ZJ30 Skid-Mounted Drilling Rigs
ZJ30 skid-mounted drilling rig is suitable for drilling wells in the depth lower than 3000m. It can work in different sort of environments like shallow sea areas, beaches, desert and cold areas.
Features
- The key components of this machine are driven by mechanical transmission. The whole machine is a highly cost effective product which is easy to operate and maintain.
- The drawworks is mainly driven by sealed chain transmission system supplemented with an auxiliary driving device used to hoist the derrick in emergency situations. Designed with an integrated compound chain transmission case, the drawworks features low failure rate, easy operation and maintenance.
- This skid-mounted rig is equipped with an integrated control cabin for the driller to take charge of most of the operations. Since the control cabinet is assembled on the drawworks-fixed water tank, negative influence on the instrument and control components in the control cabin caused by drill floor vibration will be reduced.
- With proper overall structure, our skid-mounted drilling rig can meet the need of integral hoisting as well as removal in block by train or automobile.
