根据尚家油田尚94圈闭油气空间分布特征、油气成藏时期与断裂活动时期匹配关系，及原油生物标志化合物特征对比结果证实，尚家油田葡萄花油层原油不是尚家油田扶余、杨大城子油层原油通过断裂垂向运移注入的结果。钻井资料分析证实，尚家油田葡萄花油层的砂体虽然厚度小，但分布范围大，尚家油田葡萄花油层的原油是三肇凹陷青山口组源岩生成的油通过断裂沟通的砂体侧向运移至该区而成藏的。控制尚家油田葡萄花油层原油侧向运移聚集成藏的关键因素是断裂与砂体的组合形式：同向断层与砂体组合有利于油气进行长距离侧向运移；反向断层与砂体组合不利于油气的侧向运移，但利于形成断层遮挡圈闭，使油能够聚集起来。流体势场的空间分布同时控制着尚家油田葡萄花油层原油侧向运移及聚集的部位。

According to oil and gas spatial distribution characteristics of Shang 9 4 trap in Shangjia oilfield , relationship between temporal matching of hydrocarbon accumulation and fault activity , comparison results of crude oil biomarker , it is show n that the crude oil of Putaohua reservoir in Shangjia oilfield was not injected from Fuyu Yangdachengzi oil layers through the fracture by vertical migration .Based on drilling data ,sandbodies of Putaohua oil layer in Shangjia oilfield distributed widely but the thickness was thin .Under the control of faults ,the sandbody continuity became poor .Oil from K2 qn1 source rocks in Sanzhao depression transported laterally into Putaohua layer in Shangjia oilfield through sands connected by fractures .Combination styles of fracture and sandbodies are the key factors to control oil migrate laterally and accumulate in Putaohua layer of Shangjia oilfield .The combination of synthetic faults and sand is favorable for oil and gas for long-distance lateral migration , w hile the combination of antithetic fault and sand is against to lateral migration but is favorable to form screened traps and accumulate oil .Meanwhile ,the spatial distribution of fluid potential field also controls the lateral migration and oil gathering sites in Putaohua reservoir of Shangjia oilfield .
