【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。图8参18更多还原

【Abstract】 The fault-block A11 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 faciescontrolled 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.更多还原
