Fracture system and Hydrocarbon Accumulation in Wangji-Xinzhuang Block in Biyang Depression

Based on studies on the relationship between the sizes of faults, continuity and hydrocarbon accumulation, it is pointed out that the development of the NE main faults control the distribution of reservoirs, and that the arrangement relationship between sandbody distribution direction and the strike of faults control the enrichment of hydrocarboa Both the Well B259 and Biqian 57 blockbased on these understandings are very successful.
