The elastic vector reverse time migration imaging method solves the scalar imaging problem of the longitudinal and transverse wave fields, and the imaging precision of elastic reverse time migration under a complex construction is improved.

Image Processing Method Eureka Patsnap On this basis, this paper proposes the pp wave and ps wave adcig extraction method based on the elastic reverse time migration (ertm). considering the low wavenumber noise in pp wave adcigs, an angle attenuation superposition strategy for adcigs is proposed to improve the migration imaging accuracy. By directly inputting the seismic multi component data and building the underground elastic vector seismic wave field by combining with multi component, the method can be used for accurately imaging for complex earth medium. We present a fast and accurate ertm method using the developed lssfdm based on decoupled elastic wave equations. the extrapolation and decomposition of different mode waves are very important to efficiently obtain multi wave depth images for elastic reverse time migration (ertm). Elastic reverse time migration (ertm) has emerged as a critical seismic imaging technique that exploits the full vector nature of elastic waves to generate high fidelity subsurface.

Elastic reverse time migration (ertm) has emerged as a critical seismic imaging technique that exploits the full vector nature of elastic waves to generate high fidelity subsurface. Prestack elastic reverse time migration (rtm) of multicomponent seismic data requires separating pp and ps reflections before, or as part of, applying the image condition, and using image. We evaluated three kinds of imaging conditions in elastic rtm. the first kind of imaging condition involves the crosscorrelation between the cartesian components of the particle velocity. However, the migration image of deep structures is always blurred due to the shielding effect of overburden rock on seismic waves. to overcome this issue, we develop an elastic reverse time migration approach for insufficient illumination. In this paper, we use elastic modeling process to generate p&s shot records. then we use acoustic rtm and least squares rtm to migrate these elastic data, using p and s velocities in different experiments.
