Why Non-magnetic Drill Collar Is Essential Equipment?

With the continuous advancement of technology, various types of processing tools have been developed well, for the non-magnetic drill collars, it has become one of the necessary drilling equipment in the drilling industry. Today, as the device manufacturers, we summarize the relevant non-magnetic drill collars content related effects, we should you not miss.

In fact, non-magnetic drill collars is made of low-carbon high-chromium-manganese alloy steel, it is the result of stringent chemical composition ratio by forging and refining to achieve its mechanical properties. The device can be prevented drill string differential block during drilling pressure, spiral groove allows the mud flow freely around the drill collar to prevent the formation of pressure balance block, thereby effectively preventing differential sticking phenomenon. Of course, also possible to reduce the area of contact with the borehole wall, it can effectively reduce the possibility of generating a differential pressure block.erating a differential pressure block.
