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.
In order to study the geophysical properties of reservoir fluids and solve the modeling problem of reservoir fluid physics model, the method of making composite materials with epoxy resin and polymer water-absorbing materials is explored for the first time, and the reservoir fluid model materials are explored and developed.First, The formulation and production process of reservoir fluid materials, namely, preparation of matrix materials, preparation of storage and dispersion, vacuum mixing, pouring and solidification.Secondly, the microstructures, longitudinal wave velocity and spectral characteristics of reservoir fluids were tested and analyzed Finally, a three-dimensional physical model was made to investigate the application effect of reservoir fluid materials.It is concluded that the comprehensive characteristics of the reservoir fluid materials produced have good similarity with the reservoir fluid geology features, and can be controlled by controlling water and gas To produce reservoir fluid models with different fluid contents, different P-wave velocities and different dominant frequencies, which provides a new method for the quantitative study of reservoir fluids.
