摘　　要：某井是四川地区的岩气能源勘探井,由于该井口施工地区气层十分活跃,所以井口控制风险性较大,必须始终维持钻井液质量和使用性能,但是由于超高密度复合盐水钻井液固相控制难度参数高,造成钻井液流变性十分困难。根据某井实际案例作为研究出发点,并且结合超高密度复合盐水钻井液影响因素以及超高密度复合盐水钻井液流变性调控,总结出应用策略。A well is the rock gas energy exploration well in Sichuan region, due to the wellhead gas construction area is very active, so the wellhead control risk is bigger, the quality and service performance of drilling fluid must always be maintained, but the rheological control of drilling fluid is very difficult because of the high difficulty parameters of solid phase control of ultra-high density compound brine drilling fluid. In this paper, based on the actual case of a well as the starting point of the study, combined with the influence factors of ultra-high density compound saline drilling fluid and the rheological control of ultra-high density compound saline drilling fluid, the application strategies were summed up.
