- Model ZJ40/2250L and Model ZJ40/2250LB, 1000HP, mechanical land drilling rigs are designed to drill and complete oil and gas wells with a depth of 2500m-4000m by using 4-1/2″ API drill pipe. The drilling rigs are mainly equipped with 43m high open-front type mast, module mounted substructure with 6m drill floor height and 800mm rear drill floor height, chain-drive transmission system.
- Two each 1300HP, 5000psi working pressure, mud pump equipped with the rig, used for the high pressure drilling fluid circulation, complete with mud discharge manifold, standpipe manifold and standpipe.
- Three each model PZ12V190B-3 diesel engines or equivalent, compete with YB900 torque converter are used to be the main rig power that is transmitted into a chain drive compound box. The compound boxes with three input shafts are designed to drive two 1300HP mud pumps, drawworks, and rotary table.
- The hoist and traveling system has a nominal load capacity of 2250kN that is 250 short tons. The key rig components, such as drawworks, crown block, traveling block, swivel, rotary table, hook, mud pump, high pressure valves, mast, and substructure, conforms to API Specifications.
- A two air compressor source system is available on the rigs, used to power all the air users, such as air hoists, air pumps on BOP pressure control system, air winch on stabbing board.
- Mud pump driven by universal shaft through chain compound
- Rotary table driven by an independent system consisting of chain box and universal shaft, powered by a frequency variable AC motor, or by gearbox and shaft powered by chain compound
- Drawworks driven through chain compound transmission
- The electrical applicants and equipment such as AC motors, lights, and switch boards, are explosion-proof and well protected.
- Drilling instrument system monitor and record drilling operation data, including weight on bit, rotary table speed and torque, well depth, mud pump stroke and pressure, standpipe pressure, mud return volume, liquid level and volume of mud tanks, etc.
