【摘要】 本文以二连盆地阿南油田阿11复杂断块油藏为例,剖析了水下扇体相控储层物性参数建模方法及应用。该断块目前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,并实现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基础。同时,针对环渤海湾地区复杂断块油藏各类沉积环境对相控建模的适用性做了总结,提出了推广应用完善建议。更多还原

【Abstract】 This paper analyses underwater fan body facies-controlled reservoir petrophysical parameters modeling method, and application for the complex fault-block reservoirs All in A’Nan Oilfield, Erlian Basin. The fault-block All in A’Nan Oilfield is now at a high water-cut stage, and its reservoir heterogeneity has severely affected development results.In order to accurately describe the reservoir and its characteristics, this paper establishes a structural model, a sedimentary microfacies model and a microfacies-controlled petrophysical model, step by step. Using a facies-controlled modeling technology with multiple stochastic modeling methods, and on the basis of results on seismic, logging, geology and development performance. The correlation of analogy results between facies-controlled petrophysical parameters and direct petrophysical parameters reveals that the facies-controlled attribute model is more reliable in describing reservoir heterogeneity. It consists of integrated Petrel geological modeling and Eclipse numerical simulating, so synthetical methods have been adopt, this enhancing oil and gas recovery efficiency. It shows that the facies-controlled modeling technology can satisfactorily show the petrophysical parameters of reservoirs with variable sedimentary microfacies and severe heterogeneity, this providing a dependable geological basis for the later development adjustment of oil and gas fields. At the same time, applicability of facies-controlled modeling to all kinds of sediment environment is summarized in complex fault-block reservoirs, and recommended for similar application around Bohai Bay.更多还原
