Abstract
Acoording to analysis of core samples and logging data,It is considered that that front-delta deposition is the main sedimentary system of Chang 6 oil-bearing formation in Hujianshan-Wuqi district.It includes four types of sedimentary microfacies which are underwater distributary channel,underwater distributary channel deposit,underwater natural levee deposit,underwater crevasse splay deposit. The underwater distributary channel is good reservoir ,and underwater distributary channel sand bodies are the direction of developing in this area. The sedimentary facies analysis is the key to study the sand body distribution,determining sedimentary facies correctly or not is affecting directly to understand sand distribution rule
