Research on Structural Optimization of Oil Bit Screw Thread

Abstract:

Abstract: With the development of drilling technology and demand, the working environment of oil bit with bearing a greater load has become increasingly harsh, which lead to occur frequently fracture on oil bit screw thread. In this paper，optimization research on oil bit screw thread is mainly presented, along with improvement scheme of structure from five aspects, and taking API 7 5 / 8 "REG (V-050) as an example, design on structure optimization of oil bit screw thread is completed so as to enhance structural strength of oil bit screw thread, thus reducing or even avoiding the occurrence of screw thread fracture of oil bit and meeting the demand for field use.
