely with any crane truck

• A commercial semi-trailer and a beam-balanced pumping unit involving unified components are included in Mobile Pumping Unit. This significantly reduces the cost of a unit, increases its reliability and serviceability

• Automatic descending and lifting of base plates when transforming Mobile Pumping Unit from transport to working position and conversely with a general-purpose crane truck having a load capacity of 10 tons and more

DOUBLE-STAGE (DIFFERENTIAL) PUMP 30-225/150 RHBM 12-4-2-2

Consists of:

• Barrel with standing valve. There is a hollow rod guide on the top of barrel for sealing upper chamber (high-pressure stage)

• Plunger with traveling valve and hollow polished rod with additional valve on the top of a rod. Rod is connected with plunger with the help of adapter with side holes connecting internal hollow of a plunger and a rod with upper cham-ber which is the space between rod and barrel

• Inner hollows of a plunger with traveling valve, rod with valve and upper cham-ber create high pressure stage. Under-plunger space (lower chamber) is a low pressure stage.

Pump operation:

When plunger moves upwards, both plunger valves are closed; standing valve is opened, and well fluid flows in a lower chamber (low pressure stage)

When plunger moves downwards, upper plunger valve remains closed and standing valve is closing. Fluid flows in upper chamber through open lower plunger valve

With following upstroke, lower plunger valve is closed by fluid pressure, which is achieved by diminishing upper chamber space

When pressure in upper chamber equals the fluid column pressure in tubing string, upper plunger valve opens and fluid flows in tubing string. At the same time, fluid flows through opened standing valve into lower chamber

Thus, lower chamber is filled and released without fluid column pressure in tubing. It creates favorable conditions for pumping gassed well fluid.

TUBING PUMPS OF SPECIAL DESIGN

Pumps ТНМ-Т with diameters 32, 44, 57 and 70 mm with non-removable standing valve.

Standing valve is set in the bottom of pump instead of seating nipple; fishing tool is not available. Diameter of standing valve (seat and ball) for pumps with diameters 32,44,57 mm is oversized, providing more stable pump operation (free of valve sticking, oc-curred because of paraffin deposits). Pumps are used together with drain valve (SKOK type or other) placed above pump to drain fluid from tubing when pump is pulled out.

The following makes are developed on the base of THM-T pumps:

• pumps with non-removable standing valve, barrel with side drain hole and long plunger (10 feet) (ТHМ – Т 11-10-2-2). Plunger is fitted so that side hole of barrel is constantly covered by plunger; plunger stroke is 3 m. When plunger is in its lower position (at its stop) and when it is pulled out from barrel, drain hole is opened to ensure drain of fluid from tubing both when plunger is pulled out on rods and when rods and plunger components are parted or unscrewed; direct flushing at well completion is provided as well.

• pumps with side standing valve (BVK). The plant produces BVK valves for THM-T tubing pumps with diameters of 32 and 44 mm. BVK valve is delivered optionally and set under barrel instead of bottom part of a pump. In pumps equipped with BVK valves dead space is almost zero in a barrel, when a plunger is in its lower position. This allows to operate wells with insignificant pump working submergence without risk of failure of fluid feed due to pump blocking by gas.

• pumps with non-removable single (THM-C) or doubled (THM-CC) standing valve and built-in drain beating device. Diameter of standing valve (seat and ball) in pumps of diameters 32, 44, 57 mm is oversized. Fishing tool is not available. Fluid is drained from tubing through a hole in beating screw which is broken with beating tool thrown into well.

PRESSURE VALVE КО-73

Pressure valve KO-73 is intended for interval pressure testing of tubing string when run-ning down centrifugal pump, as well as for shutting off fluid flow when pump stops.

It is used during well operation without sucker rods and is installed in tubing string above a pump.

DRAIN VALVE SKOK

Detachable drain valve is intended for fluid drain out of tubing string. When used in combination with tubing pump and non-removable standing valve (THM-T), drain valve is installed on upper coupling of a pump or in tubing string above a pump.

In order to reuse a valve, it is necessary to install a new tear-off shank. Shanks are included in a spare parts delivery set.

To drain fluid out of tubing string when running a pump, pressure required for valve operation is produced in the string. At the same time, neck of tear-off shank breaks. After that, valve piston comes out of a barrel and lets drain fluid pass through holes of valve cage into annulus. When ordering, specify valve designation and operating pressure (if not specified, valves are delivered with operating pressure of 20 MPa).

SHUTDOWN VALVE KON

Shutdown valve is intended for well overhaul without their killing if pumps are changed without tubing pull-out. It is installed under seating nipple of rod pump.

Before first running of a pump, under the action of formation pressure and a spring a valve (seat-ball) is closed, side holes in valve cage are opened, through which fluid flows in tubing.

When setting a pump in seating nipple, it pushes a shaft spindle. A spindle moves piston and a ball, a piston closes side holes, valve is opened, providing suction of fluid during pump operation.

When pulling a pump, a piston stays in the same position (side holes are closed), ball affected by formation pressure and spring, closes valve, preventing fluid flow into tubing, at the same time shaft easily moves upwards. At the next running of a pump, the valve is opened again with the help of the shaft.

68 69



SEALING INSERT

The sealing insert has the central channel for the cable of the geophysical instrument. The cable is sealed with rubber rings.

BLIND INSERT

The blind insert overlaps the central channel of the pump and lets the fluid flow from the tubing to the injectors through the side channels. When the working fluid comes out of the nozzle, the underpressure zone is formed in the mixing tank, where the bed fluid enters and comes off in the hole clearance through the diffuser. The reduction of the bottomhole pressure is checked by the gage, installed on the insert.

ACID PREVENTION INSERT

The central channel of the insert is closed by the valve with the spring-loaded ball. Under the impact of the fluid pressure in the tubing the valve opens and allows the acid solution to penetrate into the bot-tomhole formation zone with shutting off the fluid flow in the side channels.
