Abstract

Based on the coring and logging data, the sedimentary facies in ZaoⅡand Ⅲ reservoirs of Guan 162 fault block in Dagang Oilfield are analyzed. The result indicates that Guan 162 fault block is mainly composed of braided river facies. The main microfacies are braided channel, interchannel beach, fluviatile flood-plain and flood plain. The plane distribution and evolution of the sedimentary microfacies are studied. Combining with the statistical analysis of the petrophysical data, it is considered that the braided channel sand body is the favorable facies belt in the study area.

Key words： high resolution sequence; lithofacies and paleogeography; paleosalinity; Chang 6 member; Jiyuan area
