[Abstract]:The Shenusi area is located at the junction of Cangdong Sag and Nanpi Sag in the Bohai Bay basin, Cangxian uplift in the west, Anchorage shape in the east and Gongdian structural belt in the east, and the west and east in the Cangdong fault and Xuxi fault respectively. It is a compound oil and gas accumulation area with the Kongdian formation as the main source rock and reservoir, and the second member of the Kongdian formation as the main exploration stratum. The exploration level in this area is relatively low and the oil and gas resources are not well proved. Sedimentary facies are one of the key factors which need to be further studied. Based on the above reasons, the Shenusi area of Cangdong-Nanpi depression is selected as the study area, the second member of the Kongdian formation is taken as the study horizon, and the sedimentary facies characteristics are further systematically studied by using the theories of seismic stratigraphy, sequence stratigraphy and sedimentology. The spatial distribution of the sedimentary system is revealed, and the sedimentary evolution of the second member of the Kongdian formation in the study area is summarized. The sedimentary evolution is guided by sequence stratigraphy and combined with earthquakes. The regional sequence interface of the second member of the Kongdian formation in the Shenusi area was identified and the regional sequence stratigraphic framework was established by comprehensive interpretation of the logging and lithologic data. Finally, the second member of the Kongdian formation is divided into two third-order sequences, two third-order sequences are the lower part of the second member of the Kongdian formation and the upper part of the second member of the Kongdian formation. The lower part of the Kongdian formation corresponds to the 3Q4 reservoir formation of the second member of the Kongdian formation, and the upper part of the second member of the Kongdian formation corresponds to that of the second member of the second stage of the Kongdian formation. (2) the lithologic facies, lithologic combination types and logging facies of the second member of the Kongdian formation in the Shennusi area are studied. Combined with regional geological background data, it is proved that there are braided river delta facies, lacustrine facies, far shore underwater fan facies and regional geological background in the second member of Kongdian formation in this area. Based on the analysis of sedimentary association wells in the main section of the second member of the Kongdian formation in the Shenuesi area, Cangdong to Nanpi depression, combined with the plane distribution characteristics of seismic attributes and the sandstone percent content data, The horizontal distribution of sand bodies in the second member of the Kongdian formation in the Shenusi area is analyzed. Finally, the planar distribution of sedimentary facies of the second member of the Kongdian formation in the Shennusi area is obtained. By comparing and summarizing the distribution of sedimentary microfacies in the second member of Kongdian formation in Shenusi area, the sedimentary evolution characteristics of the second member of Kongdian formation in the study area are obtained.
