CMS-200/300自动岩芯测量系统分析

CMS－200／300是代表世界先进水平的岩芯物性分析仪器，文章综合分析了它的测试原理，测试方法，系统流程，系统结构，软件功能及测定多数的应用。其测试原理是在非稳态流理论的基础上，根据Forchheimer方程推导出渗透率计算式；测试方法是让一已知体积的气罐充满氦气到一初始压力，然后通过岩芯放出，根据测出的罐内压力变化率即可计算出岩芯的渗透率、滑脱因子及惯性系数；在系统流程的基础上建立的系统结构包括液压岩芯夹持器总成、岩芯自动装卸系统、标准体积罐及其管路和传感器、计算机和打印机；应用软件为菜单式结构，模块独立性强，具有系统初始化，参数测量，数据管理及系统诊断等功能；指出了测定参数的应用。

The Analyzing on CMS-200/300 Auto Core Measurement System

CMS-200/300 is the most advanced core physical characteristics analyzing instrument in the world. This paper discussed the principle and the way of measuring, the instrument operation diagram, the configuration, the software function and the application of its measuring pararneter. The basement of measuring principle is the Forchheimer equation in the none-stable flow theory and by it the permeability computation.
