1. Способ определения координат забоя скважины путем регистрации акустических сигналов, отличающийся тем, что сейсмоприемник устанавливают в забой скважины, а для определения координат забоя измеряют время распространения акустических сигналов, возбуждаемых импульсным источником на дневной поверхности в районе устья скважины из точек с известными координатами.1. The method of determining the coordinates of the bottom of the well by recording acoustic signals, characterized in that the seismic receiver is installed in the bottom of the well, and to determine the coordinates of the bottom, measure the propagation time of acoustic signals excited by a pulsed source on the surface at the wellhead from points with known coordinates. 2. Способ по п.1, отличающийся тем, что координаты забоя скважины вычисляют по формулам:
