The velocity difference between the two layers of the lower crust is not obvious 下地殼的兩構(gòu)造層速度差異不明顯。
Average weathering velocity 平均風(fēng)化層速度
New method of using seismic velocity to predict layer drillability and drilling rate 利用地震層速度預(yù)測地層可鉆性和鉆速的新方法
According to the theory of generalized inversion , we can get the parameters of velocity and thickness in each layer with joint inversion of multilayer reflection wave ' s travel time 摘要從廣義反演理論出發(fā),對多層反射波的走時(shí)聯(lián)合反演,可以同時(shí)獲得所有的各層速度及厚度參數(shù)。
