相控建模技术在江苏油田庄2断块中的应用
|
摘要
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 fault-block Z2 in Jiangsu Oilfield developed at the end of 1995 is now at a middle water-cut period,and its reservoir heterogeneity is severe.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 the facies-controlled modeling technology and on the basis of study results on geology,logging 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.And the recovery ratio is enhanced by the comprehensive supervisory steps.The successful application in the fault-block Z2 shows that the facies-controlled modeling technology can satisfactorily characterize the properties of the reservoirs with quick-change sedimentary microfacies and severe heterogeneity,providing a dependable geological model for the later development adjustment of oil and gas fields.
