So called reservoir is physical or mathematical; for a physical system, the mathematical model is a system of partial differential equations with related initial and boundary value conditions, it can describe important physical process occurring in the system, for example, the process occurring in reservoir, which mainly concludes flow of fluids and transportation of mass, gravity、 viscosity、compressibility have effect to it; differential equations describing this process are obtained by combining Darcy law of every phase and its mass equilibrium in differential form.

这种模型是物理的或数学的；一个物理系统的数学模型，是偏微分方程组和适当的一组初、边值条件的总体，它能够描述在系统中发生的重要的物理过程，比如在油藏中发生的过程，主要是流体的流动和质量的转移，重力、粘滞力、压缩性等在流体流动过程中都是起作用的；描述这个过程的微分方程是由将各相达西定律和各该相的微分形式的物质守恒相结合而得到的。

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

本研究通过自行设计制造的催化剂模压成型过程分析仪（Catalyst Molding Process Analyzer， CMPA）和催化剂力学性质测试仪（Catalyst Mechanical Properties Tester， CMPT），以Fe-Cr系高温变换催化剂片剂为研究对象，对成型过程和受压破碎过程提供了全过程动态研究的新手段；本研究利用正交实验设计方法考察了固体催化剂成型过程中诸因素（包含预密致比例、煅烧时间、煅烧温度和石墨含量等）对催化剂成型体强度的影响，并对成型条件进行了优化；根据实验结果，关联确定了固体催化剂成型过程中的密度－压力关系式，并对方程中诸因子的物理意义进行了描述；提出了一种利用宏观弹性模量来表征成型催化剂的力学性质的方法；研究讨论了成型压力对催化剂成型体强度性质的影响，结果表明：对于催化剂成型体的强度和比表面性质，成型压力存在着一个最佳值，过高的成型压力会导致比表面积和侧压强度的降低；不适当的成型压力的维持时间会破坏&压力回弹&作用，造成催化剂成型体的机械强度明显降低。
