Claims (3)

1. Способ непрерывной корректировки двух- и трехмерного сейсмического изображения по глубине при бурении скважины с использованием сейсмической информации о скорости, отличающийся тем, что осуществляют начальное определение модели скорости и последовательную многократную модификацию этой модели путем комбинирования данных, полученных на поверхности, с данными о нижних горизонтах геологической области, полученными непосредственно во время бурения скважины.1. A method for continuously adjusting a two- and three-dimensional seismic image in depth while drilling a well using seismic velocity information, characterized in that the initial determination of the velocity model and sequential multiple modification of this model is carried out by combining surface data with lower horizons of the geological area obtained directly during well drilling. 2. Способ по п. 1, отличающийся тем, что начальную модель скорости определяют в соответствии с методикой начального этапа из анализа сейсмических скоростей и интерпретации. 2. The method according to p. 1, characterized in that the initial velocity model is determined in accordance with the methodology of the initial stage from the analysis of seismic velocities and interpretation. 3. Способ по п. 1, отличающийся тем, что начальную модель скорости модифицируют путем согласования значений скорости в геологических формациях, пересекающих скважину, с моделью сейсмической скорости и экстраполяции этих скоростей по горизонтали и по вертикали на основе структурной интерпретации самого разреза. 3. The method according to claim 1, characterized in that the initial velocity model is modified by matching the velocity values in the geological formations crossing the well with the seismic velocity model and extrapolating these velocities horizontally and vertically based on the structural interpretation of the section.
