Drilling Fluid and Completion Fluid | Year: 2014

Vegetable oil as the base oil of oil base drilling fluid has the advantages of low drilling cost, non-toxicity, no aromatic hydrocarbon, environmental friendliness, bio-degradability, low waste disposal cost, and high comprehensive benefit. The main component of vegetable oils, fatty glyceride, has high chemical activity. Other additives can be optimized for best performance of oil base drilling fluid through laboratory experiments. An all-vegetable-oil (biodiesel) base drilling fluid formulation, which can be used at 150℃ is composed of base fluid (vegetable oil:20%CaCl2=95:5), 3% emulsifier, 2% organophilic clay, 4% filter loss reducer, 1% CaO and required amount of barite. This formulation has very good resistance to water, clays and gypsum contamination, satisfying the needs for field engineering operation. ©, 2014, North China Petroleum Administration Drilling Technology Research Institute.
