本文应用波动方程的克希霍夫积分定理,建立了一种单层界面三维理论合成记录的近似计算公式.为讨论问题方便起见,假设地层模型沿坐标轴Y方向没有起伏,但沿X、Z方向可以任意分布.当测线与构造的走向成任意方位角时,二维问题就变成了三维问题.本文较详细地讨论了理论共炮点合成记录和理论自激自收合成记录的一种数值解法,解法力求简单,以适应中小型电子计算机算题.最后,本文探讨了在三维空间中克希霍夫“广义倾斜因子”存在的可能性.
In this paper, the Kirchhoff’s integral theorem of wave equation is used to establish an approximation formula of three-dimensional theoretical synthetic record of single-layer interface. For convenience of discussion, assuming that there is no undulation in the Y-axis direction of the formation model, Direction can be arbitrarily distributed.When the line and the structure of the direction into any azimuth, the two-dimensional problem becomes a three-dimensional problem.In this paper, a more detailed discussion of the theoretical total shot synthesis and self-sustaining synthetic record of a The numerical solution and the solution are simple and can be adapted to small and medium-sized electronic computer programs.Finally, this paper explores the possibility of the existence of “Kirchhoff” generalized tilt factor in three-dimensional space.
