Research On The Sedimentary Microfacies In Chengshen 5 Area Of Wangfu Area Denglouku Formation Of Bin Country

In this paper, using a variety of geology, and combining previous research results, the comprehensive analysis of logging, logging and seismic data, the stratigraphic division, the library’s building group in the study area is divided into three period of six groups, and analyzes the characteristics of sand strata distribution.Based on single well core and sand body vertical combination analysis of denglouku group is given priority to with the braided river delta sedimentary, lake facies, provenance direction from northeast to southwest, the development of three subfacies, braided river delta plain subfacies, braided river delta front subfacies, coastal and shallow lake facies. Braided river delta plain is further divided into braided distributary channel and the sedimentary microfacies, braided river delta front can be further divided into underwater distributary channel, underwater distributary channel, mouth bar microfacies.According to the single well facies analysis, the union well profile phase analysis,seismic attribute analysis, sandstone thickness distribution characteristics and analysis of sand ground than the denglouku group in the study area is discussed sedimentary facies belt distribution characteristics and sedimentary evolution characteristics. Also effect on structure,geomorphology, climate, sediment supply and so on to the control action of sedimentary are analyzed and studied.Finally, this paper also studied the relation of sedimentary micro facies oil gas,denglouku group can be used as a favorable oil and gas reservoir, and the denglouku group porosity and permeability of reservoir lithology, combined, according to oil and gas production Wells that braided river channel is the most favorable reservoir facies belt.
