Sedimentary Characteristics of Fuyu Oil Layer in the Southern Fuxin Uplift of Songliao Basin

Abstract:

Based on 22 well cores and logging data of nearly 800 well, sedimentary characteristics of Fuyu oil layer in the southern Fuxin uplift was analyzed. It is shown that types of sandstone in the Fuyu oil layer are main feldspathic litharenite, debris arkose and minor litharenite. Granularity probability curve is displayed as a typical of two-stage or three-stage. A large number of parallel bedding, one-way oblique bedding, small-scale cross bedding, the bottom scour structure and syngenetic deformation structure can be seen in the Fuyu oil layer. Mudstone color is main fuchsia, grey purple massive mudstone and gray-green, gray, dark gray massive mudstone. Combined with the analysis of the sedimentary facies sign, Fuyu oil layer in the southern Fuxin uplift is large fluvial-dominated shallow water delta deposition. The skeletal sand bodies in the delta system are distributary channelsand bodies that are large, dense, narrow strip, continuous distribution. The overall is south-southwest trending. Sand body is continuous and far underwater extension until it disappears into thin sandsheet. multi-branch fluvial-dominated ribbon-like bodies are formed.
