摘　　要：有效预测井间夹层展布,对指导剩余油挖潜、提高油田采收率具有重要意义。以A油田Ed2Ⅲ31小层为例,在等时地层格架控制下,应用随机建模方法,在单井相分析成果建立的平面和垂向沉积微相分布趋势约束下,有效预测了该小层内多期沉积微相的展布,进而揭示了泥质夹层的空间分布;应用该研究成果,实施了一批挖潜措施,提高了单井产能。Effective prediction of interwell interlayer distribution is of great significance for remaining oil tapping and enhanced oil recovery.By taking Ed2Ⅲ31 sub-layer of A oilfield as an example,under the control of the isochronous stratigraphic framework,by application of the stochastic modeling method,under the constraints of plane and vertical distribution of sedimentary microfacies based on the single well facies analysis results,multiple-period of sedimentary microfacies distribution of the sub-layer has been effectively predicted,and it reveals the multi-stage sedimentary microfacies distribution and then spatial distribution of argillaceous interlayer.Through application of the research results,a number of exploration tapping measures have been carried out and it improves the single well production capacity.
