页岩气跨尺度渗流模型及其应用研究

页岩气跨尺度渗流模型及其应用研究 2024-01-24

关键词:: 页岩气; 跨尺度; 数字岩心; REV; 分馏

进入21世纪以来，非常规油气获战略突破，页岩油气成为油气资源接替的重要新领域。页岩气藏储量大，分布广，具有非常大的开发潜能。然而，页岩中的多流动空间（有机/无机）、多流态（粘性/滑移/扩散）特征以及水力压裂使得气体运移成为复杂的多尺度系统。常规的流动模拟不再适用非常规的页岩气藏，建立一套适用于页岩气渗流的跨尺度模...

川东北须家河组致密砂岩断缝系统II：断层破碎带的结构特征

川东北须家河组致密砂岩断缝系统II：断层破碎带的结构特征 2024-01-24

关键词:: 四川盆地; 致密砂岩; 断缝系统; 断层破碎带; 地震属性

断层破碎带结构是逐渐而非某次剧烈变化形成的，这也直接导致了破碎带结构几何空间特征的复杂性。通常断层破碎带主要由断层核和破碎带这两个部分组成，但大规模或者构造变形强烈的断层中，断层破碎带可能会由单一断层核演化为具有多个核部的复杂结构。如何获得这样的结构特征，对研究断层破碎带控制下的油气运移规律有重要意义。基...
