摘要:
江苏油田已整体进入高含水开发阶段,为满足油藏水动力调整需要,研究提出了油藏初始流场的概念,砂岩油藏初始流场定义为油藏在开发初期未经注水等后期改造状态下的潜在流体渗流能力。油藏初始流场研究可对油藏开发后期形成的优势流场与初始流场进行对比,为深入研究剩余油富集规律提供依据。影响油藏初始流场的因素众多,且各因素之间相互影响,采用模糊综合评判法开展定量综合评价,并利用层次分析法评判指标权重。针对江苏油田具体工区,采用重要性、独立性、实用性、全面性等评价指标筛选原则,选择储层非均质性、渗透率、沉积相、裂缝、黏土含量、原油黏度和地层倾角为评价指标,通过指标权重的计算和初始流场强度指数(I)计算,获得了G6断块初始流场强度场。
Abstract:
Jiangsu Oilfield has entered the stage of high water-cut development stage as a whole.In order to meet the needs of reservoir hydrodynamic adjustment,the concept of the initial flow field of the reservoir is proposed in this study.The initial flow field of the sandstone reservoir is defined as the potential fluid seepage capacity of the reservoir without water injection in the early stage of development and other post-modification.The study of the initial flow field of the reservoir can compare the dominant flow field formed in the later stage of reservoir development with the initial flow field in the early stage of the reservoir,and provide a basis for in-depth study of the remaining oil enrichment law. Since there are many factors affecting the initial flow field of the reservoir,and the factors affect each other,the fuzzy comprehensive evaluation method is used to carry out quantitative comprehensive evaluation,and the analytic hierarchy process is used to evaluate the index weight. According to the study on the specific work area of Jiangsu Oilfield,the evaluation index screening principles such as importance,independence,practicability,and comprehensiveness are adopted to select reservoir heterogeneity,permeability,sedimentary facies,fracture,clay content,crude oil viscosity,and formation dip angle as evaluation indexes.Through the calculation of index weights and initial flow field intensity index(I),the initial flow field intensity field of G6 Fault Block has been obtained.
