ZJ20DBX Slant Well Drilling Rig

The rig has skid-mounted modular structure, VFD drive, and driller's cabin integrated by electric, liquid, pneumatic controls, display, monitoring, and communication, which can monitor the complete rig. The domestic-made wellhead automatic tools are firstly used in the rig which is highly mechanized and automatic. It can drill slantingly from the ground after the mast is slanted for a certain degree and it is used for 2000m slant well or 3000m vertical well. Compared with conventional rig, it can reduce the covering area of the rig yard and moving time of the rig, and can be widely used in offshore, foreshore and land slant well, vertical well, slant directional well, cluster well, as well as geothermal well.
