摘　　要：地震属性技术是剩余油预测的主要手段之一,基本原理是利用不同流体的地震响应差异进行流体识别。在长期开发油田中,注水冲刷作用会造成储层物性发生局部变化,降低了常规地震属性技术的油气预测精度。经研究发现:长期开发活动会导致中高渗储层渗透率增加,含水率上升,使得地下流体活动性增强,由于剩余油主要集中在注水波及程度较小或未波及的层段,对应的流体活动性相对较弱,应用流体活动性属性可以定性预测长期开发油田剩余油分布规律。实例分析表明,预测结果与钻井生产动态吻合率较高,可为油田开发方案调整提供参考。Seismic attribute is one of the main methods forremaining oilprediction. The basic principle is to use the differentseismic responsesof fluids for fluid identification. In the development oilfield,injectionnot only changes the fluid properties,but also changes the reservoir properties. Thus,we cannot ensure the precision of hydrocarbon detection with conventional seismic attributes. Through studying,this paperconsiders that developing activitycan enhance the mobility of the fluid. In contrast,the mobility of the fluid for the reservoir remainingoil is low.Therefore,using fluid mobility attribute,we can qualitativelydescribethe distribution of remaining oil indevelopment oilfield. Example shows that the predicted results match with the drilling production. And the results can be used for adjusting the development plan of oilfield.
