摘要
松辽盆地北部下部含油组合扶余油层沉积时期,广泛发育了以河流、三角洲沉积为主的陆相沉积体系.在系统收集该盆地何廷窝堡地区岩心、录井、测井和分析化验等资料基础上,开展了针对扶余油层沉积微相、砂体展布及储层成岩作用特征综合分析,表明扶余油层主要发育有曲流河点坝、分流河道和决口水道砂体,储层处于晚成岩A亚期,砂体的成因类型和成岩作用对储层非均质性和含油性具有明显的控制作用.综合应用岩心、测井和地震储层预测资料,建立了非均质储层定量评价方法,为进一步揭示扶余油层储层发育的有利部位,指导勘探部署和储量评价提供了重要依据.
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. Meanwhile, a quantitative evaluation method for heterogeneous reservoirs is established using core, well logging and seismic data for reservoir prediction comprehensively. Thus, the important basis for revealing the favorable locations of developed reservoirs in Fuyu oil layer and guiding the exploration deployment and reserves evaluation is provided.
