Abstract

The embodiment of the invention provides a seismic data acquisition method and device. The method comprises the steps of acquiring position information of each seismic source on a plurality of measuring lines; determining an excitation mode of each seismic source according to the position information of each seismic source; controlling the vibration work of each seismic source according to the excitation mode of each seismic source, and simultaneously collecting vibration signals generated by the vibration work of each seismic source on the plurality of measuring lines to obtain two-dimensional measuring line data respectively corresponding to the plurality of measuring lines. According to the invention, the seismic data of a plurality of two-dimensional measuring lines can be efficiently collected, the condition of mutual separation between aliasing data is satisfied, and clear and accurate two-dimensional measuring line data are obtained.

Description

technical field [0001] This application relates to the field of geological exploration, and in particular to a seismic data acquisition method and device. Background technique [0002] In the existing two-dimensional seismic acquisition method with vibrators, since the two-dimensional survey line is composed of a receiving line and a very close parallel shot line, a group of vibrators are usually used to excite shots one by one along the direction of the survey line, or two groups of vibrators can be The vibrator utilizes 1 shot line or 2 shot lines with odd and even shot points to excite alternately, or multiple groups of vibrators slide and scan. If it is received by a wired instrument, it is placed and arranged to connect to the instrument with a data cable, and the instrument can obtain the shooting data in real time; if it is received by a node, the recovery node indoor downloads the shooting data. After the construction is completed, a two-dimensional section of the u...
