为明确陆梁油田储集层排驱压力对油气成藏及分布的影响作用,基于油田地质条件及成藏模式,设计实验模型,运用成藏物理模拟方法,模拟断层输导下的油气成藏过程,观察现象、分析结果,揭示了陆梁油田不同储盖组合成藏性能受排驱压力控制,即在注入一定压力下,与断层对接储集层排驱压力较小的储盖组合优先成藏,且含油饱和度较高;与断层对接排驱压力较大的储盖组合成藏较晚难度较大,含油饱和度较低。未与断层对接的储集层,无论其排驱压力大小,均难以成藏。物理模拟实验再现了陆梁油田侏罗系—白垩系成藏过程。
In order to clarify the effect of reservoir drainage pressure on reservoir formation and distribution in Luliang oilfield, based on the geological conditions and reservoir forming patterns of the oilfield, experimental models were designed and the reservoir physical simulation method was used to simulate the hydrocarbon accumulation The results show that the reservoir-forming performance of different reservoir-cap assemblages in Luliang Oilfield is controlled by the displacement pressure. That is, under the certain injection pressure, the reservoir-cap combination with less pressure on the reservoirs with fault-docking reservoirs has priority Reservoir with high oil saturation. It is more difficult and more oil-saturated for the reservoirs with relatively large pressure to be docked and paralleled with faults. Reservoirs that are not docked with faults are difficult to accumulate regardless of the pressure of their drainage. Physical simulation experiments reproduce the Luliang oilfield Jurassic - Cretaceous accumulation process.
