Abstract
On the basis of the previous studies on key wells,sedimentary microfacies analysis of the third members of Hetaoyuan formation (H3 member formation) in southern Biyang Depression are studied. Its plain facies made from debris flow deposit,upper-water distributary channel and inbank flow deposit,and the upper-river channel deposit is better. Subfacies of frontal fan delta mainly includes debris flow deposit,subwater distributary channel deposit,distributary mouth bar and subwater distributary channel. The mood of frontal fan delta is made of deep gray and black gray mudstone,sandy mudstone,siltstone and so on.
