摘要
顺序指示模拟方法是以指示克里金为基础的一种随机模拟方法。在濮城油田东区沙二下储层非均质性研究中,采用该方法对沙二下亚段的渗透率进行了研究,并与普通克里金法建立的模型进行了对比。结果表明,普通克里金法具有平滑效应,不宜用来研究储层的非均质性。而顺序指示模拟方法更能反映参数的细节变化,并能够表征由于缺乏资料等原因而引起的不确定性。因此,该方法更适合储层非均质性的研究。
Sequential indicator simulation is a kind of stochastic modeling method based on indicator Kriging. This method is used to modeling the permeability distribution of a sand bed of the Shahejie formation(Eocene) in Pucheng oilfield, Henan province. The results are compared with ordinary Kriging, showing that the ordinary Kriging has a smoothing effect and is not suitable to describe reservoir heterogeneity, while the sequential indicator simulation is a better method to characterize reservoir heterogeneity It can produce many realizations The difference between these realizations reflects an uncertainty of the model because of lacking in data or other reasons
