Complexity Of Static Correction

The geometric seismology theory supposition is works as the observation surface is a horizontal plane, the underground medium for the even stratified medium, the earthquake wave which excitated by the identical shot-point, when arrives the ground after some stratum reflection, its distance curve is a hyperbolic curve. Land seismic exploration, but too often the case: The surface layer condition very is often complex, the observation surface usually is the fluctuation uneven, but the surface layer depression speed belt speed and thickness also are the lateral changes, like this can cause the earthquake wave propagation time different delays. Therefore, the actual observation obtains the reflection time, is not the standard hyperbolic curve, but was a distortion hyperbolic curve, thus influence speed analysis and iteration effect quality. The static correction study because of the hypsography, the surface low, falls the speed belt lateral change to the earthquake wave transmission influence, and carries on the correction to it, causes the reflected wave distance curve approximately is a smooth hyperbolic curve. Obviously, the correction is still permeated with complex surface area reflection seismic exploration data collection, data processing and interpretation of an extremely essential foundational work.The paper in the complex area surface condition characteristic foundation, has carried on the analysis and the elaboration to the current commonly used static correction method theory, has studied the refraction static correction method technology with emphasis, in the Windows platform, uses C++ and the Fortran language, and has completed complex surface condition static correction system package of research and the development in the foundation which the predecessor worked, the union theory and the actual material, has carried on the test to this system, finally indicated its system the stability and the reliability were high.
