Abstract

The invention relates to an explosive, in particular to a main charge for charging of an emulsified seismic explosive column used in the field of seismic exploration. According to the technical scheme, the main charge for charging of the emulsified seismic explosive column is prepared from, by weight, 74 parts of ammonium nitrate, 9.5 parts of sodium nitrate, 9.5 parts of water, 7 parts of a composite oil phase and 2.3 parts of perlite, wherein the perlite accounts for 2.3% by weight of a matrix. The main charge adopts a pure physical sensitizing technology, and therefore the problem that the changing and unstable density of the main charge cannot be controlled due to the fact that the seismic explosive column charged through chemical sensitizing is subjected to environmental changes is solved; meanwhile, the adjustment of charge component proportion follows the zero-oxygen principle of explosive design, and the best combination of performance indexes required for exploration is also achieved, and the detonation velocity is up to 5300-5500 m/s. The main charge is simple in formula, large in brisance, stable in storage, long in storage time, harmless to human bodies and environment and low in cost.

Description

technical field [0001] The invention relates to an explosive, in particular to a main charge of a seismic source charge column used in the field of seismic exploration. Background technique [0002] Seismic exploration refers to a method of artificially simulating earthquakes to generate seismic waves, and obtaining geological structures by receiving echo information from the inside of the bottom layer, so as to judge and find structures that may contain target objects. It is an important means of finding energy. Explosive seismic source has many advantages such as strong energy, wide frequency band, and ability to pass through relatively deep formations and rock formations. Currently, it is still the main source form used in petroleum and seismic exploration. [0003] Since the invention and use of the seismic source powder column, the main charge has been ammonium-ladder explosives, but ammonium-ladder charges have caused serious damage and pollution to operators and the e...
