Site Disposal Technology in Loess Tableland
Sinopec North · Chinese Journal of Engineering Geophysics · 2011
Serious statics correction problem caused by complex seismic and geological conditions in Loess Tableland troubles the site seismic work there.This paper analyzes the interference waves in seismic records from Loess Tableland and identifies the characters of various types of interference waves aiming at the features of seismic data in this area and the actual situation in site disposal.Then the features of seismic data in Loess Tableland are analyzed through site disposal examples.Pre-stack de-noise processing and chromatography method are used to further suppress the interference waves and to solve surface statics correction problem respectively.Under the seismic data site disposal workflow,processing parameters are chosen carefully to improve signal-noise ratio effectively and so to achieve an ideal result.
