Abstract

The article tells about the way of eliminating the neighboring source positions interference when carrying out field seismic works by Slip Sweep method. The principle of struggle with disturbance is based on frequent filtration of the received signal on the stage of obtaining vibrorecords to slip sweep convolution. Since the interference from neighboring SP is artificial with known parameters, therefore it is predictable. Using this property and applying the time-variable frequent limit filter (tracking filter) the author was able to suppress the wave-interference significantly pointing out the useful signal. In addition, irregular waves-interference (microseisms) are removed. This method allows increasing vibroseis source productivity in several times not only without quality deterioration, but also with improvement compared to Flip flop standard method
