Abstract

The embodiment of the invention provides a seismic exploration method and system. The method comprises the following steps: confirming whether first initiation information broadcast by second controldevices in a specified range is received at present by virtue of a first control device located at a specified shot point position; if the first initiation information is not received, broadcasting second initiation information to all the second control devices in the specified range; after a confirmation message returned by all the second control devices in the specified range is received, shooting the specified shot point when a set shooting moment arrives; and broadcasting shot point shooting information of the specified shot point to all the second control devices in the specified range. The embodiment of the invention can improve seismic exploration efficiency and quality.

Description

technical field [0001] The present application relates to the technical field of geophysical prospecting, in particular to a seismic prospecting method and system. Background technique [0002] In the current field seismic exploration construction process, the encoder of the synchronous control system used to control the point excitation source of the well shot needs to be connected to the instrument host, relying on the analog radio signal transmission and pulse signal to complete the time synchronization with the decoder to ensure The consistency of the firing time of the well shot point and the start time of the instrument acquisition. Among them, the shot point excitation of all explosion groups is generally completed by the instrument operator through the operation of the seismic instrument host. [0003] With the increasingly complex geological exploration targets, the requirements for data acquisition accuracy are getting higher and higher, and the number of seismic ...
