Acoustic logging for Directional Wells in order to detect the Mechanical Anisotropy.

摘要

A method of digrafu00eda Acoustics for an oil or gas Well,Comprising: transmitting Acoustic signals at different azimutes in an oil or gas Well; and receive in response to Acoustic signals transmitted Signal azimuth, respectiveFrom the well to determine the anisotropy of Mechanical Structure Land crossed by a well,Where the received signals have azimuthal Wave forms that respond to the understanding,The Shear and Stonely Waves produced in the Earth's structure in response to Acoustic signals transmitted.This method can be used in conjunction with a previous technique in which a sample is removed from the Borehole Core and analyzed outside the well.
