摘 要：1 Introduction Based on systematical analysis of the abnormal pressure distribution obtained by equilibrium depth method(Chen and Luo,1983)in the lower assemblage of Yanchang formation in the middle area of western Ordos Basin,combined with the distribution patterns of hydrocarbon reservoir discovered in the researched region,the relationship between abnormal pressure and distributions of hydrocarbon reservoir discovered and also hydrocarbon migration&accumulation is disclosured.
