Abstract
The invention provides a seismic exploration excitation point identification device and identification method, and relates to the technical field of seismic exploration. The device comprises a reflective film, a color flag, and a flagpole, wherein the reflective film and the color flag are both fixed in the flagpole; the reflective film is arranged at the top end of the flagpole; the color flag isfixed below the reflective film; the color flag is longer than the reflective film; the reflective film is used for positioning an excitation point through reflection in seismic exploration; and a character area is arranged on the color flag, and characters in the character area are used for recording attributes of the excitation point. By means of the reflective film and the color flag which arearranged in the identification device, the visibility at night is improved, the problem that in the prior art, measurement point identification is not clear is solved, the seismic exploration positioning time is shortened, and the seismic data collection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a marking device and a marking method for seismic prospecting excitation points. Background technique [0002] When conducting seismic exploration, it is necessary to collect data in the field. First, the measurement work of the excitation point and the receiving point must be carried out. The measurement work is usually to carry out the field setting out of the excitation point and the receiving point on the construction deployment map of the seismic exploration through the measurement equipment according to the requirements. Mark the measuring point with the measurement identification flag to complete the measurement and positioning. Since environmental noise is an important factor affecting seismic exploration construction, in order to avoid or reduce the impact of environmental noise, seismic data acquisition is often carried out at night, and the measurement and ...
