摘要
为提高作业时效,成功研发了一种新型套管丢手内专用冲砂扶正工具,其省略了回接管柱,直接在大套管内下入小油管就可准确进入丢手内冲砂。自现场应用以来,对该工具进行了多次改进,取得了良好的效果,套管丢手内小油管冲砂扶正技术日臻成熟。
In order to enhance continuous-running efficiency,a special centralizer was developed and eliminated the tie back sting,and one trip was needed for the performance of sand washing by slim pipe.After several applications on site,the special centralizer tool has been improved for reliability and safety.
