Abstract
Based on the data of seism, logging and core, using principles and methods of sedimentology and seismic stratigrphy, this paper clarifys the microfacies characteristics of No.1 section of Qingshankou Formation, Taikang area of north Songliao basin. Deep lake and semi-deep lake subfacies are dominant in this area, which is featured by thick dark mudstone. There are lens-like sandstone bodies caused by sediments gravity flow developed in it. Delta developed in the west part of the studied area, sinuosity river delta developed in northwest part, and braid river delta developed in southwest part.
