Hou Chunhui, Wu Xiangyun, Wang Ke Association. Inversion of Reservoir Permeability with Stoneley Wave Attenuation. Logging Technology, 1997,21 (3): 162 ~ 166 The cylindrical sound source in a fluid well is surrounded by a porous medium saturated with the same fluid. Based on the theory of acoustic field excited by the sound source, the method of partial wave analysis is used to study the Stoneley wave corresponding to the number of poles in the complex wave number plane. A linear least squares inversion model for reservoir permeability inversion using Stoneley amplitude attenuation is established. Using the synthetic full-wave data under different reservoir conditions, the stability, convergence and error of the inversion results are carefully investigated. The inversion results show that this is a simple and effective method of calculating permeability of formation.
