Several subaqueous alluvial fans are developed along the footwall of the northern boundary fault zone—the Daxing fault of the Langgu sag, Bohai Bay Basin, North China. A distinct feature is the significant difference in hydrocarbon enrichment between neighboring wells drilled in the same sedimentary facies. This paper analyses the controlling factors for hydrocarbon accumulation of subaqueous alluvial fan in the Caiyu field, north of the Langgu sag. Based on reprocessed seismic data and using Jason inversion method, the contrast of cross-well correlation panel was established and a reservoir type model was build-up; reservoir heterogeneity was interpreted from inversion impedance data. The result shows six conglomeratic bodies in this fan, which are stacked vertically and laterally. The lithofacies is the key controlling factor for the hydrocarbon accumulation, and diagenesis and tectonic stresses also play important roles in the hydrocarbon enrichment.
