Description

Technical Field

[0001] The utility model relates to the technical field of a non-magnetic drill collar body, in particular to a non-magnetic drill collar body provided with anti-sand protection. Background Art

[0002] The non-magnetic drill collar body is made of a low-carbon, high-chromium-manganese alloy steel. It is refined after strict chemical composition ratio and achieved its mechanical properties through forging. It has good low magnetic permeability and high strength mechanical properties. The non-magnetic drill collar body is mainly used to determine the direction of the wellbore during directional well drilling. At the same time, it creates a non-magnetic environment for magnetic measuring instruments during the directional process to ensure that the data measured by the magnetic measuring instruments are real geomagnetic field information.

[0003] In the prior art, a wear-resistant non-magnetic drill collar body with publication number CN218816270U comprises a non-magnetic drill collar body, a plurality of annular grooves are provided on the side wall of the non-magnetic drill collar body, and anti-wear mechanisms are installed in the plurality of annular grooves; the anti-wear mechanism comprises a first mounting member and a second mounting member, the first mounting member and the second mounting member are both semi-circular ring structures, and anti-wear layers are fixedly installed on the outer ring side walls of the first mounting member and the second mounting member, respectively. When the utility model is used, the first mounting member and the second mounting member are wrapped in the annular grooves on the non-magnetic drill collar body, and the first mounting member and the second mounting member are fixedly connected together through a connecting mechanism. The anti-wear layers arranged on the outer ring side walls of the first mounting member and the second mounting member will be higher than the outer wall of the non-magnetic drill collar body, thereby realizing protection of the non-magnetic drill collar body. At the same time, the connecting mechanism is very convenient to install and disassemble, and the anti-wear mechanism can be replaced at any time after the anti-wear layer is worn and consumed.

[0004] The above patent proposes that the existing non-magnetic drill shank body usually has an anti-wear mechanism that can be replaced at any time after the anti-wear layer is worn and consumed. However, it is inconvenient to disassemble and replace the surface protection structure of the non-magnetic drill shank body during use, so that one damage causes the entire body to need to be discarded, wasting resources and reducing the practicality of the device. During use, due to different usage scenarios, mud and sand are easily entered into the inside of the non-magnetic drill shank body, resulting in excessive accumulation of mud and sand inside for a long time, reducing the working efficiency of the device. Therefore, the utility model provides a non-magnetic drill shank body with anti-mud and sand protection. Summary of the invention
