| Abstract: | High-density saturated brine drilling fluid is contaminated by formation materials during drilling into salt-gypsum layer, resulting in an increase of viscous shear thickening. In this study, the maintenance technology of viscosity shear suppression is adopted to solve this problem. A brine drilling fluid with density of more than 2.0g/cm3 is weighted with ordinary barite powder, and is applied to drilling high-pressure gas-bearing salt-gypsum layer in South Yoloten gasfield, Turkmenistan, which obtains goo... |
