A Distribution Regularity Study about Ternary Composite Expulsion of Residual Oil within the Third Grade of Reservoir Bed in the Northeast Massif of Lamadian, Heilongjiang, China

Abstract:

In the Northeast massif of La (Lamadian), it is going into the later exploit period with higher containing water in reservoir. In order to increase recovery efficiency, it is needed to discover a potential extract ability of residual oil. By studying the higher sub-layer II 1-18 in the northeast massif of Lamadian oil field this time, based on developing a carefully detailed reservoir description for that, in terms of resisting inter layer recognition in single well, depositional microfacies delineation, and reservoir features study, combined with dynamic data, control factors and distribution of residual oil in that region are analyzed and concluded. The result illustrated that the vertical rhythmic structure of reservoir is closely related to residual oil distribution, some different models of residual oil can be distinguished by rhythm; additionally, the planimetric position of residual oil is mainly controlled by depositional microfacies and reservoir features, planimetric heterogeneity, as well as inject-exploit relation.
