Drilling Fluid and Completion Fluid | Year: 2015

A new emulsifier was developed to mitigate the problems of oil base drilling fluid such as high viscosity and low gel strength which are negative to the suspension and carrying of drilled cuttings. An oil base drilling fluid was formulated with this new emulsifier. The properties of this mud were as follows: density 1.0-1.7 g/cm3, plastic viscosity ≤540 mPa·s, ratio of yield point to plastic viscosity 0.35-0.50 Pa/mPa·s, and electric stability ≥800 V. This mud had good rheology and was tolerant to contamination by water to 15%, and drilled cuttings to 10%. This mud had been successfully used in Well Jiaoye54-1HF. ©, 2014, North China Petroleum Administration Drilling Technology Research Institute. All right reserved.
