| 摘 要： | 南襄盆地泌阳凹陷的形成和发展受控于南部2组深大断裂;优越的生油条件提供了丰富的油源,砂体发育,储集条件良好,有利的生储盖组合与多种圈闭模式配置关系良好,成藏条件十分优越。其隐蔽油气藏类型繁多,可划分为5类19种。平面上,受生油凹陷控制,呈环带状分布;纵向上,受温度、压力控制。其油气富集规律特点有:边界大断裂位移变换段是寻找大规模砂岩上倾尖灭油气藏的有利地区;继承性的沉积—构造斜坡是油气大规模运移的指向区,鼻状隆起是油气富集带;深凹区有利于寻找低位扇、白云岩油气藏和深盆油气藏;边界大断裂的两端受其几何样式影响,易形成滚动背斜油气藏。

| Abstract: | The Biyang Sag in the Nanxiang Basin is very favorable for hydrocarbon accumulation.Formation and development of the sag are controlled by 2 deep-large faults in the south.Superior oil generation conditions,abundant sediment resources,development of sand body,good reservoir conditions,good source-reservoir-cap rock assemblage and multiple trap model configurations are favorable for accumulation.Subtle oil and gas reservoirs can be divided into 5 major types and 19 subtypes.In plane,reservoirs locate in circles,controlled by source sag.Vertically,they are influenced by temperature and pressure.Displacement sections of large boundary faults are favorable for large-scale sandstone pinch out reservoir.Inherited sedimentary-tectonic slopes are the targets for large-scale hydrocarbon migration.Oil and gas us-ually accumulate in nose-like uplifts.Deep sags are favorable to find low system trace fans,dolomite oil and gas reservoirs and deep-basin oil and gas reservoirs.Controlled by geometrical patterns,rollover faults can be found at the 2 ends of boundary fault. |
