【Abstract】 This paper summarizes the progresses made by Sinopec in drilling fluid technology, and introduces the performance and application of positively charged drilling fluids. Analyses are done as to the study and application of solids-free low density drilling fluids, the application of ultra-low filtration drilling fluid technology in the Xingzhuang Project in Jiangsu Oilfield, the application of high salinity micro-foam drilling fluid technology in Jiangsu and Jianghan oilfields, as well as the application of filming water based drilling fluids in Jianghan Oilfield. Protection of fractured gas reservoirs, and mud loss control in northeast Sichuan are also analyzed in this paper. Key points of drilling fluid technology development in the coming several years are presented.更多还原
