准噶尔盆地腹部陆梁油田侏罗系—白垩系成藏模拟研究

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。

The simulation research of Jurassic-Cretaceous reservoir formation of Luliang oilfield in the abdomen of Junggar Basin

In order to further clarify the displacement pressure effect on the oil and gas distribution and accumulation process with fault transportation in Luliang oilfield based on the geology condition and accumulation and distribution characteristics of Luliang oilfield, experiment model was designed, and using physical simulation method to simulate the oil migration and accumulation process in fault conducting system. The experiment process and results showed that displacement pressure control the accumulation performance reservoir which are lateral configuration with fault in Luliang oilfield. The reservoirs, docking with fault and having low displacement pressure, have priority to accumulate and higher oil saturation. The reservoirs, docking with fault and having much higher displacement pressure, accumulate lately and have lower oil saturation. The reservoirs which are not docking with fault cant form oil and gas pool, no matter how high or low the displacement pressure is. The experiment process makes the accumulation process and distribution characteristics of Jurassic-Cretaceous reservoir to reappear in Luliang oilfield.
