Abstract
During the acquisition of “two widths and one height” seismic data in the Songliao Basin, the external interference waves generated by the windmills were clearly recorded at the same time. Their strong energy and wide frequency band seriously affected the data and imaging quality. It is difficult to effectively suppress by the traditional noise suppression method, and we must find an effective method. Based on the actual “two widths and one height" seismic data, this paper analyzes the generation mechanism and characteristics of external interference waves in detail, and studies the fitting of external interference waves based on f-x domain predictive filtering, and achieves the external interference waves suppressed by matching and subtraction. The application effect of actual data shows that this method can better suppress external interference, and maintain the relative amplitude relationship and spectral characteristics of seismic signals, improve the data fidelity, and lay a good foundation for the subsequent fine seismic data processing.
