SEISMIC EXPLORATION METHOD IN REGIONS WITH SEVERE HYDROGRAPHIC CONDITIONS Russian patent published in 2011 - IPC G01V1/00 

FIELD: mining.

SUBSTANCE: at the specified configuration of river system there pre-set is three-dimensional grid of "source-receiver" symmetry points, which is required to build up three-dimensional model of environment. Location scheme of ashore seismic receiver is estimated considering the arrangement of vibration sources along the bed of the river or in the group of estuary branches. Excitation of elastic vibrations is performed in river by means of the above sources and their recording is performed by means of ashore seismic receivers. Then, areal processing bases are chosen around each specified point of "source-receiver" symmetry. For each base there formed is the set of seismic routes relative to points of "source-receiver" symmetry of the grid. Each set of seismic routes is subject to three-dimensional directed summation at those points. At that, location scheme of seismic receivers is designed on the basis of the specified stacking fold in areal processing bases without restrictions in relation to azimuths and offset distances.

EFFECT: realisation of the method is simplified and accuracy of the obtained results is improved.
