油气运聚成藏机理实验模拟研究进展

Advances in Experimental Simulation of Oil and Gas Migration and Accumulation Mechanism

实验模拟是油气二次运移和聚集理论发展的起始点,在描述油气运聚机理和过程方面始终是不可替代的手段。随着实验模型种类的多样化,实验模拟研究的内容越来越多。但由于检测手段、边界效应、设备微渗漏和许多地质现象在实验模型中构建不合理等因素的影响,许多实验结果难以反推到地下。因此检测手段的改进、边界效应影响的减小和自动成图技术的发展是今后实验装置设计的发展方向。岩性油气藏成藏机理、断裂控藏、晚期构造运动对早期油气的改造作用和非常规油气藏运聚成藏机理仍然是未来实验模拟的主题,但必须从实际地质解剖出发,论证实验的可行性,保证实验结果能够应用于地下条件。

Physical simulation is the development beginning and one of the important ways in depicting the mechanism and process of oil and gas migration and accumulation. With more kinds of experimental models,more contents are included in physical simulation. Because of the influence of many factors,such as detecting means,boundary effects,delicacy seepage of instruments,irrational geology phenomena in the experimental model,many experimental results couldn＇t apply in subsurface conditions. So it＇s the main future aspect that we better the detecting means and decrease the boundary effects and developing the automatic forming charts. In future,physical simulation main thesis include many aspects：such as lithological reservoir,mechanism of faults＇ controlling the migration and accumulation of oil and gas,Later tectonic movement reconstructing the early oil reservoir,mechanism of migration and accumulation of unconventional oil and gas. Based on the actual reservoir analysis ,we should discuss the experimental feasibility so that it was applied in the subsurface conditions.
