SPACE-SEISMIC-FACIAL METHOD OF CONSTRUCTION OF BLOCK MODEL OF GEOLOGICAL STRUCTURE OF SEDIMENTARY COVER Russian patent published in 2010 - IPC G01V9/00 G01V1/00 G01V11/00 

FIELD: mining.

SUBSTANCE: during the decoding process of air-space-snapshots there are extracted liniments. It is analysed its deep reflection at temporal vertical seismic profiles. It is mapped system of vertical in plane rectilinear sub-parallel oriented in sub-meridional, sub- latitudinal, northwestern and northeastern directions of disruptive -flexural disruptions. They are divided for each structural level for consedimental and post- sedimentological. By consedimental disruptions there are drilled out seismic facies, and also border structurally - facial zones, in the range of which it is installed corresponding of seismic facies to geological facies. There are extracted facies, allowing collecting properties. There are outlined borders of structural and non-structural traps, most favorable for drilling location oil and gas exploration and production wells.

EFFECT: creation of reliable model of geology of sedimentary cover ensured by more accurate definition of position of productive stratums and more accurate definition of boundaries of hydrocarbons beds.
