摘要
安徽油田总结１９９４年前水泥净浆固井存在的问题有水泥浆析水量大，驱替钻井液效果不佳，环空水泥浆倒流等。通过两年多来的实践探索，总结出在不具备水泥外加剂干湿混配条件下，井下情况又允许以水泥净浆封固产层套管时的实用固井配套技术。文中分析了净浆固井的必备条件、工艺及成功的实例。
Anhui Oilfield summarized that problems existed in pure slurry cementing before 1994 were too much water filtration,poor displacement capability,counterflow of cement slurry in the annulus,and etc.After two-year study and practice,a new practical matching cementing technology has been developed in sure conditions.The application conditions,process and successful example of pure slurry cementing are analysed.
