摘　　要：凝析油气藏具有油轻气重特点,油气层识别难度大。进行了模拟地层条件下不同气油比流体物性参数测定及饱和流体岩石物理实验联测研究。实验结果表明,声速、体积压缩系数对气体最敏感,其次是含氢指数。高气油比轻质油密度与低气油比凝析气密度差异甚小。岩石的纵波速度、体积模量、纵横波速度比随充注流体气油比增大而减小,横波速度略增大。该实验成果可为凝析油气藏油气测井识别方法的建立提供实验依据。It is difficult to distinguish oil and gas layer in condensate reservoir with characteristics of light oil and condensate gas by conventional logging curves. An experiment was designed to analyze the physical properties of the different gas-oil ratio reservoir fluid and petrophysical parameters saturated various gas-oil ratio fluid. The experiment results show that the fluid wave velocity and bulk compressibility are very sensitive to gas, next is the hydrogen index. The fluid density difference between the high GOR light oil and low GOR condensate gas is minimum. With the increase of gas-oil ratio in fluid, the rocks compression wave velocity, compression-shear wave velocity ratio and bulk modulus decrease, and shear wave velocity slightly increase. The experiment result provides experiment foundation to distinguish light oil and condensate gas layer.
