UDC 550.834.05:[(552.54+552.578.2.061.43):551.72] GESSENTIALLY NEW OPPORTUNITIES OF MULTIWAVE SEISMIC EXPLORATION
Based on the complex analysis of multiwave seismic exploration (MWSE) data, in-situ measurements, petrophysics, physical, mathematical modeling and theoretical works it has been possible to formulate and prove the technique for vertical jointing delineating zones of in carbonate rock beds. It is established that it is possible to determine jointing parameters and pore filler properties by Poisson’s ratio determined by interval times of longitudinal and transverse converted waves of 2D-3C seismic exploration data. The use of different types waves of and their polarization opens up possibilities to define anisotropic characteristics of rocks not at a qualitative but at a quantitative level. A way to calculate Poisson’s ratio values in the Riphean part of the section, which hasn’t been drilled in, is also considered. The approach is based on transition from interval times to TPP, TPS time derivates along x-coordinate (lateral ranging).
Key words: multiwave seismic exploration, Poisson’s ratio, vertical jointing, Riphean, Vendian, Usolskaya Formation.
