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 API 7-1 Spiral Drill Collar is a specialized heavyweight component within the bottom hole assembly. Its primary function is to provide substantial weight on bit for efficient drilling while minimizing the risk of differential wall sticking. The key feature is its spiraled, grooved outer surface. This unique design significantly reduces the contact area between the collar and the wellbore wall. Consequently, it enhances fluid flow for better hole cleaning and improves the overall stability of the drill string. This robust tool is essential for maintaining wellbore trajectory and optimizing performance in demanding directional drilling applications, helping to prevent costly stuck pipe incidents.
