The Phase Location of Reflected Seismic Pulses

An original technology for locating instantaneous phases of reflected seismic pulses is proposed. In order to construct high resolution seismic images the technology uses statistical radio-engineering methods for solving problems of optimal reflected pulses reception. Based on detecting and locating reflected seismic pulses phases the technology allows constructing wave lineups even in conditions of low quality field material. The technology allows reliably determining location of several phase reference marks for the same reflected seismic pulse that improves possibilities for tracing reflected waves lineups. Increasing the number of reflected seismic pulses, revealed on seismic traces, increases the number of wave lineups on gather that increase resolution of temporal section. The achieved high resolution of the temporal section contributes to solving further problem on determination of earth medium depth structure, i.e. on construction of higher resolution seismic images of depth sections. Such images ensure reliable determination of closely located reflecting horizons. The proposed locating technology has number of advantages compared with known seismic images constructing technologies because it does not use procedures distorting complex spectrum of received signals.
