二层地质模型波场模拟,用有限差分进行波场的模拟,充分利用多波多分量地震记录，以及各向异性方面的独特信息，可有效地减少 纵波勘探的多解性，定量地描述裂缝储层，改善某些纵波资料成像不好地区的构造 成像。这样可获得比纵波分辨率高的多波剖面，从而有利于研究小幅度构造、断层、 裂缝裂隙等复杂地质现象，对油气勘探与开发具有现实意义和实用价值(Two-layer geological model wave field simulation, using finite difference wave field simulation to make full use of multi-wave multi-component seismic records, and the anisotropy of the unique information can be effective in reducing the P-wave exploration, multi-solution and quantitatively describe the crack reservoir to improve the poor image of some P-wave data area structure imaging. This availability of higher resolution than the longitudinal wave of multi-wave profile, thus contributing to the small amplitude structures, faults, cracks, fissures and other complex geological phenomena, for oil and gas exploration and development of practical significance and practical value)
