  • An ultra-high temperature water base drilling fluid was prepared with high temperature filter loss reducer MP488, high temperature rheology stabilizer CGW-6 and high temperature filter loss reducer HTASP-C with good salt tolerance. The drilling fluid, having density of 2.3 g/cm3, was able to tolerate salt (NaCl) contamination to saturation, and percent recovery of shale sample in hotrolling test of was 94.1%. It also had good suspension capacity and tolerance to clay contamination. This drilling fluid was suitable for use in high temperature (260 ℃) well drilling, with its density being adjusted between 2.0 g/cm3 and 2.5 g/cm3.
