Abstract

Based on an analysis of well-log data and seismic profiles, the authors have identified the main sequence boundaries in the Bayan Qagan subbasin of the Eren basin, established the sequence stratigraphic framework of the subbasin and described the types of sedimentary facies and their plan distribution and constructed a sedimentary facies model of this half graben.According to the features of the source-reservoir-cap rock assemblage, the authors predict that:the Tengger Formation (sequence Ⅲ) and the first member of the Duhongmu Formation (sequence Ⅳ)are the favorable target zones for petroleum exploration, the fluvial sand bodies along the southern gentle slope and alluvial fan deposits along the northern steep slope are the favorable reservoir zones for hydrocarbon accumulation and the Da'erqi fault-block and Sanghe district are favorable blocks for hydrocarbon accumulation.
