随机建模方法在剩余油分布及挖潜中的应用

The Application of Random Modeling in Residual Oil Distribution and Increment of Potential Exploitation Resource

应用储层地质随机建模方法，对濮城油田某一地区储层参数进行建模计算，建立相应的储层参数预测模型。在此预测模型的基础上，研究分析了储层孔隙度、渗透率、含油饱和度在平面上的分布规律。并从实际出发，依据储层的水驱规律，分析出剩余油的分布情况，找出剩余油的富集区主要分布在未被水淹的前远砂体及远砂砂体。通过挖潜措施的实施，提高了老油田的产量。

Using the method of random modeling with geologic data, the reservoir parameters for a certain area in Pucheng oil field are measured and calculated, and then the model is set up for predicting the reservoir parameters correspondingly. Based on the modeling results, the distribution laws are studied and analyzed for porosity and permeability of reservoir and oil-bearing saturation on the horizontal zone. The distributed conditions of residual oil are analyzed and known with the law of water-displacement-residual oil practically. It is found that the oil enriched zones are primary located in the unflooded far front sand body and frontier sand body. The production of maturing fields are increased by taking the measures of increment of potential resources.
