Valve Cover

Valve cover, bonnet, valve part with stem seal for connecting or supporting actuators.

Use oil drilling equipment to drill through multiple sets of formations from the ground along the designed track to reach the predetermined target layer (oil and gas layer or possibly oil and gas layer), and form a stable channel (i.e. oil and gas) for oil and gas production or injection of required fluids (water, gas, steam). wells), and during drilling and after drilling, complete coring, logging, logging and testing work, and obtain systematic engineering of various information required for exploration, development and drilling.

Drilling equipment mainly includes oil drilling rigs, drilling tools, drilling instruments and auxiliary equipment. The drilling rig used in the rotary drilling method is mainly composed of derrick and lifting device, power machine and transmission device, drilling pump and drilling fluid circulation system, etc., which are used to realize the lifting and rotation of drill string (string) and the circulation of drilling fluid. Drilling tools and drilling instruments are used to control formation pressure during drilling and monitor and control drilling process parameters.
