| Abstract: | A series of high density drilling fluids, with the highest density being 2.9 g/cm3 are formulated based on studies conducted on some critical parameters of high density drilling fluids, such as the content of bentonite in drilling fluids, the optimization of weighting agents and surfactants. These fluids are stable at temperature as high as 150 ℃, and salinity up to saturation. Laboratory experiments showed that these fluids have good rheology. Field application in several wells, such as Yangtake-101, Dina-22, Dabei-1,Hetian-1, Zhuang-2, Gu-1, Heba-1 and Heba-2 gives satisfactory results. |
