Drilling Rig

We can offer drilling rigs and accessories, depth of which ranges from 1,000 to 7,000 meters, and we can also develop new rig as users’ special request. The drilling rigs are used to explore, develop oil, gas and water well. Its accessories are according to API specifications.

5,000m serial drilling rigs have those types: ZJ50L, ZJ50JD, ZJ50LD, ZJ50JD, ZJ50D and etc. ZJ50L and ZJ50LD drilling rig have exported to oversea, and obtained reputation of high quality.

Main Parameters of 5,000 Meters Serial Rig Description:

Low position Drawworks; Friction clutch shift speed; Main brake is hydraulic disc brake; independent driven rotary table.

Integral chain compound transmission; Drawworks, rotary table and mud pump driven by compound transmission; Friction clutch shift speed; Cardan shaft drive rotary table.

AC-SCR-DC, one to two, digital electric control system; Drawworks, rotary table realize smooth speed change to provide good operation character, start smooth and steady, high efficiency, and distribute load automatically.
