Description

Technical Field

[0001] The utility model relates to an electronic detonator, in particular to an electronic detonator for seismic exploration. Background Art

[0002] Seismic exploration is to stimulate elastic waves (seismic waves) in the rock mass by artificial methods (using explosives or other energy sources), and use seismic exploration instruments to detect the vibration of the earth at different positions along the lateral line. The detection information is recorded on a magnetic tape in the form of data, and processed by a computer to extract valuable information. As seismic waves propagate in a medium, their path, vibration intensity and waveform will change with the elastic properties and geometric form of the medium. By mastering these changing laws and based on the time course and speed data of the received waves, the propagation path of the wave and the structure of the medium can be inferred. Based on the parameters such as the amplitude, frequency and wave velocity of the wave, it is possible to infer the properties of the rock, thereby achieving the purpose of identifying the geological structure and prospecting for minerals. At present, seismic exploration has become one of the most effective methods in oil exploration.

[0003] Seismic exploration detonators are mainly used to trigger seismic waves and are one of the most important tools for oil exploration. By detonating the detonator, the explosives are detonated to produce an explosion reaction, generating seismic waves. By setting up multiple seismic exploration detonators, a series of seismic waves can be generated, and the reflected waves of underground materials can be obtained, and then the distribution of underground rock layers, minerals and other materials can be analyzed to provide assistance for geological exploration.
