Facies Evolution and Distribution of Subaqueous Fans Complex in Biyang Sag, Eastern China

Abstract:

Hetaoyuan formation of Palaeogene in Biyang sag experienced the process of sedimentation during the main depressing period. Lithological traps were formed by the Sandstone-conglomerate bodies as favorite targets for oil and gas exploration in the southeast of Biyang sag. In this study, seismic profile, cores and well loggings as main data are used to analyze the micro-facies of subaqueous fan complex system. Methods such as Phasing concertion, spectrum decomposition, and strata slice play important roles in the study of facies evolution and distribution in high-resolution sequence framework of the upper member of the third Hetaoyuan formation. Subsequently, All of the coarse-grained turbid sandstone and the distributary channels sediments are potential reservoirs for oil and gas storage.
