摘要：Nowadays, the oil-based drilling fluid has become more and more popular because of the limitation of the type of the exploited oil and gas wells. In this paper, a new type of oil-based drilling fluid formulation is developed through the study of organic clay, emulsifier, wetting agent and so on. It is proved by the experiment that the recovery rate of drilling fluid slurry reaches more than 80%, the demulsification voltage is more than or equal to 2000V, the ability of anti high temperature is very strong, and the pollution to the oil layer is very small.
