Abstract
The embodiment of the disclosure relates to an elastic wave stress tensor double-dot product seismic imaging method and device. The method comprises: obtaining a decoupled particle vibration velocity vector wavefield by utilizing the existing decoupled wave equation method for the receiver wavefield; then obtaining a decoupled pseudo-stress wavefield by constructing the decoupled pseudo-stress equation by using the obtained decoupled particle vibration velocity vector wavefield; and finally computing a source second-order stress tensor wavefield and the decoupled receiver second-order stress tensor wavefield by using the double-dot product cross-correlation imaging condition algorithm, to obtain the final scalar imaging results. With the embodiment of the present disclosure, the combined P-wave and S-wave stress exploration can be realized, therefore, the obtained imaging results can be used to accurately predict the risk of gas exploration.
