Scan control method and device for vibroseis

Abstract

The application provides a scan control method and device for the vibroseis. The method includes: issuing status inquiry information by using a radio station for the current vibroseis, wherein a communication distance of the radio station is greater than or equal to a simultaneously excitable distance of the vibroseis; receiving status information fed back by the vibroseis within the communicationdistance range, wherein the status information includes position information of the vibroseis, an excitation state, and the time to be excited; and acquiring a scanning distance between the current vibroseis and the vibroseis currently being scanned, and controlling the current vibroseis to perform excitation scanning according to the scanning distance. With the embodiments of the application, the production mode that requires the control of the host of the seismic instrument has been changed into the mode that the local group is confirmed to be excited. The excitation accuracy is improved, the advantages of node devices can be played, and the production efficiency is greatly improved.

Description

technical field [0001] The application belongs to the technical field of seismic data acquisition, and in particular relates to a scanning control method and device of a vibroseis. Background technique [0002] In the process of seismic exploration and production, usually a vibroseis can be used to excite seismic waves, and instruments such as geophones can be used to collect seismic data. At present, there are many efficient excitation methods for vibrators, such as: alternate scanning without waiting for listening time, sliding scanning with sliding time directly set, and synchronous sliding scanning with real-time judgment of the distance to the source to be excited. Regardless of the excitation method, it is necessary to use the radio station to communicate with the central control system, and the central control system controls the excitation of the vibrator. [0003] The higher the production efficiency, the greater the amount of data transmitted by the data station, ...

AI Technical Summary

Problems solved by technology

[0003] The higher the production efficiency, the greater the amount of data transmitted by the data station, and the limitations brought by the communication distance and bandwidth of the station will affect the production efficiency more and more.

Especially in some areas, in order to make the communication distance of the instrument host cover all the source groups, it is necessary to set up multiple radio relays. The additional delay and communication obstruction become the bottleneck restricting the improvement of production efficiency.
