Abstract

Реализуемый компьютером способ псевдоакустического распространения квази-Р волн, которое остается устойчивым в анизотропной среде с переменным наклоном и не ограничено слабыми анизотропными условиями. Способ включает в себя сбор объема сейсмической разведки для интересующей подповерхностной области и определение геометрии моделирования для зоны сейсмической разведки. Способ дополнительно включает в себя передачу по меньшей мере одного волнового поля через объем сейсмической разведки, используя геометрию моделирования для исходных условий и предотвращая накопление энергии вдоль оси симметрии апизотронных областей в объеме сейсмической разведки, и обеспечивая положительные коэффициенты жесткости в соотношениях напряжения-деформации используя конечные скорости квази-S волн, тем самым, получая устойчивое волновое поле. Способ включает в себя использование устойчивого волнового поля для формирования подповерхностных изображений интересующей подповерхностной области.The computer-implemented method of pseudo-acoustic propagation of quasi-P waves, which remains stable in an anisotropic medium with a variable inclination and is not limited to weak anisotropic conditions. The method includes collecting a seismic survey volume for the subsurface region of interest and determining the modeling geometry for the seismic survey zone. The method further includes transmitting at least one wave field through the seismic exploration volume, using the geometry of the simulation for the initial conditions and preventing energy accumulation along the symmetry axis of the apisotronic regions in the seismic exploration volume, and providing positive stiffness coefficients in the stress-strain relations using the finite velocities quasi-S waves, thereby obtaining a stable wave field. The method includes the use of a stable wave field for the formation of subsurface images of the subsurface region of interest.
