摘要:
針對水平井壓裂時經常遇到的砂堵現象,通過研究連續油管內壓力損耗原理,建立了連續管摩阻計算模型,參考模型計算結果優選連續管,完善地面設備配置,形成一套連續油管水平井多簇滑套解堵工藝。利用該工藝可以在不起下井內管柱的情況下,實現油管或套管內解堵施工,工序簡單有效,作業效率高,同時可有效避免因堵塞壓力的突然釋放帶來的井控風險。該作業技術經吉林油田紅平57-**井現場試驗,成功實現解堵施工,為實現后續壓裂提供了保障。
Abstract:
In view of the sand plugging phenomenon in horizontal well fracturing,the friction calculation model of coiled tubing is established by studying the principle of the internal pressure loss in coiled tubing. The coiled tubing is optimized by the model calculation results so as to improve the ground equipment configuration and form a set of the multi-cluster sliding sleeve plug removal technology in coiled tubing horizontal well. This technology can be used to realize the plug removal construction in the oil pipe or casing without running and retrieving the inner pipe string,which is simple and effective. At the same time,the well control risk caused by sudden release of the plugging pressure can be avoided. This operation technology has been successfully implemented in the field test of Hongping 57-** well in Jilin oilfield and realized the plug removal construction,guaranteeing the subsequent fracturing.
