一种完全不含商业黏土或褐煤的合成基钻井液, 在目前已钻的80余口井中成功阻止了重晶石的沉降, 避免了常规含黏土合成基钻井液为控制重晶石沉降所产生的复杂结果。在钻井、下套管和固井中钻井液漏失总量平均降低60%; 通过随钻压力测试数据证实可明显降低当量循环密度; 用最小的初始压力就可破坏高平缓的静切力; 达到墨西哥海湾作业环保法规最高标准。 A synthetic drilling fluid that is completely free of commercial clay or lignite successfully blocks barite settling in more than 80 wells drilled so far and avoids the need for conventional clay-based drilling fluids to control barite settling The complex result. Drilling down casing and cementing drilling fluid lost an average of 60% of the total loss; by the while drilling pressure test data confirmed that can significantly reduce the equivalent circulation density; with the smallest initial pressure can destroy high gentle resting force; to Mexico Gulf operations environmental regulations the highest standards.
