摘要
In this paper, the authors have observed 15 cores. They have analyzed the petrology characters, sedimentary structures, biological fossils of the Chang 8-6 oil formations of Triassic Yanchang Formation in the Huanxian area. All the results suggest that in Chang 6 develops front-delta facies; in Chang 7 develops deep lake to half deep lake facies and turbidite fan and in Chang 8 develops prodelta facies. The front-delta facies is mainly distributed over the southwest of the area and the turbidite fan is mainly distributed over the eastern of the area.
