Експериментальні дослідження акустичних та електромагнітних хвиль у навколосвердловинному просторі при локальному імпульсному та гармонічному навантаженні в буровій колоні Head Ulitko Аndriy Feofanovich, Registration Date 23-02-2004 Organization Taras Shevchenko Kiev university popup.description2 A model of the splitting of complete spatial motion of elastic solid with piezoeffect into translational and relative motions has been suggested. Vector generalized dynamic Lame equation of motion have been found and accom-panied with conjugate Euler equation and the equation for electrostatic potential function. For the media with finite con-ductivity some conditions of electromagnetic wave dec-reasing have been found for propagation in the formations surrounding the borehole. For the electromagnetic channel of RCS several statements of boundary value problems for potential functions are suggested and their solutions have been built up for opened borehole and surrounding media. Asymptotic sulution of boundary value problem for spherical source radiating in the steadily rotating medium has been built up.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
