| titleOfInvention | METHOD OF MARINE SEISMIC EXPLORATION WITH FORMATION OF SEISMOGRAMS FROM FACTIVE SOURCES |
| abstract | 1. The method of marine seismic exploration, characterized in that the elastic vibrations are excited many times at different zenith angles relative to the points of reception in air, in water or on a solid floating on the surface of the water, elastic vibrations are detected by sensors located at the bottom of the water basin or inside the elastic half-space, and stored in digital form, characterized in that, in order to improve the signal-to-noise ratio, seismograms are generated for fictitious sources located at different points of reception, by summing the records in each seismic receiver with leading delays equal to the travel times from the actual vibration sources to the selected fictitious sources, controlled by the time of recording the first entry at the location of the fictitious source. 2. The seismic survey method according to claim 1, in which only those whose removal is less than a predetermined distance are additionally selected from real sources. The seismic acquisition method according to claim 1, in which, in addition, for the formation of each seismogram from a fictitious source, only sensors are selected whose removal from the fictitious source is in a predetermined range. The seismic survey method according to claim 1, in which additionally fictitious sources are placed at the location of the sensors in order to control and correct the travel time from the real source to the fictitious. The seismic survey method according to claim 1, in which additional records from real sources are summed with weights proportional to the amplitude of the wave entering the sensor located at or near the location of the fictitious source.
