松南某区块扶余油层流以大型河相沉积为主,河道砂体叠置发育,砂地比通常在30%~70%,单砂层厚度一般为3~10 m,泥岩隔层1~20 m,砂岩叠置关系错综复杂,储层发育,但多数储层致密,非均质性强。本文主要针对扶余致密油气藏储层岩性油气藏的复杂性,利用地震资料开展储层预测研究,提高储层预测的纵向分辨率,开展河道砂体沉积模式及有效河道砂体的地震识别技术研究,探索有效储层及含油气性预测方法,进行储层精细描述和刻画。
The Fuyu oil layer flow in a block of Songnan mainly consists of large-scale river facies. The sand body of the channel is superimposed and developed. The sand area ratio is usually between 30% and 70%. The thickness of a single sand layer is generally 3 to 10 m, the mudstone interval is 1 to 20 m, Sandstone superimposed relationship is complex, reservoir development, but most of the reservoir dense, strong heterogeneity. This paper focuses on the complexity of lithologic reservoirs in Fuyu tight reservoirs, uses seismic data to conduct reservoir prediction studies, enhances the vertical resolution of reservoir prediction, carries out sedimentary models of channel sand bodies and effective seismic identification technology of channel sand bodies Research, explore effective reservoirs and oil and gas prediction methods, the reservoir fine description and characterization.
