摘　　要：根据油田开发的需要,在高含水油田有必要开展油藏地球物理技术研究,横向上要精确识别和预测对剩余油富集具有遮挡作用的小断层、微幅度构造、砂体边界和岩性隔挡(如废弃河道),纵向上要精细预测控制剩余油丰度的砂体厚度和储层物性参数,重点解决河道边界预测和薄互层储层单砂体厚度预测精度问题。并结合高含水油田开发的需求,提出了关于发展油藏地球物理技术的发展方向。以大港油田港东一区一断块研究为例,说明了在高含水油田应用油藏地球物理技术的必要性和有效性。Based on the development of oilfield, the reservoir geophysics techniques is necessary to accurately recognize and predict some geology features in the oilfields with high water cut, including minor fauh, microstructure, frontier of sand body, lithologie barrier （abandoned channel）. Those geologic features have important shelter effect on enrichment of residual oil along the horizontal direction. The thickness of sand body and property of reservoir are the factors for controlling abundance of residual oil along the vertical direction. The reservoir geophysics techniques are proposed to enhance the prediction accuracy of channel edge and the thickness of single sand body to meet the requirement for development of oilfield with high water cut. Taking the first block of East-1 District in Dagang Oilfield as an example, it is proved to be necessary and effective for developing these techniques.
