摘　　要：油气储层的物性参数是油气地球物理（特别是勘探地球物理）的重要基础资料。油气储层深埋地下，只有在地层条件下测试获得的物性参数才能代表油气储层的真实性质。不同物性参数之间有一定的内在联系，只有在相同地层条件下，同时测试这些物性参数才能准确地研究它们之间的内在关系。“岩石物性参数自动测试系统”就是国际上第一台能够在地层条件下（温度：常温～２００°Ｃ；围压：１～１４０ＭＰａ；孔隙压力：０～７０ＭＰａ；轴压：０～１０００ｋＮ）同时动态地测试油气储层的岩石力学参数（静态杨氏模量、泊松比、抗压强度等），储层物性参数（孔隙度、渗透率）和声波速度（Ｐ波和Ｓ１，Ｓ２波，并由此得出动态弹性参数、杨氏模量、泊松比、拉梅常数、体积模量、剪切模量）等的大型仪器设备。该设备由岩石力学测试系统、超声波测试系统和孔隙体积变化及渗透率测试系统组成。The physical parameters of oil and gas reservoir rocks are important fundamental data for petroleum geophysics, especially for exploration geophysics. Oil and gas reservoirs are under the surface at a large depth. The reservoir physical parameters, which are measured only under formation conditions, can represent the real properties of reservoir rocks. There is also a certain internal relation between various physical parameters. The relation can be accurately studied only by use of the parameters measured simultaneously under the same formation conditions. “Rock physical parameter automatic testing system” is the first system in the world to measure simultaneously rock mechanics parameters (static Young′s modulus, Poisson′s ratio and compressive strength), reservoir petrophysics parameters (porosity and permeability), and ultrasonic velosities ( v P, v S 1 , v S 2 , also the dynamic elastic parameters) under different formation conditions (temperature: ambient～200°C, confining pressure: 0～140 MPa, pore pressure: 0～70 MPa, axial load: 0～1000 kN). This large scale instrument consists of rock mechanics testing system, ultrasonic velosity testing subsystem and pore volume change and permeability testing subsystem.
