摘要: 总结了储层建模研究的几个基本观点,提出了采用确定性微相建模与随机参数模拟相结合以提高整体建模精度的思路.在微相确定性建模的基础上,采用相控蒙特卡洛模拟预测储层参数分布,生成了参数分布.对低弯度分流河道砂体建模实例的研究结果表明,相控条件下的参数随机模拟精细刻画了储层的非均质性.对于资料信息点足够大的处于成熟开发的油田,采用研究区实际统计分布函数得到的随机模拟结果更接近于地下实际的非均质构型,为油田不确定性评价提供了必要的手段.

Abstract: Some basic points of view about reservoir modeling for mature development of oilfield were summarized.A reserch thought for integrating both deterministic and stochastic methods for improving the accuracy of modeling was put forward.On the basis of micro-facies deterministic modeling,the parameter distribution predicted by Monte-Carlo facies-controlled simulation were realized.An exemplification shows that stochastic simulated parameters can characterize heterogeneity of reservoir in detail.For the mature developed oilfield with enough information,the real statistic data from the specific studied area can be applied to the stochastic simulation.The result is much close to the heterogeneity pattern of subsurface.The facies-controlled modeling can provide a necessary approach to uncertainty evaluation of oilfield.

Key words: oilfield development, reservoir modeling, geological constraining, facies-controlled modeling, stochastic parameter, Monte-Carlo simulation, heterogeneous reservoir
