摘要: 根据各种成岩作用发生的时间序列及其面孔率统计结果,恢复了储层在油气充注期的孔隙度分布情况,建立了砂岩层油气输导格架。以鄂尔多斯盆地陇东地区延长组为应用实例,利用基于该方法所建立的输导格架,模拟了油气运聚过程,油气分布预测的结果与目前探明油气区吻合,验证了该方法的可行性。进一步探讨了在建立输导格架时影响其精确性的两个重要因素。

Abstract: According to the investigation results of diagenetic sequences and the statistics data of plane porosities resulted from the main kinds of diagenesis,the porosity distribution of reservoir in the period of hydrocarbon migration was analyzed,and the hydrocarbon passage framework was established.As an application sample,the passage framework of Yanchang Formation in Ordos Basin was constructed by this method.On the basis of the constructed passage framework,the hydrocarbon migration process was simulated.The predicted distribution of hydrocarbon corresponded to the explored oilfields at present.Two influential factors affecting the construction accuracy of passage framework were discussed.

Key words: Ordos Basin, diagenetic sequence, hydrocarbon passage framework, hydrocarbon migration pathways, porosity, hydrocarbon prediction
