摘　　要：为了掌握剩余油分布规律,现场多采用渗饱-水驱曲线法和灰色关联法两种方法,并结合油藏动态、静态资料确定剩余油分布,但这两种方法的准确性及其适用性一直未得到验证。以石南21井区示踪剂监测井组为例,基于井组动、静态数据,通过渗饱-水驱曲线及灰色关联方法预测该井组剩余油分布,并将结果与该井组的示踪剂监测结果进行对比分析,从而验证了两种方法的准确性并确定其适用性。结果表明,上述两种方法预测剩余油分布的结果与示踪剂监测的结果较为一致,对于处于高含水期的低渗油藏具有一定的适用性。In order to understand and grasp the rule of remaining oil distribution, the field uses a variety of methods in the analysis and description of remaining oil distribution. Among these methods, permeability-saturation curve method and gray correlation method can be combined with the dynamic and static data to determine the remaining oil distribution conveniently and are widely used in the field. But the two methods＇ accuracy and applicability has not been validated. Therefore, this arti- cle, exemplified by the tracer monitoring well group of ShiNan 21 wellblock, based on the dynamic and static data, uses permeability-saturation curve method and gray correlation method to predict the remaining oil distribution of the well group, and analyzes the results with tracer monitoring results to verify the accuracy and determine the adaptability. The results show that the above two methods to forecast remaining oil distribution is consistent with the tracer monitoring results, and they have certain applicability for low permeability reservoir at high water cut stage.
