摘　　要：为了研究储层流体的地球物理特性,解决储层流体物理模型建模难题.本文首次采用环氧树脂材料和高分子吸水材料制作复合材料的方法,探索开发了储层流体模型材料.首先,介绍了储层流体材料的配方和制作工艺,即配制基体材料,配制储集分散液,真空混合,浇注固化.其次,对储层流体材料的微观结构、纵波速度、频谱特性等特征进行了测试分析.最后,制作了三维物理模型,考察了储层流体材料的应用效果.研究认为,制作的储层流体材料的综合特性与储层流体地质体特征有很好的相似性,可以通过控制水和气的含量来制作不同流体含量、不同纵波速度和不同主频的储层流体模型,为储层流体的定量化研究提供一种新方法.To study the geophysical properties of reservoir fluids, and solve the problem of reservoir fluid physics modeling. Reservoir fluid materials were developed by epoxy resin material and super absorbent polymer , this method was the first used for the production of composite materials. Firstly, the formulation and production process of reservior fluid materials were introduced. Preparing a base material and reservoir disperation, then vacuum mixing, and pouring cured. Secondly, the microstrueture structure, P-wave velocity, spectral characteristics of reservior fluid material were tested. Finally, the application effect of reservior fluid materials were investigated by 3 D physical model. The research results show that production of reservior fluid materials are similar with reservior fluid geological characteristics. Different fluid content, different Pwave velocity and different frequency of the reservoir fluid model were producted by controlling the content of water and air. It provides a new method for the quantitative analysis of reservoir fluid.
