摘　　要：华北油田裂缝性灰岩油藏的油井堵水 ,无论是应用规模、施工井次 ,还是增油减水效果 ,在中国陆上油田都是名列前茅的 ,油藏不同时期的堵水技术值得其他油田借鉴。本文就华北油田裂缝性灰岩油藏中低含水阶段、中高含水阶段、高含水阶段和高含水后期开发阶段的油井化学堵水基本模式进行了总结论述。多年来的堵水实践表明 ,油井堵水是调整产液剖面、改善油藏内部裂缝系统和孔隙介质的油水渗流状况 ,提高油井产量和油藏开发水平必不可少的重要措施之一。The water shutoff practices on fractured reservoirs in Huabei Oilfield, not only its size, but also its constructed wells, result of oil increasement and water cut down are high valuable to be learned from,so the basic modes of chemical plugging used in different development stages, lower, middle and high water content stages, are summarized in this paper. The practices of waterflooding shows, the water shutoff techniques for wells are an important measures to adjust liquid production profile, improve the oil/water seepage between internal fissures system and porous medium, and increase the oil wells' production.
