Oil Drill Rigs
Friction Welded Drill Pipe and Adapter
Friction welded drill rods and joints implement API SPEC 5DP and SY/T5561-2008 standards. The drill rods are available in DZ50, R780, G105, and S135 grades, all of which have undergone local or overall heat treatment. The mechanical properties fully meet the standard requirements; the joints are made of high-quality alloys The steel 35CrMo, 4137H and other quenching and tempering...
Drill collar, non-magnetic drill collar
The drill collar is mainly used to provide the weight of the drill bit, so that the drill rod is in a tension state, and the drill bit is used to straighten the drill bit to maintain the borehole trajectory. The drill collar implements the API Spec7-1 specification, the material is 4145H, the overall heat treatment, and the phosphating treatment after the thread is hardened, the anti-sticking...
Square kelly
The kelly rod is located at the uppermost end of the drill string, transmits torque and bears the weight of the drill string, and is the driving part of the entire drill string. The square drill pipe implements the API Spec7-1 specification, the rod body material is 4145H, after the overall heat treatment, the thread is hardened and then phosphated, and the anti-sticking performance...
Heavy weight drill pipe
The structural feature of the weighted drill pipe is medium weight. The drill tool is similar to the drill pipe. Its wall thickness is larger than the drill pipe and smaller than the drill collar. It is generally added between the drill pipe and the drill collar when forming the drill string to prevent the section of the drill string. The sudden change reduces the fatigue of the drill pipe...
Thin Button Drill Pipe and Lock Joints
The thin button drill pipe is made of high-quality seamless steel tube. The end part adopts hydraulic thickening, intermediate frequency heat treatment and threads adopt numerically controlled lathe. The lock joints are processed through special crafts, has excellent performance and credible quality. It can be produced in accordance with standards and customers...
Adapter
The conversion joint plays the role of conversion and connection of drill string components in oil, gas and geological drilling operations, and is one of the main tools for connecting the upper drilling tool and the lower drilling tool. According to customer requirements, various forms of conversion connections can be provided...
Lifting sub
The lifting section is a special tool for lifting drilling tools in non-oil, natural gas and geological exploration drilling projects. It is processed according to SY/T5699-2010 and API Spec 7-1 specifications. The integral structure's lifting subsections are available in 18 degrees and 90 degrees, and can be selected according to the structure of the elevator when used...
Drill stabilizer
Drilling tool stabilizer (also known as centralizer) is an important tool for preventing well deviation in oil, gas and geological exploration drilling engineering.It has a wide range of uses.Whether it is increasing or decreasing slope, it needs to be equipped on the drill string. Install a number of drilling tool stabilizers to improve the wellbore quality and drilling speed and reduce drilling...
