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)

最小二乘法拟合进行n次多项式拟合,N用来控制拟合的次数,例如N=5时进行4次多项式拟合,还回的是拟合系数(Least squares fit polynomial n times, N is used to fit the number of control, e.g., N = 5 When quartic polynomial fitting, further back are fitting coefficients)
