摘　　要：舍女寺油田孔二段油藏为孔南地区低渗透油藏的典型代表,其整体构造形态为北东东向的背斜构造,沉积背景为三角洲前缘亚相。目前油田构造高部位及沉积有利位置含油区块均已开发,剩余的未动用储量处于构造低部位或者沉积边缘地区。多年来由于储层物性差,储层横向变化快及地震资料品质差等因素一直制约了储量的动用。本研究在对研究区地质特征进行精细研究基础之上,应用地震资料拓频处理、地震资料正演模拟、含油砂体敏感参数优选及测井约束反演等技术和手段,对舍女寺油田女91-女13断块优势储层进行了预测。优选了有利建产区域,实施后与预测成果符合程度高,取得了理想效果。The low permeability reservoir of two section of Kongdian FM in Shenvsi oil field is typical representative of low permeability reservoir in the south area. It is a structure of the North East to the East, and the sedimentary background is the delta front sub facies. The high position of structural and the favorable position of the oil field have been developed, and the remaining undevelopd reserves are in the lower part of the structure or the marginal area. For many years, due to the poor reservoir physical property, the lateral variation of reservoir and the poor quali- ty of seismic data have restricted the development of reserves. Therefore this study based on the geological character- istics of the study area, using seismic data frequency broadening processing, seismic forward modeling, oil - bearing sand body sensitive parameters optimization and log constrained inversion technology and means to analysis reservoir distribution characteristics. This method successfully predicted N91 -N13 fault block advanage reservoir, and optimization of favorable construction area. After the implementation, the results are consistent with the predicted results.
