江苏油田庄2断块于1995年底投入开发,目前已进入中含水期,储层非均质性严重。为了精确描述储层物性及其展布特征,综合应用地质、测井和开发动态等研究成果,应用相控建模技术,分三步建立了构造模型、沉积微相模型和沉积微相控制下的储层属性模型。通过相控与非相控模拟结果的对比,认为相控模型对油藏非均质性的描述更为合理,依据模拟结果采取综合挖潜措施,提高了油藏采收率。在江苏油田庄2断块的成功应用表明,相控建模技术可较好地解决沉积微相变化快、非均质性较严重的储层物性参数的模拟,为油藏后期开发调整提供可靠的地质模型基础。
The Zhuang 2 fault block of Jiangsu Oilfield was put into development at the end of 1995 and has now entered the middle water-cut period with serious reservoir heterogeneity. In order to accurately describe the reservoir physical properties and its distribution characteristics, comprehensive application of geological, logging and development dynamics and other research results, the use of phase control modeling technology, in three steps to establish the structural model, sedimentary microfacies model and sedimentary microfacies Reservoir property model. According to the comparison between the phased and non-phased simulation results, it is considered that the phased model is more reasonable to describe the reservoir heterogeneity. According to the simulation results, the comprehensive potential tapping measures are taken to improve the oil recovery. The successful application of Zhuang 2 fault block in Jiangsu Oilfield shows that the phased-control modeling technique can better simulate reservoir physical parameters with rapid changes in sedimentary microfacies and more serious heterogeneity, and provide reliable information for later reservoir development and adjustment The basis of the geological model.
