摘　　要：对云南ＣＸ盆地采集的地表露头岩样，在模拟地层环境的温度、压力（孔压和围压）条件下测量了岩石的纵横波速度和各种动弹参数（包括体积压缩模量、杨氏模量、剪切模量和泊松比等），根据测试结果研究了该地区岩石的动弹参数的变化规律，以及地层埋深、温度、压力等因素对动弹参数的影响。The dynamic elastic parameters are important in seismic prospecting. This paper presents the ultrasonic data of velocities of P wave and S wave of exposure rock samples collected from CX Basin in Yunnan, and their dynamic elastic parameters (which include bulk compressibility modulus, Youngs modulus, shearing modulus and Poissons ratio) meesured by experiment under the simulated formation temperature and pressure (pore pressure and confined pressure). From the experimental results, the authors studied the variations of dynamic elastic parameters and the factors influenced them, such as the buried depth of formation, temperature, pressure, porosity and saturated water etc.
