The embodiment of the application provides a method and apparatus for locating a seabed detection point. The method comprises: acquiring a preset number of coordinates within a preset range of an initial coordinate of a target detector; on the basis of a preset number of calibration time differences calculated by the preset number of coordinates, carrying out linear dynamic correction processing on common-receiver-point gather seismic data of the target detector to obtain an estimated number of common-receiver-point gather corrected seismic data; carrying out superposition processing on directwave data among the estimated number of common-receiver-point gather corrected seismic data to obtain a preset number of direct wave superposed data; and calculating mean squares of the preset numberof direct wave superposed data respectively and determining a detection point coordinate of the direct wave superposed data corresponding to the largest mean square as the coordinate of the target detector. Therefore, the actual coordinate of the detection point can be accurately determined.
