How to More Effectively Extend The Service Life of Oil Drill Pipes

Oil drill pipes are key drilling accessories that connect drilling tools and drilling rigs. They play a key role in transmitting the drilling force and mud fluid of the drill bit. Now they have gradually been widely used. For the majority of users, how to effectively extend the service life of oil drill pipes is explained in detail below:Drill Pipe

1. Improve the comprehensive mechanical performance of geological drill pipe materials and the production process level of hollow steel, and reduce various internal and external defects of geological drill pipes as much as possible to ensure that geological drill pipes have high quality and service life. Of course, precise operation and management during rock drilling, as well as their respective processing accuracy, are also the basic conditions for ensuring the life of geological drill pipes.

2. Continuously improve the structure of rock drilling machines. For example, the piston of a pneumatic rock drill with a large end and a small end has grown to an equal-diameter cylindrical piston of a hydraulic rock drill. While ensuring that the rock drilling speed continues to increase, the waveform of the rock drilling stress wave has been changed and the crushing stress on the drill pipe has been reduced.

Drill pipe is a seamless steel pipe with a corrugated tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to be pressed, twisted, bent and vibrated. In the process of oil and gas extraction and refining, the drill pipe can be used many times.

The drill pipe joint is the weakest link of the drill pipe. According to statistics, more than 80% of drill pipe fracture accidents occur at the drill pipe joint. In order to solve the wear problem of the drill pipe joint and the casing, the most common method is to weld a wear-resistant alloy layer on the drill pipe joint to form a wear-resistant belt with a certain thickness. The drill pipe wear-resistant belt protects the drill pipe and casing from strong wear with its certain wear resistance and wear reduction.
