Description

Technical Field

[0001] The utility model relates to the technical field of electronic detonator detonation time acquisition equipment, in particular to an electronic detonator detonation time acquisition system and a seismic exploration system. Background Art

[0002] Seismic exploration is an important means of geological prospecting for oil, natural gas resources, and solid resources before drilling. It is a geophysical exploration method that uses the differences in elasticity and density of underground media to infer the properties and morphology of underground rock formations by observing and analyzing the earth's response to artificially stimulated seismic waves.

[0003] At present, in the process of geological exploration, it is necessary to use electronic detonators to detonate explosives to accurately create tiny earthquakes, record and collect seismic wave data, and use the seismic wave data to perform geological structure analysis to obtain geological structure data.

[0004] Furthermore, in the process of geological exploration, it is necessary to collect the accurate time TB of the electronic detonator detonation for the post-processing of seismic data. For ordinary electronic detonators, only the accurate time T0 when the detonator starts to initiate the detonation command can be collected. Obviously, there is a delay ΔT between time T0 and time TB. And according to TB1=T0+ΔT, it is calculated, and TB1 is used as the accurate time TB of the electronic detonator detonation. Due to the dispersion of the arrangement of multiple electronic detonators, the delay ΔT of each electronic detonator is different, and in actual engineering applications, ΔT is calculated based on the average delay value of multiple electronic detonators taken from the sampling experimental data. The calculated time TB1 is only an estimated value, not a measured value. The obtained TB1 is essentially different from the accurate time TB of the electronic detonator detonation. It is a serious technical defect for the data acquisition quality in geological exploration, which affects the accuracy of seismic exploration results. Therefore, there is an urgent need for a collection system that is conducive to improving the accuracy of the collected electronic detonator detonation time. Summary of the invention
