The Application of Seismic Interferometry in Oil and Gas Geological Survey on the Periphery of Songliao Basin

Abstract

Seismic data collected in volcanic rocks coverage area has weak energy and low signal to noise ratio. These characteristics cause severe problems for seismic exploration. Many geophysicists try to solve these problems and propose many methods. Some of them focus on the acquisition method to improve the signal to noise ratio of data in the step of data acquisition. The others focus on the processing method to improve the data .In this paper, we focus on the processing method and try to apply the seismic interferometry to volcanic rocks coverage collected on the periphery of Songliao Basin to improve the signal to noise ratio and the resolution.
