| 摘 要： | 响水砂体是一出露比较完整的中生代的曲流河河道沉积。通过大断面写实的研究方法，运用沉积体系分析、层序地层分析、砂体内部沉积构成分析等方法，比较细致地划分了砂体内部成因单元和储层岩性相，从成因上研究了影响油气运移的沉积因素。通过砂体断面上一定间距的比较均匀的采样，并根据测试成果编图，展示了各种孔沙参数在空间的变化特点及其与各种界面、沉积水动力能量的联系，并依此总结曲流河点坝渗透率的分布模式。

| Abstract: | Sand body in Xiangshui is a kind of complete channel sediments in the Mesozoic meanderingstream course. Methods of large scale profile study in field used in analysis of sedimentary seriesand stratigraphic sequence, inner sedimentary constitution of sand body have been used for classifying the inner genetic units and reservior beds in detail. According to the genesis of the sandbody, the sedimentary factors that effected oil-gas migration have been studied. Based on sampling on the section of sand body at fixed intervals, compilation of measured results displayed thechangeable characteristics of permeability coefficient of various pores in space, the relationships toother interfaces and sedimentary hydrodynamic energy. Finaly, the distribution pattern of pointbar permeability in the meandering stream course is concluded in this paper. |
