Automatic excitation control method and device for seismic excitation source

Abstract

The invention relates to the field of geophysical exploration and development, and in particular relates to a seismic excitation source automatic excitation control method and device. The method comprises the steps that an excitation request signal of an excitation point is received; according to the excitation request signal, the state and the environment noise of a receiving device corresponding to the excitation point are picked up; whether the state and the environment noise meet a preset excitation condition is judged; and whether an excitation command is sent to the excitation point is determined according to the judgment result. According to the automatic excitation control method provided by the invention, man-made time loss is not introduced; through the preset excitation condition, quality judgment is carried out; man-made quality judgment risk is ruled out; the seismic exploration construction efficiency is enhanced; and the seismic exploration quality is improved.

Description

technical field [0001] The invention relates to the field of geophysical exploration and development, in particular to an automatic excitation control method and device for seismic excitation sources. Background technique [0002] In the process of geophysical exploration and development, the operator needs to judge whether the excitation source can be excited to obtain seismic data according to the arrangement state of the field seismic exploration. In production practice, it involves a variety of arrangement states, including: whether it is laid out, whether the power supply is normal, whether the ground equipment itself is working normally, whether the detector connected to the ground equipment is working normally, whether the connecting cable of the ground equipment is working normally, and whether the excitation point corresponds to Whether the total index of the receiving arrangement reaches the threshold value, whether the ambient noise of the receiving arrangement co...

Problems solved by technology

[0003] The current construction process needs to manually judge whether the arrangement state that can be excited each time meets the treatment supervision requirements, and relying on manual construction methods brings two problems: first, the efficiency of excitation determines the efficiency of seismic exploration and production, observe the arrangement state and confirm Operations such as excitation will introduce artificial time loss; secondly, there is a certain quality risk in manual quality judgment, which is likely to cause artificial quality accidents
