摘要: 本文运用高分辨率层序地层学理论,对镇泾地区延长组长8油组储集砂短期基准面叠加样式以及储层非均质性特征进行分析,建立了6种不同的非均质模式;探讨了不同级别的基准面旋回对储层非均质性特征的控制作用,短期旋回控制了储层的层内非均质性特征,中长期旋回控制了储层的层间非均质性特征。

Abstract: The present paper deals, in the light of high-resolution sequence stratigraphy, with the stacking patterns of the short-term base-level cycles and the heterogeneity of the reservoir sandstones from the 8th oil reservoirs in the Zhenjing region, Ordos Basin. Six heterogeneity models are then constructed. The short-term base-level cycles have the dominant impact on the intraformational heterogeneity while the medium-and long-term cycles on the interformational heterogeneity of the reservoir sandstones.
