液力衡扭旋冲提速工具及其在达深16井的应用
Application of Hydraulic Constant Torque Rotary Percussion Tool in Dashen16 Well of Daqing Oilfield
摘要
Abstract
Due to the hard and strong abrasive rocks in deep formation of Daqing oil field, the use of conventional drilling method with single bit means low run footage, short bit life and low ROP;these are effectively improved by the application of hydraulic constant torque rotary percussion tool.The field tests in Dashen 16 well prove that by the use of hydraulic con-stant torque rotary percussion tool, the rock breaking mode of bit can be attached with mechanical impact and high pressure hydraulic pulse on the basis of shearing, and the shearing efficiency of PDC bit can be greatly improved, which is an effec-tive means to improve ROP of deep well drilling.关键词
