固井水泥车车载密度计清洗装置
本技术涉及油田开发钻井工程
,特别涉及一种固井水泥车车载密度计清洗装置。
技术介绍
车载密度计是固井水泥车重要组成部件之一,其作用是在日常固井施工时实时监测水泥浆密度,保证油井固井施工质量,为油田后续开采提供可靠保障。随着固井技术的不断发展,固井工艺也发生改变,根据不同区块油井设计,固井施工混配水泥浆时需加入外加剂以保证水泥石强度。在日常施工时,受水泥浆外加剂及人为操作失误等原因影响,密度计内部震荡管经常发生水泥石挂壁现象,导致密度计对水泥浆密度检测失准。所以,为保证监测的准确性,密度计需在连续施工20口井或半个月进行一次常规清洗。密度计由箱体、双U型震荡管、三个电子传感器以及一个信号发射器组成,清洗时主要清洗其内部双U型震荡管,保证震荡管内壁清洁,准确监测水泥浆密度。受固井水泥车构造影响,常规清洗时为满足水泥车内部循环要求,需先在水泥车混浆池内混配好1m³药液,通过二次循环将药液泵送至密度计内反复循环冲洗完成清洗。常规清洗方式主要存在以下几点不足:(1)药液量大,虽然密度 ...
