Abstract

Abstract: Due to the poor understanding of favorable reservoir distribution and oil-water relationship in the top oil-gas-producing interval of the Badaowan Formation in the Wellblock Chepai 7, northwestern margin, the Junggar Basin, it is difficult to make progress in the evaluation of reservoir expansion. Based on logging, well testing and seismic data, the sedimentary facies and favorable reservoir distribution in the study area were carefully studied by means of sedimentary facies division, comparison of sand facies in continuous wells, seismic attribute analysis, seismic wave impedance inversion, stratigraphic slicing, etc. The results showed that there was fan prodelta sedimentary subfacies developed on the top of the Badaowan Formation, three relatively independent fan delta underwater distributary channel sand facies developed on the top of the Badaowan Formation from northwest to southeast, two of which were favorable oil and gas reservoirs. The sand facies of Wells Che 5027 and 369 were two independent disconnected sand facies. The sand facies of Well Che 5027 and Well Chepai 7 could be expanded in direction of southeast, southeast and northeast respectively. The study results play a guiding role in the further development of the Badaowan Formation in the study area.

Key words: reservoir prediction, wave impedance inversion, seismic attribute analysis, top of Badaowan Formation, Wellblock Chepai 7, Junggar Basin
