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.
LS30H AC rig technical specifications Page 3
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.
