METHOD OF EXCITATION OF ELASTIC VIBRATIONS IN PERFORMING PROSPECTING JOBS

摘要

FIELD: seismic prospecting. SUBSTANCE: method of excitation of elastic vibrations in performing prospecting jobs consists in forming and exploding continuous charges consisting of separate filaments. Adjacent filaments are exploded at time intervals which form together party-check sequences selected by the law of random and prime figures. Maximum magnitude of rated cross-correlated functions of party-check sequences of linear charges does not exceed 0.4. Adjacent filaments are located at distance which excludes initiating of explosion of adjacent filaments. Each filament of each charge is provided with lateral screens. EFFECT: high informativity and geological and geophysical efficiency of prospecting jobs. 3 cl, 1 dwg
