THEORETICAL MODEL ABOUT FRACTURE POROSITY, PERMEABILITY AND STRESS FIELD IN THE LOW-PERMEABILITY SANDSTONE

  • 摘要: 低渗透砂岩储集层普遍发育裂缝, 裂缝不仅是重要的流体渗流通道, 而且在油井周围的发育程度直接影响着油井的生产能力.目前裂缝定量化预测方面存在的焦点问题是:缺乏一个有效而合理的力学模型, 裂缝渗透性的求取方法仍处于半定量化, 不具通用性.以史深100块沙三中储集层为目标, 从应力场和裂缝主要参数的关系入手, 以裂缝开度为桥梁, 通过实验和理论推导的方法, 建立了构造应力场和裂缝孔隙度、渗透率之间的定量关系模型.在岩石力学参数测试结果和地质模型建立的基础上, 对目的层裂缝发育时期的古构造应力和现今地应力进行数值模拟, 将结果代入关系模型, 计算研究区裂缝孔隙度和渗透率的空间分布, 进而指导低渗透砂岩油藏的裂缝参数定量预测、产能规划及井网部署.
