| 摘 要： | 骨架砂体是沉积盆地内发育的同沉积输导体系。通过重点解剖东营凹陷南坡东段沙三段中、上亚段三角洲骨架砂体及沙二段河流相骨架砂体各静态地质要素发育特征,与油气显示特征相结合,发现砂体厚度、顶面形态与油气显示关系不明显;而砂体产状、物性与油气显示关系较好,砂体的产状和油气运移动力之一的浮力有关,而物性则与油气运移的毛细管阻力有关。倾角越大、物性越好,油气显示越丰富。因此确定产状、物性是影响砂体输导性能的主控因素,产状和物性的耦合控制了油气的优势运移路径。

| Abstract: | Framework sand body is the syn-sedimentary conducting system developed in the sedimentary basins.By researching development characteristics of static geologic factors of the framework sand bodies of mid-Es3,upper-Es3 delta and Es2 fluvial facies in the east part of the southern slope in Dongying Sag,sandstone thickness,the depth of superface has not obvious relation with oil-gas shows,but sandstone attitude and physical property has obvious relation with oil-gas shows,sandstone attitude is related to buoyan... |
