| Abstract: | As a volumetric power drill, the screw PDM has good output hard characteristic and is one of the most widely used downhole power tools. The heat resistance of the screw drill is the research hot spot, improvement of which can expand its application scope and extend its working life. It has a good development prospect in the field of deep high temperature drilling. This paper introduces the basic principle and characteristics of screw drilling tools, and investigates the current development of conventional screw drill tools with the focus on the development status quo of all metal screw drilling tools and the development of domestic metal screw drilling tools. The development trend and key technology of the all metal screw drilling tool are put forward to provide reference for domestic research and development of the leading edge tool. |
