仿真模型在剩余油研究中的应用综述

据统计，当今世界上油气开采储量的四分之三以上来自对现有油气藏管理的改善，而仅有不到四分之一来自新油气藏的发现，所以，提高己开发油气藏产量及提高油气采收率是当务之急，而对剩余油的研究则是其中的关键。地下储集体难以直接认识，而且其岩石物性、温压场、流体性质等千差万别，实验室研究不能准确反映地下情况。应用仿真模型来模拟剩余油的形成与分布，可以更直观地展现剩余油在地下的空间分布及演化规律，从而为剩余油的开发提供更为准确的资料。

Review on simulation model in the research of the remaining oil

According to statistics,in the world of today,more than three quarters of the oil and gas come from the management improving for hydrocarbon-bearing pool in existence,while less than one quarter comes from the discover of the fresh oil and gas pool.So the urgent matter of the moment is to increase the output of the exploitation hydrocarbon-bearing pool and to increase the rate of the oil and gas recovery,and the key is to study the remaining oil.The reservoir rocks underground are hard to directly be known.The property such as the physical properties of the rocks,the thermo baric field and the fluid property is significantly different,and the laboratory study can not exactly reflect the subsurface picture.Using the simulation model to simulate formation and the distribution of the remaining oil,this can intuitively show the spatial distribution and the evolution law of the remaining oil underground,and supply more reliable materials for the developing of the remaining oil.
