地震射线追踪法的模型研究与应用
|
摘要
论述了用数字方法设计出地层弹性波速度模型的原理和方法,阐述了地震射线追踪法的算法并用其对数字模型的反射、折射波时距曲线做了计算,通过实例分析了复杂速度结构与地震剖面的对应关系,可指导解释人员根据实际地质情况任意设计地层模型进行计算,很快得出结果。
This paper deals with the principle and method of the utilization of the digital technique to design the velocity model of stratigraphic elastic wave,recounts the algorithm of seismic ray tracing method and makes calculation by using its reflection and refraction wave time-distance curves to the digital model.With practical examples,the paper analyzed the correlation between the complex velocity structure and the seismic profile.The achievements made can guide the interpreter to design a stratigraphic model according to practical geological conditions and make calculation,and the result can be obtained very fast.
