摘要: 利用储层随机建模的指示模型,以大庆油田一个地区的222口井测井资料求取的岩相单元资料为依据,用多个随机种子分布求取的储层随机建模的多个实现,对该地区岩相单元空间分布进行了预测.从检验储层随机建模砂体预测的精度的角度,对砂体预测符合率进行了定义,并研究了随机建模砂体预测符合率和随机建模岩相单元比例的预测值.利用这两个概念,可以从储层随机建模的岩相单元空间分布的多个实现中选择出最合理的岩相单元.该方法具有较高的砂体预测符合率,尤其适用于大庆油田这样已有多套井网加密的地区.

Abstract: The multi-stochastical realizations of reservoir stochastical modeling with indicator model were used to predict the spatial distribution of lithological units with data gotten from 222 wells in a mature area of Daqing Oilfield.In the view of the inspection of prediction precision,the conformation rate of sandbody prediction was defined with stochastical modeling,and the prediction value of lithology unit proportion was studied.The multiple realizations of spatial distributions of lithological units were optimized with the two standards.The conformation rate of this approach is obviously higher than that of usual method.This method is available specially to mature oil fields with dense well nets such as Daqing Oilfield.

Key words: reservoir, lithology facies, multi-stochastical modeling, sand body, prediction, conformation rate
