The acoustic theory and borehole acoustic field distribution study and it's applied prospects

Acoustic is one main method for well logging, and it takes an important role for reservoir estimate. As the oil exploration aimed at anisotropy inhomogeneous porous reservoir presently, It is important to study the acoustic theory and borehole acoustic field distribution with numerical simulating so as to invent new logging methods and equipments to obtain enough information to evaluate the complex reservoir characters quantificationally and identify the hydrocarbon zone accurately. This paper gives an review about acoustic theory and numerical simulation study, and point out it's developing trend and applied prospects.
