This 750 HP Heli Portable Drilling Rig is no longer needed for company's own operation and is being sold as an asset liquidation for its owner.
"LEWEK EXPLORER 750" is a Heli Portable drilling rig designed with layout meeting requirements for helicopter hoisting, with assembly by an on-site crane. The drilling rig mainly comprises of a draw-works support chassis, mast, drill floor sub-structure and specialised drilling equipment. The rig had also completed her winterization works in Houston, USA.
The rig consists of the main draw-work 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 VFD, hydraulic air and electric system). The operation is centralised 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 and telescoping mast is made of rectangular tubes. Its clear height is 38 M (vertical distance from crown block beam to ground) and 32 M 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 29 MM 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 dismantle.
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 & 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 controls are installed in the driller cabin. Cathead is remote controlled. Key components are imported.
Rig is complete with AC460V, 60 Hz 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 circulation system
Scoping type substructure completes with walkway, ladder, "V" door ramp. The substructure is designed with reinforced mouse and rate 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.
