摘　　要：随着当今社会对于石油的需求的持续增加,易开采的石油资源越来越少,油气勘探已向深井、超深井等复杂地层方向发展,钻井液作为钻井系统工程中的重要组成部分,在深井中面对复杂地层时,提高钻井液的性能尤为重要。以塔里木盆地库车坳陷选用的油基钻井液为研究对象,研讨了不同油基处理剂对油基钻井液抗盐水污染的影响,从而为解决钻探过程中高密度油基钻井液抗盐水侵污染问题提供现实指导意义。With the increasing demand for oil in today’s society, there are fewer and fewer easy-to-exploit oil resources, and oil and gas exploration has developed to deep wells, ultra-deep wells and other complex formations. As an important part of drilling system engineering, it is particularly important to improve the performance of drilling fluid when facing complex formations in deep wells. In this paper, taking the oil-based drilling fluid selected in Kuqa Depression of Tarim Basin as the research object, the influence of different oil-based additives on the salt water pollution resistance of oil-based drilling fluid was discussed, so as to provide practical guiding significance for solving the problem of salt water pollution resistance of high-density oil-based drilling fluid during drilling.
