Abstract

The Chang 7 oil reservoir set has great hydrocarbon potential inMaling area, Ordos Basin.With the development of oil and gas exploration, the exploration difficulty is increasingly growing in Chang 7 oil reservoir set. The accumulation mechanism of lithologic reservoir in tight sandstone gradually becomes the main difficulties for
exploration arrangement of Chang 7 oil reservoir set of Yanchang Formation in Ordos Basin. Based on study of the characteristics of source rocks, sedimentary facies, reservoir and structure, the characteristics and rules of reservoir distribution were summarized, and the main controlling factors for hydrocarbon accumulation and enrichment were analyzed. The result shows that Chang 7 oil reservoir set is mainly lithologic reservoir, turbidite facies is the main sedimentary type, and the hydrocarbon accumulation and enrichment is mainly controlled by source rocks, sedimentary facies and reservoir.
