Abstract
Wucangbu is located at the midpiece of Yishan slope in ordos basin,whose western-leaning single slope is only 1 ° or so.In this paper,through a lot of logging and analysis tests,based on analyzing sedimentary characteristics,structure characteristics and petrology,favorable reservoirs were studied.The results show that favorable reservoirs are mainly in distributary channel sedimentary facies,secondly distributary bay sedimentary facies.
