As an important part of drill string, drill collar can supply the drill bit and increase the rigidity of drill string. Drill
collars are manufactured strictly according to API Spec7-1 standard with material of AISI 4145 Mod. We supply slick drill collars, spiral drill collars, etc. The size of drill collar we can provide is from 3.1/8 to 11 inches. We can also provide other drill collars at customers’ specific request.
The Spiral Drill Collar is an essential oilfield tool designed to enhance drilling efficiency and safety. Its key feature is a spiraled, grooved exterior that reduces the surface contact area with the wellbore. This design minimizes the risk of differential sticking, a common cause of stuck pipe. Furthermore, the grooves provide improved annular flow paths for drilling fluids, resulting in better hole cleaning and cuttings removal. The tool also increases torsional stability and standoff within the borehole. It is a robust, heavyweight component that provides the necessary weight on bit for effective drilling, especially in demanding directional applications.
