摘　　要：随着金湖凹陷勘探程度日益提高和勘探难度的不断加大,勘探目标也由热点地区转向低勘探地区的挖潜、突破。杨村断裂带上升盘邻近生油次凹,并有深大断裂沟通油气,成藏条件良好,勘探工作也逐渐引起重视。从油源、储盖组合、油气运聚、构造及成藏模式等方面对上升盘白垩系成藏条件进行研究,认为杨村断层的侧向封堵是上升盘能否成功的关键,上升盘北部构造带成藏条件最为优越。With the increasing degree and difficulty of exploration in Jinhu Depression,exploration targets have also shifted from hot spots to tapping potential and breakthroughs in low exploration areas.The uplifted side of Yangcun Fault-zone is adjacent to the subsag of oil-generating,and there are deep and large faults to communicate oil and gas.The accumulation conditions are good,and then exploration work has gradually attracted attention.From the aspects of oil source,reservoir-caprock assemblage,oil-gas migration and accumulation,structure,and accumulation model,this paper studies and analyzes the hydrocarbon accumulation conditions of the Cretaceous system in the uplifted side.It is considered that the lateral sealability of Yangcun Fault is the key to the success of the ascending plate.The northern tectonic belt has the most favorable reservoir forming conditions.
