摘　　要：深部油气藏逐步开发,钻井过程中,要求钻井液具有优异的抗高温性能,使钻井液在井壁内具有良好的携岩、护壁能力。油基钻井液抗高温性能受乳化剂、有机土、降滤失剂的影响甚大,本文综述了高温对油基钻井液性能的影响,并介绍了油基钻井液重要的抗高温处理剂(乳化剂,有机土,降滤失剂)以及抗高温油基钻井液的应用。With the gradual development of deep oil and gas reservoirs,the drilling fluid was required to have excellent high temperature resistance in the process of drilling,so that the drilling fluid had a good ability of carrying rock and protecting the wall in the well wall.The high temperature resistance performance of oil base drilling fluid was greatly affected by emulsifier,organic soil and fluid loss reducer.This paper summarized the influence of high temperature on the performance of oil base drilling fluid,and introduced the important high temperature resistance treatment agents(emulsifier,organic soil and fluid loss reducer)of oil base drilling fluid and the application of high temperature resistance oil base drilling fluid.
