稠油热采水平井插管堵水工艺应用及效果分析

摘要

For heavy oil thermal recovery horizontal wells in the aquifer rise,the conventional me-chanical closure process is difficult to adapt to the problem.The dual-packer intubation water shutoff process is adapted for heavy oil thermal recovery horizontal wells to solve mechanical wa-ter plugging problems of heavy oil thermal recovery of horizontal wells and realize the combina-tion of column anchor seat seal,releasing and injection and integration in one.A water shutoff technology column composition,working principle,technical parameters and characteristics are in-troduced.The practice test has proved that:the dual-packer intubation water shutoff technology realized the combination of column anchor Block seal,plugging,injection and integration,and the water shutoff in one.%针对稠油热采水平井含水上升而常规机械封堵工艺难以适应的问题，采用稠油热采水平井双封插管堵水工艺，解决稠油热采水平井的机械堵水问题，实现管柱锚定、坐封、丢手和注采一体化。介绍了堵水工艺管柱组成、工作原理、技术参数和特点。实践证明，双封插管堵水工艺管柱取得了明显的堵水效果。
