摘要:
泵送橋塞+ 射孔聯作分段壓裂近年來在國內外頁巖氣藏及致密氣藏開發中廣泛應用。在頁巖氣水平井泵送橋塞射孔聯作分段壓裂實踐中遇到了泵送橋塞因壓力高而不能泵送、橋塞坐封不丟手、橋塞坐封時電纜不點火、電纜點火后橋塞不坐封、射孔槍不響或2 簇射孔只射1 簇、連續油管射孔意外丟手等各種問題。針對所出現的問題進行原因分析,制定了防范措施和解決方案,現場實施后各頁巖氣井水平井段的壓裂改造施工得以完成,所取得的經驗和教訓可供今后同類井施工借鑒和參考。
Abstract:
In recent years, the pumping bridge plug and clustering perforation technique has been widely used in staged fracturing of shale gas and tight gas reservoirs at home and abroad. In practical operations in horizontal shale gas wells, various problems have been found, such as failed pumping or release of pumping bridge plug due to high pressure, plug setting without cable igniting, plug not set after cable igniting, dumb shooting of the perforating gun or only 1 of 2 clusters shot, and accidental release in coiled tubing perforating. Based on cause analysis for these problems, appropriate preventive measures and solutions are proposed. They have been applied practically to facilitate the fracturing treatment of horizontal shale gas wells. The experiences and lessons thereof will be meaningful references for staged fracturing operations in similar wells.
