Title: Research on depositional characteristics of Shahezi formation in Western fault depression of North Songliao Basin
Abstract: Based on a large number of data of core, log and seism, and by the newest methods of sedimentology, this paper clarified the characteristics of sedimentology of Shahezi Formation in Western Fault Basins Belt of North Songliao Basin. There are fan delta depositional systems, lacustrine and lake-floor fan systems and also volcanic facies developed in the fault basins. Fan delta depositional system were developed along the margin fault; toward the basin, lacustrine system was developed, and deep lake facies were developed very well; and in the deep lake area near the fan delta, lake floor fan was developed. These kinds of characteristics of sedimentology reveal the favorable conditions of source rock, reservoir and seal rock and the favorable potential of oil and gas exploration.
