Abstract

The invention provides a seismic prospecting method and device and relates to the field of geophysical prospecting and solves a problem that the prior Patch observation system work methods are in capable of meeting demands. The method includes the following steps: arranging shot points alternatively at shot interval parts between odd-number shot lines and even-number shot lines on a shot-line direction of a Patch observation system and / or arranging alternatively demodulator probes at interval parts between odd-number demodulator probe lines and even-number demodulator probe lines on a seisline direction of the Patch observation system; and according to the arranged shot points and demodulator probes, acquiring seismic data. The technical scheme is applicable of marine seismic exploration and realizes seismic data acquisition of higher precision.

Description

technical field [0001] The invention relates to the field of geophysical exploration, in particular to a seismic exploration method and device. Background technique [0002] Offshore seismic exploration mainly includes two acquisition methods: streamer seismic exploration and submarine cable seismic exploration. During the data acquisition process of streamer seismic exploration, the shot line of the observation system is parallel to the receiver line, the shot point and the receiver point move at equal intervals according to the designed shot spacing, and the common center points formed by the shot point and the receiver point are also equally spaced according to the shot spacing move. Submarine cable seismic exploration data acquisition includes two acquisition methods of parallel and orthogonal observation systems. The parallel observation system is similar to the streamer seismic exploration, the shot line is parallel to the receiver line, and the shot line of the orth...
