LS30H-AC drilling rig mainly comprises of a draw-works support chassis, mast, drill floor sub

structure and specialized drilling equipment. The rig is designed with advanced technology,

improving the reliability as a whole. The operation and maintenance are ergonomic. Critical

components are imported. The rig is equipped with interface with relative equipment. The rig

meets the drilling requirements.

Power system: C-18 Generator Sets, three (3) New Caterpillar C-18570KW 460 V 60 hz

The rig dedicated devices consists of the main draw-works frame, raising system (including

draw-works and brake system, auxiliary brake), traveling system (including crown, wire line),

mast, rotating system (including hydraulic powered rotary table), control system (including

VFD, hydraulic, air and electric system). The operation is centralized on the hydraulic control

console and drillers control cabin.

Four hydraulic jacks are attached to the main draw-works frame and are used to level the rig

and bear the rig weight when the rig is working. A mechanical jack is set at the front of main

beam and two mechanical jacks are set at the middle of main beam.

The double section and telescoping mast is made of rectangular tubes. Its clear height is

38m (vertical distance from crown block beam to ground) and 32m from crown to floor.


It includes upper mast section, lower mast section, base, braces, crown block and monkey

board. The raising, lowering of mast and telescoping of upper mast section is accomplished

by wire line scoping.

Drawworks mainly consists of frame and guard, main drum and braking system, air- cooling

disc type parking and emergency brake. Drum shaft is made of premium alloy steel. Brake

discs are alloy steel. The main drum is Lebus grooved, which ensures orderly arrangement

and long service life of 29mm wire line. Main brake is regenerative AC type. Newly designed

high strength structure is adapted to the fabrication of frame and guard for easy installation

and dismantlement.

Rotary table driving device includes rotary table hydraulic driving unit.

Main hydraulic system is equipped with oil tanks, filters, gear oil pumps, overflow valves and

supplies clean and high-pressure hydraulic power. The rig hydraulic system controls rig

adjustment and hydraulic floor tools. Rig adjustment includes leveling of frame, raising,

lowering of mast, and its manual sextuplet valve is installed at the back of carrier. Hydraulic

floor tools include hydraulic winch, two cathead cylinders, and spare oil ports. The hydraulic

winch is electric remote-controlled and hydraulic-powered the controls are installed in the

driller cabin. Cathead cylinder is remote controlled. Key hydraulic components are imported.

Rig is complete with AC460V, 60HZ lighting and power distribution cabinet. Three branch

lines supply power for the lighting of mast, substructure, and carrier. Two branch lines 460V

supply power for circulating system.

Scoping type substructure completes with walkway, ladder, "V" door ramp. The substructure

is designed with reinforced mouse and rat holes. BOP Trolley beams are supplied for

mounting, Ingersoll Rand, BOP hoist. The setback area is using anti-corrosion wood. Groove

is designed under the setback for mud down flow. There is drip pan between wellhead and

substructure for collecting the mud.

8 Rig Hydraulic System

The Hydraulic Power system is dual power, first system is Diesel driven to allow the mast to

be erected before the electrical system is completely installed. The AC powered HPU uses

the same tank for hydraulic oil as the diesel unit. The HPU also has an isolated small AC

Driven HPU to power the disc brakes for the Drawworks, all modularized to be a single lift.

The unit is fully capable of powering all of the hydraulic equipment on the floor except the top

drive which has a stand alone system. The HPU is mounted under the substructure and

plumbed to quick connections as required for leak- free disassembly.
