Research on status and key technologies of high-temperatureseawater drilling fluids

Abstract:

This paper focuses on the research and application of anti-high temperature seawater drilling fluids additives and systems at home and abroad,some suggestions for the research directions of key technologies of high temperature seawater drilling fluids are put forward. The future direction researches of ultra-high temperature seawater drilling fluids technology is high temperature and salt resistant drilling fluids additives(such as：salt - resistant filtration reduction agent、tackifier、Anti - collapse inhibitor、lubricant), systems, testing instruments, environmental protection, etc.
