Based on the technologies of thin section identification, particle size analysis, core observation, logging analysis and physical property analysis, this paper studied the reservoir petrology characteristics, sedimentary structure characteristics, logging facies characteristics, physical properties and oil-bearing properties in in Yushulin-Zhaozhou area of Songliao Basin. The results show that the Putaohua reservoir in Yushulin-Zhaozhou area is fluvial delta facies, which can be further divided into eight microfacies, including distributary channel, natural levee, crevasse splay, interdistributary bay, subaqueous distributary channel, subaqueous interdistributary bay, frontal sheet sand and predelta mud. According to the analysis of the vertical sequence of single well, sedimentary microfacies and the relation between reservoir oil-bearing properties and microfacies types, it is believed that Putaohua reservoir experienced early base level falling and later base level ascending evolution, and microfacies types control the reservoir oil-bearing properties. This research result can provide technical support for the further efficient exploration and development in this area.
