Abstract:
It is still a world-class problem to carry out seismic operation in the limestone area due to the development of karst cave and lithologic density,which cause poor excited condition and great change of energy.To obtain good seismic data in such an exposed area of limestone,seismic exploration workers have been making a lot of effort,trying a variety of methods to solve this problem,but still not breakthrough in nature.In Middle Guangxi limestone area,such new methods as innovative operation technique,tackling key problems have been applied with new technology of observation system of three line two shots wide line,and the obvious effect of exploration was made.
