METHOD OF UNINTERRUPTED CORRECTION OF TWO- AND THREE-DIMENSIONAL DEEP SEISMIC IMAGE WITH USE OF SEISMIC INFORMATION ON SPEED WHILE HOLE IS DRILLED

摘要

mining industry. SUBSTANCE: initial determination of model speed and subsequent multiple modification of this model speed are conducted with the aid of combination of geophysical data. Data obtained on the ground and data on lower horizons generated directly in process of hole drilling are used. EFFECT: increased accuracy of control over phases of drilling. 2 cl, 5 dwg
