在古生界、中生界和新生界地层发育比较齐全的塔里木盆地内,地震波传播的真速度 V(z)函数多呈非线性的形式,即在 V(z)=V_0(1+βz)~(1/N)中,N≠1。据此,本文讨论了以下问题:(1)判别速度传播规律的方法;(2)求取参数 V_0、β的方法;(3)变速曲射线空校法与变速直射线空校法;(4)利用叠偏剖面成图的方法及有关量板的计算方法。文中各点均以塔里木盆地为实例验证有关方法的效果。 In the Tarim Basin where the Paleozoic, Mesozoic and Cenozoic strata are well-developed, the true velocity V (z) of seismic waves propagates mostly in a non-linear form, that is, V (z) = V_0 (1 + βz) ~ (1 / N), N ≠ 1. Accordingly, this paper discusses the following issues: (1) the method of determining the velocity propagation law; (2) the method of obtaining the parameters V_0, β; (3) Method of using stratified profiling to map and calculation method of related measuring plate. In this paper, all the points in the Tarim Basin as an example to verify the effect of the method.
