Application Research on Low-Pressure Pulse and Cavitation Jet Compound Drilling Technology

Abstract:

Article Preview

In the low-pressure pulse and cavitation jet compound drilling technology, pulse low-pressure and cavitation jet generator is installed on bit, water jet modulated by generator can generate pulse low-pressure, which will alternate rock mechanics, decrease rock breaking strength, increase rock-breaking efficiency. And cavitation jet generated can increase hydraulic power downhole. The results show that low-pressure pulse and cavitation jet generator has been run well from 5349m to 6162m for 129.36h-136.63h in TK1090 well, increasing drilling speed 40.6%~85.1%. The low-pressure pulse and cavitation jet compound drilling technology can increase drill speed and be deployment in deep well drilling.
