摘要
安塞油田王窑区延长组长611层储层为湖相三角洲前缘砂体,沉积相控制储层物性及非均质性。通过对区储层层内韵律性、层间差异性和平面上砂体连续性的研究,揭示储层的宏观非均质性特,认为鄂尔多斯盆地王窑地区储层长611层段平面非均质性较强,层间非均质性较强,层内非均质性严重。
Chang -61^1 reservoir is a depositional sandbody of the lake -front facies in Wangyao tract, Ansai oil field, the sedimentary facies control physical property and heterogeneity of reservoir. Based on the analyzing of the reservoir of internal rhythmicity, inter/ayer differences, sandbody continuity in plane, it reveals the macroscopic heterogeneity characteristic of the reservoir. It draws a conclusion that the characteristic of the Chang 61^1 reservoir has strong plane heterogeneity, strong interbedded heterogeneity and bad inlayer heterogeneity in Wangyao tract, Ansai oil field, Ordos Basin.
