摘要：Based on the analysis of core and well logging data, this paper analyzes the Quansan and Quansi sections in the Da-anbei area, the south of Songliao basin, to confirm sedimentary environment and establish corresponding logging facies model. After identifying each single well facies, the sedimentary microfacies distribution map of Da-anbei oil field was drawn, and the sedimentary evolution law of the area was established. The research indicates that, in the Da-anbei, the Quansan and Quansi sections successively developed the (high-energy) far-shore delta distributary plain, (low-energy) far-shore delta plain, nearshore delta plain, lake and shore interactive sedimentary area and the delta front sedimentary area.
