Corrección estática de una línea sísmica en la zona de los llanos orientales de Colombia empleando el método de elevación con el software crewesmatlab.

Abstract

Seismic data processing is the basic part of the analysis and interpretation of field data generated by seismic exploration, and its purpose is to determine the location of minerals and hydrocarbons. Due to various factors in the field of research, until today, the acquisition of seismic information has limitations in its quality and precision, such as the topography and composition of the subsoil strata, so it is necessary to use computer tools to improve this information. This is essential for the proper functioning of any project that involves the identification of the composition of the subsoil, its characteristics and distribution. This monograph aims to develop seismic data processing and implement the CREWESMATLAB analysis software to generate static corrections, with the aim of homogenizing the existing terrain and subsoil, in this case, the seismic lines located in the eastern plains of Colombia. Mountain Wool). In seismic exploration, the primary and secondary waves (P and S) generated by explosive explosions pass through different layers of soil and are then recorded on a geophone to achieve their characterization. The geophone reads time and speed, intensity, amplitude, etc., although the data recorded by others is true, it is far from the data obtained under ideal but non-existent conditions; Because the trajectory of these waves is affected by the changes in density between the various materials and strata that exist in the subsoil, and the difference between the detonator and geophone levels. Elevation or reference surface methods are used to statically correct the information capture time by calculating the replacement rate and assuming the reference surface as the reference point to generate a homogeneous model. Therefore, relevant methods should be proposed to correct these data and allow the generation of high-quality Ape Cut Images, to facilitate further analysis and explanation. There are several tools and software that can implement full seismic processing, but they are difficult to access e to their private or paid nature, unlikefree-to-use tools; CREWES MATLAB Software Library (CMLS), Provides a code library that can be run in MATLAB software The catalog allows processing of seismic data, but it is necessary to evaluate the excitability and convenience of the code and determine its feasibility in subsequent projects on this basis.
