摘　　要：针对临兴区块甲基聚合物钻井液,开展了放置不同时间后再重复利用可行性的室内实验研究。结果表明,钻井液放置5天后粘度降低且API滤失量升高,而通过调高pH值,加入0.02%的杀菌剂、加入0.3%的降滤失剂等手段,可维持钻井液性能指标在初始水平,现场重复利用钻井液具有可行性。The feasibility of recycling K+-base polymer drilling fluid from Lin-Xing gas area after laying up some days were investigated by means of lab experiments.The results shows that the viscosity decreasing and the API filtration increasing since the fifth day,but using some kinds of methods such as enhancing the pH value,adding 0.02% bactericide,adding 0.3%fluid loss additives,the properties can be maintained to the initial level so recycling drilling fluid is possible.
