| 摘 要： | 苏里格气田是鄂尔多斯盆地新近发现的最大整装气田,其产层主要是二叠系的盒8砂岩。该砂岩河道成因,具有厚度大、岩性均一的特征,其成分主要由石英构成。储层物性非常好,表现为中一高孔渗条件,含气性也好。砂岩含气后,泊松比明显下降,表现出地震纵波速度和地层密度的相应变化,这种变化有利于采用AVO方法进行砂岩含气性的检测。

| Abstract: | Sulige gasfield is a newly discovery in Ordos basin, its key pay layer is in He 8 sands of Permian. Genetically channel related, with thick and homogeneous qualities, it consists of quartz in bases. The sands performes fine petrophyics, mid to high porosity and permeability, mostly gas filled. Poisson's Ratio significantly decreases in sands while its gas saturation increases, so that seismic compressional velocity and density change correspondingly, which is advantageous for using AVO to detect gas in it. |
