Oil Drilling Rig for Drilling Machinery 2000HP CD-AC

Model NO.: CD-AC Power Type: Diesel Rig Type: AC Electric Trailer Rig Tractor Hoist Type: Wheeled Tractor Hoist Drill Bit Size: 9 1/2 inch Transmission System: Hydraulic Trademark: CHANCE DOOR Origin: Chance Usage: Well Drilling Machinery Type: Petroleum Drilling Machine Drilling Depth: 7000m Offshore Unit Type: Jack-up Drilling Rig Drill Bit Blade: 5 Certification: API Specification: API HS Code: 84314310 The main power of the drilling rig is from 3 sets of CAT3516B 1850KW or 4 sets of CAT3512B 1100KW diesel generator sets. It adopts the advanced digital AC variable frequency technology. By means of the integrated design of electric transmission system PLC, touch screen and drilling instrument parameters of gas, electricity and fluids, the operation of intelligent control by driller is fully realized.
It has front-open mast and double-hoisting substructure. The mast and all devices on the floor can be installed at a lower position. Drawworks is driven by shingle-shaft gear with one-shift stepless speed governor, which makes the mechanical transmission easy and reliable. The main brake is hydraulic disc brake and the auxiliary brake relies on energy consumption of motor. It is equipped with an automatic driller, which makes the operating control system simpler, easier and more convenient and the drilling operation safer and more reliable.
The configuration of drilling rig meets the requirement of explosion-proof, safe drilling operation, convenient installing, disassembling and maintaining of equipment as well as the requirement for installation of top drive. In addition, it can be raised by the power of drawworks.
The drilling rig can be divided into five areas, drilling floor area, pump house area, power/electric control area, mud circulation area, and water tank & fuel tank area.
