METHOD OF RECORDING SEISMIC SIGNALS TO SEARCH AND EXPLORE HYDROCARBONS IN STRUCTURES OF UNDERWATER GEOLOGICAL ARRAYS

摘要

FIELD: physics.;SUBSTANCE: method for recording seismic signals to search for and explore hydrocarbons in the structures of underwater geological arrays, according to which seismic waves are recorded, including responses in water from the PS- and SS-waves reflected from inhomogeneities in the underwater geological arrays and generated by the seismic wave source, by means of receivers located in the water layer, and analyzing the temporal recordings of the signals is performed, by the results of which the investigated underwater geological arrays are judged. Herewith the receivers are positioned near the water surface and are removed from the source by a minimum predetermined distance, which makes it possible to record the responses in water from the PS- and SS-waves, which is determined by full-wave numerical modeling based on the known bottom relief data and/or thickness of the water layer, and/or the investigated underwater geological array.;EFFECT: reducing the labour intensity, technical and technological complexity of work with simultaneous increasing the informative nature of seismic studies.;3 cl, 4 dwg, 1 tbl
