By analyzing the drill core��well logging and seismic profile in Suotu area of Changling sag��Qingshankou Formation sedimentary microfacies and characteristics of sand body distribution in this area are studied�� The result indicated that the Gaotaizi oil layer in Suotu oil field was mainly the delta deposit; the Qingshankou reservoir can be divided into the delta plain subfacies deposition and the delta front subfacies deposition��which developed in distributary channel microfacies��interdistributary thin layer granulated microfacies��underwater distributary channel microfacies and underwater interdistributary thin layer granulated microfacies�� In objective layers��GI1 and GIV2 layers are poorly developed sandstone��but GI2 and GIV1 layers are well developed sandstone in a larger-area lamellar distribution pattern��
