稠油边底水油藏水平井堵水技术改进与试验

摘要

The edge and bottom water coning in the development of heavy oil horizontal wells leads to water production in oil wells, Because of the screen pipe completion, long well section and higher pressure at water bursting point, the water plugging effect in horizontal wells is not ideal. Therefore, based on characteristics of existing water plugging technologies, the mechanical water plugging method and chemical water plugging method were combined, and the field test was successful ,which can provide the technical reference for the development of horizontal wells in heavy oil reservoirs with edge and bottom water.%　　稠油水平井吞吐开发中边底水锥进导致油井出水，因筛管完井方式、井段长、出水点压力高等因素影响，已有的水平井堵水措施效果不理想，为此，在对比目前各种堵水技术的优缺点基础上，进行改进完善，将机械堵水、化学堵水有机组合应用，在现场试验中见到明显效果，为稠油边底水油藏水平井水侵治理提供了技术上的参考和借鉴。
