摘　　要：研制了一种用于石油三次开采过程物理模拟的仪器。根据驱替机理和相似原理模拟地层地质的温度和压力条件,借助于计算机、传感器等技术,研究模拟驱油体系在多孔介质中的渗流特性、电阻率变化及驱油效率。利用LabWindows/Cvi编写上位机测控程序,使用串口与智能仪表通信,获取温度压力值并做相应的显示和处理,通过编程PCI数据采集卡控制外部硬件。An instrument for the third oil exploration was designed, for the simulation of the geological formation temperature and pressure conditions, by similar principles and flooding mechanism. Computers, sensors and other technologies were used to study the flow characteristics, resistivity change and oil displacement efficiency of the simulated flooding system in porous media. By using LabWindows/Cvi to design PC monitoring program, using serial communication with the smart meter, the temperature and pressure values were obtained and processed. The external hardware was controlled by use of PCI data acquisition card.
