摘　　要：魏岗油田为高凝复杂断块油田,目前已经进入高含水后期开发阶段,地下剩余油呈"整体高度分散、局部相对富集"的状态。通过应用四区断块的储层建模、微构造精细解释结果,开展低序级断层的封闭性认识,结合历史井网、水驱前缘监测资料、新钻油水井资料,搞清剩余油分布规律,在剩余油富集部位部署侧钻井及综合调整措施的实施,有效地挖掘剩余油,提高断块油田开发效果。Weigang Oilfield is a higher curdled and complicated fault block oilfield. After 30 years exploitation, it has entered the late recovery stage. Remaining oil becomes wide diversified totally and relatively rich partly. Through application of four-block area of the reservoir modeling and micro-structure explanation and study analysis micro-fault closeness, combined with the historical well pattern, water injection monitoring, the newly drilled oil wells information, the remaining oil was predicted accurately. As the remaining oil distribution is determined, side-tracking and other comprehensive workover were carried out in rich oil area, the remaining oil was effectively developed and the exploitation was improved in fault block reservoir.
