松辽盆地南部嫩江组(黑帝庙油层)发现多种类型油气藏。但是,沉积相研究尤其是精细微相研究非常缺乏,影响下一步油气勘探。为查明黑帝庙油层沉积相类型,搞清各探区沉积模式及砂岩分布特征,以沉积学理论为指导,运用钻井、测井、录井及开发井资料开展沉积微相研究,认为黑帝庙油层主要发育三角洲前缘亚相,主要有2种有利微相类型—水下分流河道与席状砂,明确松南黑帝庙油层砂岩特征和相模式控制下岩性油藏类型,为勘探部署提供科学依据。
Various types of reservoirs have been discovered in the Nenjiang Formation (Heidimu Formation) in the southern Songliao Basin. However, sedimentary facies research, especially the study of fine microfacies, is very scarce, affecting the next step of oil and gas exploration. In order to ascertain the types of sedimentary facies in Heidimiao reservoir and to find out the sedimentary model and the distribution characteristics of sandstone in the exploration area, the sedimentary microfacies study on sedimentary microfacies based on sedimentology theory and drilling, well logging, well logging and development well data There are two favorable facies facies submarine facies in the Diliu reservoir, which are two favorable microfacies: underwater distributary channel and sand-like sand. The characteristics of sandstone in Heidimiao reservoir in Songnan and lithologic reservoir types controlled by facies model are defined. Provide a scientific basis for deployment.
