鄂尔多斯盆地上三叠统延长组致密砂岩储层绿泥石对润湿性的影响

鄂尔多斯盆地上三叠统延长组致密砂岩储层绿泥石对润湿性的影响 2024-01-24

关键词:: 润湿性; 绿泥石; 孔隙尺度; 岩芯尺度; 延长组; 鄂尔多斯盆地

润湿性是储层的重要性质,对提高采收率和油气运移研究至关重要.岩石矿物组成影响储层的润湿性,但对其具体作用仍没有明确认识.文章以鄂尔多斯盆地延长组储层为例,开展了储层岩石学特征和润湿性特征的综合研究,分析了绿泥石对砂岩储层润湿性的影响作用.结果表明,延长组储层内绿泥石非常发育,主要包括碎屑状绿泥石、绿泥石膜和黑云母...

克拉美丽断裂带构造变形特征及其成因演化

克拉美丽断裂带构造变形特征及其成因演化 2024-01-24

关键词:: 构造变形; 分形维数; 成因演化; 克拉美丽断裂带; 准噶尔盆地东北缘

克拉美丽断裂带作为中亚造山带的一级盆缘断裂带,控制着准噶尔盆地东北缘的形成和演化,是解析盆-山耦合的关键要素。该断裂带因经历了多期次构造运动的叠加,构造变形错综复杂。目前对克拉美丽断裂带的形成与演化存在许多认识上的分歧,对演化过程中不同构造阶段的构造变形特征还缺少系统的研究。文中通过野外露头踏勘、实测及剖面演化分...

深层-超深层碳酸盐岩多类型储集体地震预测

深层-超深层碳酸盐岩多类型储集体地震预测 2024-01-24

关键词:: 深层-超深层; 碳酸盐岩储层分类; 相控型储层; 面控型储层; 断控型储层; 地质指导地震预测技术; 川西雷口坡组潮坪相气藏; 顺北奥陶系断控油气藏; 大牛地奥陶系不整合面气藏

塔里木盆地、四川盆地以及鄂尔多斯盆地深层-超深层碳酸盐岩油气藏是中国油气勘探的重要领域.由于中国海相深层碳酸盐岩储层发育的主控因素差异很大，碳酸盐岩储集体类型多，非均质性极强.随着深度增加，海相地层地震资料信噪比低、分辨率变差，增加了碳酸盐岩储层地震预测的难度.本文提出了以“相、面、断”三种端元为基础的深层碳酸盐...
