The latest research progress of the technology of JZZY-1 downhole drill string absorption hydraulic supercharging device to improve the drilling speed

The field test results show that the downhole drill string absorption hydraulic supercharging device based on the research on the drill string vibration can assist breaking downhole rocks and increase rate of penetration by ultra-high pressure water jet. In order to improve its working performance, the structure was optimized and the Ultrahigh pressure bit runner system was invented. After optimization, Processing, installation, disassembly and maintenance of this device are more convenient. And the Ultrahigh pressure bit runner system assembly with common bit could work with the downhole drill string absorption hydraulic supercharging device, which was proved significantly increasing drilling speed by the test evaluation of 2 wells in Shengli oilfield.
