低渗透储层的吸水特征及影响因素分析的中期报告
摘要：
低渗透储层的水文地质条件极其复杂，需要系统地分析吸水特征及其影响因素，以揭示其水文地质机制，为储层的开发和管理提供科学依据。本中期报告主要针对低渗透储层的吸水特征及影响因素展开研究，采用文献综述、实验室测试和数值模拟等方法，对低渗透储层的吸水特征及其影响因素进行深入分析，并结合实际案例进行验证。研究结果表明：低渗透储层的吸水特征具有非线性和时变性，与储层的渗透率、孔隙度、亲水性等多个因素密切相关。其中，渗透率、孔隙度和亲水性是影响储层吸水特征的三个主要因素。此外，研究还发现，储层中岩石颗粒和杂质的存在会对吸水特征产生一定的影响，应引起重视。这些研究成果对于深入掌握低渗透储层的水文地质特征，指导储层的开发和管理具有重要意义。
