摘要(Abstract)：

为了认清太东地区葡萄花油层的油气成藏规律,采用油分布与成藏条件叠合的方法,对油成藏主控因素和模式进行了分析。研究认为:太东地区葡萄花油藏主要受到圈闭、储层及断裂侧向遮挡3个因素的控制,即北北东向和近南北向断裂为油聚集提供了有效圈闭,河道砂和主体席状砂为油聚集提供了有利的储集体,断层侧向封闭性强弱控制油富集程度;葡萄花油成藏模式为三肇凹陷青一段源岩生成的油气沿断裂运移至上覆葡萄花油层中,然后沿北北西向席状砂体侧向运移,被太东地区北北东向或近南北向的反向断裂遮挡,形成断层一岩性油藏或断块油藏。
In order to make clear of the petroleum accumulation and reservoir forming laws for Putaohua oil layers in Taidong area,with the help of the matching method between the oil distribution and accumulation & reservoirforming conditions,the main controlling factors and models of the oil accumulation and reservoir forming are analyzed.The studies show that the oil layers are mainly controlled by the following three factors:traps,reservoirs and fault lateral screen i.e.NNE and near SN faults provide favorable traps for the oil accumulation;the channel and main sheet sands present the favorite reservoirs for the accumulation;the strong and weak fault lateral sealing abilities control the oil accumulated degree;the models for the oil accumulation and reservoir forming is that the oil and gas from K_1 qn_1 sourcerock in Sanzhao Sag migrate along the faults up to the overlying Putaohua oil layers,and then migrate laterally along the NNW sand sheets and finally screened by NNE or near SN inverse faults in Taidong area.In the end,the petroleum accumulates and forms fault-lithology or fault block oil reservoirs.
