摘要

During the deposition of Fuyu oil-bearing combination in the lower part of north Songliao Basin, the continental sedimentation system mainly dominated by the fluvial-delta deposition was developed extensively. Based on the systematic data collection of core, logging, well logging and analysis and testing of Hetingwopu area, a comprehensive characteristic analysis for sedimentary microfacies, sandbody distribution and reservoir diagenesis in Fuyu oil layer is carried out. The results show that meandering river point bar, distributary channel and crevasse channel sand-bodies are mainly developed in Fuyu oil layer; the reservoir is at A sub-stage of late diagenesis; the genetic type and diagenesis of sand-bodies have an obvious controlling effect on the heterogeneity and oil-bearing properties of the reservoir.
