Description

Technical Field

[0001] The utility model belongs to the field of drill rods, and in particular relates to a drill rod with a super wear-resistant coating. Background Art

[0002] During the drilling process, grouting is generally required when pulling out the drill bit. Due to the volume of the drill bit itself and the spraying of some mud when pulling out the drill bit, the mud level in the wellbore will drop. If the grouting is not done for a long time to maintain the liquid level, the liquid column in the well will become shorter and the bottomhole pressure of the liquid column will become lower. At the same time, a negative pressure will be formed due to the suction effect during the drilling process. The superposition of the two will greatly destroy the underground pressure balance (the balance between the formation pressure and the mud column pressure). When the formation pressure is greater than the liquid column pressure, it is very likely to cause a kick or even a blowout. In order to balance the formation pressure and ensure underground safety, especially in wells with high-pressure oil, gas, and water layers and wells without surface casing, mud must be injected in a timely manner.

[0003] Since the drill pipe often comes into contact with the gravel in the wellbore during rotation, the connection between the two drill pipes will often be ground by the gravel, causing damage to the connection of the drill pipe, thereby affecting the service life of the drill pipe.
