What are the characteristics of oil for rod thread
2024-12-051. Good lubricity One of the characteristics of drill pipe thread oil is its excellent lubrication performance. During the drilling process, the drill pipe needs to be frequently connected and disassembled, and the friction between the threads will generate a large amount of heat. Drill pipe thread oil can effectively reduce the friction coefficient between threads, making the connection and

What is the function of a mud pump
2024-11-02Mud pump is a device used to transport liquids containing solid particles such as mud. Its main functions are as follows: 1、 In the field of drilling Transporting Mud: During geological drilling, the prepared mud is transported into the borehole to cool the drill bit, carry rock debris, and balance formation pressure. The mud pump generates a certain pressure to circulate the mud in the bo
