摘要
Abstract
In the process of drilling brine wells,the technical casing cementing operation faces challenges such as large wellbore diameter,low displacement efficiency,long open hole section in the second opening,complex geological conditions,long cementing operation time,and affecting cementing quality.By strengthening wellbore preparation,strengthening casing measures,optimizing cement slurry system and cementing technol-ogy,the quality of cementing construction is ensured,and the problem of large opening diameter is effectively solved There are many difficulties such as excessively long open hole sections and uneven formation pressure,which ensure the safety of subsequent construction and mining,and are of great significance for drilling and mining deep mineral resources.关键词
