石油成藏的2个物理模型
|
摘要
为了研究松辽盆地扶余油层上生下储及叠状单砂体中石油聚集成藏的原理,利用实际油藏资料,从油气藏聚集形成原理入手,对上生下储及不同储层间形成的油气分异现象进行研究。研究结果表明:石油从生油岩排出到储集层,在构造运动期间,以断层为通道,油与水一同在重力的作用下从上部的储集层运移至下部的储集层,这种运移模式称之为重力涌流模型,到下部地层后又重新分异,以游离相沿通道向上运移及在圈闭中积聚;油气藏中石油、天然气与水不仅在同一储层中分异,也可以在上下两个砂体间通过断层(裂缝)连通形成分异系统,称之为异储分异物理模型。重力涌流和异储分异系统成藏原理物理模型,可以有效地指导油气勘探。
In order to research the principle of the hydrocarbon accumulation for the "source rock above reservoir"association and superimposed single sandbody in Fuyu oil layers in Songliao Basin,with the help of the actual oil reservoir data and in terms of the principle of the hydrocarbon accumulation,the petroleum differentiation phenomena presented for the "source rock above reservoir"association and among the different reservoirs were studied. The research achievements show that the oil discharges from the source rock to the reservoirs,in the period of the structural activities,taking the faults as the channels,under the mutual action of the gravity,the oil and water migrate from the upper reservoirs to the lower ones,this kind of the migration mode is called the gravity surge flow mode,and then re-differentiate in the lower formations,finally migrate upward in the form of the free phase and accumulate in the traps; in the hydrocarbon reservoirs,the oil,gas and water not only differentiate within the same reservoir,but form the differentiation system with the help of the connection of the faults( fractures) between the two sandbodies,this is named different-reservoir differentiation physical mode. The gravity surge flow and the reservoiraccumulating principle of different-reservoir differentiation system modes can effectively guide the petroleum exploration.
