摘　　要：二连盆地阿南油田阿11断块处于高含水开发阶段,储集层非均质性严重影响开发效果。为了精确描述储集层物性及其展布特征,综合应用地震、测井、地质和开发动态研究成果,应用相控建模技术,采用两种或多种建模方法联合工作的思路,分步建立了构造模型、沉积微相模型以及微相控制下的储集层属性模型。通过油气储集层相控与非相控物性参数模拟结果的对比,认为相控属性模型对油藏非均质性的描述更为合理,使Petrel地质建模与Eclipse数值模拟一体化无缝链接,依据模拟结果采取综合治理措施,提高了油藏采收率。阿南油田的成功应用表明,相控建模技术可较好地解决沉积微相变化快、非均质性严重的储集层物性参数的模拟,为油藏后期开发调整提供了可靠的地质模型基础。The fault-block All in the A＇nan Oilfield of the Erlian basin is now at a high water-cut period, and its reservoir heterogeneity has severely affected development results. In order to accurately describe the reservoir and its through-going characteristics, this paper establishes the structural model, the sedimentary microfacies model and the microfacies- controlled property model step by step using facies-controlled modeling technology with multiple stochastic modeling methods and on the basis of study results on seism, logging, geology and development performance. The comparison between facies-controlled modeling and non-facies-controlled modeling reveals that the facies-controlled property model is more reliable in describing reservoir heterogeneity. The successful application in the A＇nan Oilfield shows that the facies- controlled modeling technology can satisfactorily characterize the properties of the reservoirs with quick-change sedimentary microfacies and severe heterogeneity, providing dependable geological model for the later development adjustment of oil and gas fields.
