This rig123.net' target='_blank'>drilling rig can be used to drill water wells with a depth of 985ft and wellhead diameter of 1.6 ft. It can also be used to drill the gas wells of the same specification and also can engage in workover operations.
The water-well drilling rig is a kind of mobile rig. The heavy-duty and cruise chassis is chosen for loading the hoisting/spinning and circulation system integrally, which has a perfect movement.
With a full hydraulic drive, the operations of this kind of drilling rig, such as hoisting operations, spinning operations, mud circulation and power drive, use a hydraulic loop system. The drilling parameters can realize stepless regulation.
The water-well drilling rig also has an auto driller system and high working efficiency, by equipped with a pressure device for pressurization and depressurization to DP.
A hydraulic brake and a Crown-O-Matic are adopted to meet drilling-process requirements, and an emergency hydraulic source is installed on the chassis to ensure the safety and reliability of the rig.
