marine seismic data acquisition system and method for its implementation

摘要

method of marine seismic exploration includes towing in the water over the area to be the exploration of at least one u0441u0435u0439u0441u043cu043eu043fu0440u0438u0435u043cu043du043eu0439 braids.containing a number of u0433u0438u0434u0440u043eu0444u043eu043du043eu0432, distributed over the entire length, with an average interval of not more than 500 cm. direct acoustic signals down through the water and into the soil beneath it.take u0433u0438u0434u0440u043eu0444u043eu043du0430u043cu0438 seismic signals reflected from the strata in the ground under water. separately, transforming the digitized output signal of each u0433u0438u0434u0440u043eu0444u043eu043du0430.filtered output signal to reduce the noise present in the output signal, for a signal with reduced noise content.a filtration process is used for the additional input of the digital signal, at least one of the u0433u0438u0434u0440u043eu0444u043eu043du0430. filtering is used to record one sensor to education group.this is to be found to reduce the coherent noise coherence between the length of 20 m or less. this can reduce the noise, the noise u0441u0435u0439u0441u043cu043eu043fu0440u0438u0435u043cu043du043eu0439 braids or waves u0432u0441u043fu0443u0447u0438u0432u0430u043du0438u044f.the application was published, together with the report on the international market.
