    Abstract
  • Invasion of low quality solids, especially the low density solids is one of the major factors causing the thickening of high density oil based drilling fluids. The low quality solids in an oil based drilling fluid, when in contact with the wetting agents and emulsifiers therein, attain a certain degree of activity, thereby strengthening the networking structure and increasing the viscosity and gel strengths of the drilling fluid. A viscosity reducer CQ-OTA with amino groups and amido groups in its molecules was developed with lauramide, octadecanamide and erucamide in a mass ratio of 1∶2∶1. Evaluation on the viscosity reduction capacity of CQ-OTA showed that it can reduce the plastic viscosity and gel strength by 25.0% and 60.0% respectively of a high density thickened oil based drilling fluid containing 48.5% solids. The recommended treatment of CQ-OTA in oil based drilling fluids is 0.5%-1.5%. CQ-OTA was used on the Wei-202HX platform and it effectively improved the rheology of the oil based drilling fluid. The threshold of the low quality solids in the drilling fluid was increased. The plastic viscosity of the oil based drilling fluid was reduced from 53.0 mPa·s to 40.0 mPa·s, the final (10 min) gel strength reduced from 23 Pa to 14.5 Pa, ensuring the successful drilling of the well with the oil based drilling fluid, and enhancing the efficiency of reusing the high density oil based drilling fluid. The drilling cost was thus greatly reduced.
