Provenance direction research is an important part of the sedimentary facies research. The provenance direction is able to represent the direction of ancient water flow in the geological historical period. Furthermore, it is able to control the distribution range and the extensive trend of the sand body as well. Consequently, the analysis and research on the provenance direction plays an important role in the comprehensive analysis involving the sedimentary facies distribution, reservoir evaluation, as well as oil and gas accumulations. Combining the analysis on basin regional geological background, heavy mineral assemblages, the thickness of sandstone, and the distribution characteristics of sedimentary sand body with each other, the provenance analysis on Putaohua reservoir is comprehensively conducted in Daan regions along the river, Songliao Basin. The results show that the west part of Putaohua reservoir in Daan regions along the rivers greatly controlled by northwest provenance (north-west branch and north-west-west branch); in the meantime, Nanshanwan region is mainly affected by the northeast branch of northern provenance.
