Non magnetic drill collar is one of the important components of drill string, which provides drilling pressure to the drill bit and improves the rigidity of the drill string.
The non-magnetic drill collar is mainly used as a device to monitor whether the borehole is drilled according to the designed trajectory. It is a drilling tool that detects the azimuth angle of the borehole and accurately measures it.
Non magnetic drill collars are used to increase the weight of the drill string, providing a large drilling pressure for the drill bit and accelerating the drilling speed. Due to the strong rigidity and good stability of non-magnetic drill collars, they also play a role in stabilizing the drill bit and maintaining the wellbore trajectory. Spiral drill collars and non-magnetic drill collars belong to the category of drill collars. Spiral drill collars are machined with three spiral grooves on the cylindrical surface of the entire drill collar to reduce the contact area of the wellbore. Spiral drill collars can prevent pressure drop and drill jamming. And non-magnetic drill collars are mainly used for monitoring during oil drilling processes.
