摘　　要：介绍了地层测试器发展现状及流体仿真软件HyPneu的功能,分析了地层测试器EFDT推靠坐封液压系统原理,运用HyPneu软件建立了推靠坐封液压系统的仿真原理图。从液压元件的选择角度,对推靠液压系统的推靠坐封装置伸出和收回进行了仿真,监测了推靠坐封装置伸出和收回的压力、时间参数。用仿真软件对推靠坐封液压系统系统进行了优化设计,仿真结果与实验数据吻合,验证了液压系统设计的合理性。This paper presents the development of the formation tester and the function of the fluid simulation software HyPneu. The principle of the pushing ＆ setting hydraulic system of the formation tester EFDT is analyzed. The schematic diagram of the hydraulic system is established with HyPneu. The withdrawing and expanding processes of pushing ＆ Setting device are simulated. The pressure and time parameters of withdrawing and expanding process are detected. The hydraulic system is optimized with HyPneu. The simulation results agree well with the experimental data.
