飽和水與干燥碳酸鹽巖聲波各向異性研究
[Abstract]:In order to understand the acoustic wave propagation law of carbonate rock in saturated water and dry condition, the acoustic wave of carbonate rock is analyzed by acoustic physical experiment and spectrum numerical analysis of square carbonate rock sample after drying and saturated water, respectively. The propagation velocity and spectral characteristics are studied. The results show that the wave shape is loose, the period increases obviously, and the period increases further after saturated water, but the position of maximum amplitude is advanced. The wave velocity and main frequency of rock samples have obvious anisotropic characteristics. The more developed the fracture, the greater the anisotropy coefficient of wave velocity and main frequency, and the lower the longitudinal wave velocity and main frequency are in the vertical fracture direction. Both the wave velocity and the anisotropy coefficient of the main frequency of the dry core can be used to evaluate the anisotropic characteristics of the core. The main frequency is more sensitive to the anisotropic characteristic of the core, and the anisotropy coefficient of the core decreases greatly after saturated water. This study provides a basis for the correct use of acoustic logging data and the recognition of anisotropic characteristics of carbonate reservoirs.
