Summary:The technical problems of drilling fluid in ultra-deep, unconventional oil/gas, deep water, hot dry rock, polar, natural gas hydrate and other complex formations are systematically sorted out. The key scientific problems and core engineering problems are discussed. Combined with the research progress of drilling fluid technology in recent years, the development of drilling fluid technology for ultra-deep, unconventional oil/gas, deep water, hot dry rock, polar, natural gas hydrate and other complex oil and gas is provided.The problems in the drilling of complex formations, such as hightemperature, high-pressure and high-salinity, serious shale hydration, wellbore instability, large temperature difference, loss circulation, formation damage, and low degree of automation of drilling fluid maintenance, domestic and foreign researchers have developed key material, systems and equipments such as high-temperature and high-salinity water-based/oil-based drilling fluid, constant rheological drilling fluid, antiultra-
