Web1. mar 2010 · These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0 (also read LAS-format 3.0), and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls. Definition of reflection coefficient 1. The ratio of the amplitude of the displacement of a reflected wave to that of the incident wave; reflectivity. The relationship is obtained by solving boundary condition equations which express the continuity of displacement and stress at the boundary. Zobraziť viac Assume the incident, transmitted and reflected pulses have the following forms, and note with reference to Dix’s original figure that the incident and transmitted pulses travel to the right and the reflected pulse travels to the … Zobraziť viac Equation (2) implies that ( ∂ u ∂ t ) 1 = ( ∂ u ∂ t ) 2 {\displaystyle ({\frac {\partial u}{\partial t}})_{1}=({\frac {\partial u}{\partial t}})_{2}} … Zobraziť viac Equations (14) and (15) are simultaneous in a and b and so can be solved for b, which is the reflection coefficient for normal incidence.
