摘　　要：机械卡堵水技术在实际生产中应用越来越多,生产管柱因卡层出砂导致的砂卡管柱现象日趋严重,经常因砂卡造成管柱大修。研究一种新型分采举升工艺管柱技术,解决卡层出砂导致分采生产管柱砂卡的问题。关键技术是通过工艺管柱的优化设计及配套工具技术研制,在管柱发生砂卡时,通过上提管柱而解卡。如果上提管柱不能解卡,则可从安全释放装置处顺利释放,然后对井筒内管柱进行套洗冲砂,最后将井筒内剩余管柱依次捞出,避免油井进行大修作业。Mechanical technology for plugging water is widely used in the actual production,and sand stick caused by sand layer in production pipe string is becoming more and more serious,often leading to workover.Therefore,developing a new type of production pipe string technology to a-void the workover caused by sand stick is necessary,the key technology is the optimization design of the lifting process pipe string and matching tool technology development,when pipe string is stuck by sand in controlled layer,it is likely to be released by rising pipe string,if this solution fails,the pipe string can be released from the safety joint smoothly,then wash sand between pipe string and casing in wellbore,finally get the pipe string out of wellbore sequentially,avoiding the workover operation.
