鄂尔多斯盆地深部复杂地层钻井液技术
摘要
Abstract
In this paper, the difficulties encountered in deep troublesome formations of Ordos basin are summarized and a high inhibitive performance sealing anti-caving drilling fluid system is developed, that is stable at as high as 180 ℃. The application in the exploration well DB8 shows that it can inhibit soft mud stone hydrating and drill through out 300 m of cement plug safely. Furthermore, it decreases the mud losses at least by 50%, and the borehole enlargement rate of coal formation is only 7.33%.关键词
