新型油基钻井液体系的研究

Research on A New Type of Oil-based Drilling Fluid

现如今,由于开采油气井类型的限制,油基钻井液越来越受到人们的青睐,本文通过对有机土、乳化剂、润湿剂等的研究,研制了新型油基钻井液配方,通过实验证明,该钻井液井浆回收率达到80%以上,破乳电压均≥2 000 V,抗高温能力强,并且对油层污染很小。

Nowadays, because of the limitation of the type of oil and gas wells, the oil-based drilling fluid has become more and more popular. In this paper, a new type of oil based drilling fluid formulation was developed through study of organic clay, emulsifier, wetting agent and so on. The experiments have proved that recovery rate of drilling fluid slurry can be more than 80%; breaking voltage≥2 000 V; anti high temperature ability and anti drilling cuttings pollution capacity is very strong; and the oil layer pollution is very small..
