基于分形理论的非常规油气渗流规律研究

基于分形理论的非常规油气渗流规律研究 2024-01-24

关键词:: 混合分形; 非常规油气; 页岩; 致密砂岩; 渗透率

非常规储层具有非均质性强、渗透率超低，且油气运移规律复杂的特性，与常规储层有很大不同。探寻非常规储层中影响油气运移的关键因素，准确高效地评价渗流趋势，是国内外学者和工程师们的关注焦点。本文以分形理论为基础，以页岩和致密砂岩为对象，构建了单相流体和两相流体在页岩和致密砂岩中的渗流模型，为研究非常规储层的油气渗流规律...

致密砂岩微裂缝网生长机制的研究

致密砂岩微裂缝网生长机制的研究 2024-01-24

关键词:: 致密砂岩; 水力压裂; 微裂缝网; 离散元法; 岩石微结构

非常规油气在全球能源中扮演的角色越来越重要。致密砂岩储层作为非常规储层的典型代表，对其实现大规模经济开采一直是能源行业关注的焦点。但致密砂岩通常具有低孔隙度和低渗透率的特点，所以需要在储层中构建人工缝网来增加油气从孔隙向井筒运移的能力。因此研究致密砂岩微裂缝网形成的力学机制至关重要。本文聚焦于以脆性矿物为主的致密...
