一、数学处理及计算方法§1 射线轨迹计算简述我们知道,在石油地震勘探中,几何地震学迄今仍不失为资科处理与剖面解释的简要理论根据。针对各种复杂地层构造的模型,或者针对预先知道的具体模型,进行射线轨迹的计算,确定自激自收的时距曲线,将有助于时间剖面的解释。为此,我们探讨了射线轨迹计算中的数学现象,复杂地层构造的教学表示方法及计算步骤的一体化问题,研制了适应于任何复杂地层构造射线轨迹计算的通用程序,并且已经设计与计算了一批模型。这里,先简要地叙述上述计算的数学内容。问题的提法是:巳知任意形状的一个复杂地层构造如图1所示。如果在地面上任一
First, the mathematical treatment and calculation § 1 ray trajectory calculation briefing We know that in the oil seismic exploration, geometric seismology is still a brief theoretical basis for the processing of resources and profile interpretation. Aiming at the models of all kinds of complex stratigraphic structures or calculating the trajectory of the trajectory according to the specific model known in advance, it is helpful to explain the time profile. For this reason, we have discussed the mathematical phenomena in ray trace calculation, the teaching method of complex formation formation and the integration of calculation steps, and developed a general procedure adapted to the ray trace calculation of any complex formation, and have designed and calculated A batch of models. Here, the mathematical contents of the above calculation are briefly described. The problem is that a complex formation known to have any shape is shown in Figure 1. If on the ground either
