摘要
通过油气成藏条件分析,探讨了松辽盆地北部宋芳屯油田芳3区块葡萄花和扶杨油层的油气成藏特征与油气富集条件。分析认为,芳3区块的圈闭主要为断层圈闭、断层-岩性圈闭,成藏的关键控制因素是储集层上倾方向的断层遮挡。沟通葡萄花储集层与烃源岩的断层规模一般都比较大,而沟通扶杨油层与烃源岩的断层以小规模为主。烃源岩是青山口组泥岩,就研究区的油气富集来说,有利烃源岩主要位于研究区内及其附近,东部三肇凹陷主体部位烃源岩对研究区的贡献有限;葡萄花油层物性、油气运移条件明显好于扶杨油层。综合分析认为,葡萄花油层的油气富集潜力要高于扶杨油层。
By analysis of reservoir formation condition, the authors discussed the characteristics of oil pool formation and the condition of petroleum accumulation in the area Fang 3, Songfangtun Oilfield, north of Songliao basin. In this district, there are mainly fault traps and fault-lithology traps. The key control factor of reservoir generation is that the fault is located on the upper side of reservoir incline. The scale of the faults to communicate Putaohua reservoir with source rock is generally greater and that to communicate Fuyang reservoir with source rock is commonly smaller. The source rock is the mudstone of Qingshankou Formation, the advantaged source rock is located in or nearby the research area and there is not almost contribution of source rock in the main body of Sanzhao depression. The porosity and permeability of reservoir and oil migration condition in Putaohua oil layer are excelled to that Fuyang oil layer. It is thought that the petroleum potential in Putaohua oil layer is better than that in Fuyang oil layer by integrated analysis.
