Abstract

The invention discloses a high-density high-detonation-velocity water-resistant seismic explosive column, which comprises a seismic explosive column shell, wherein a filling explosive, a main charge, an initiating explosive and a detonator base, wherein the filling explosive, the main charge and the initiating explosive are sequentially filled in the inner cavity of the seismic explosive column shell from front to back, the detonator base is arranged at the rear end of the seismic explosive column shell and used for detonating the initiating explosive, the mass percent of the main charge in the seismic explosive column is 60-75%, the mass percent of the initiating explosive is 15-30%, the mass percent of the filling explosive is 10-15%, the filling explosive is an emulsion explosive, the main charge is a retired double-base grain, and the initiating explosive is a modified double-base grain. According to the seismic explosive column and the seismic explosive column with the retired double-base propellant explosive column as the main charge, the problem that an existing seismic explosive column is low in density is solved, an efficient utilization approach is provided for batch treatment of the retired double-base propellant explosive column, the environmental problem caused by destruction of the retired double-base explosive column is avoided, and the seismic explosive column conforms to the environmental protection development direction.

Description

technical field [0001] The invention relates to a high-density, high-explosion-velocity water-resistant seismic source charge column, which belongs to the technical field of seismic source charge column. Background technique [0002] The source charge is a blaster that generates seismic waves through the explosion of explosives. It is mainly used for geophysical exploration of oil and natural gas and deep-water reef breaking operations, and has a large market demand. The source grain can be divided into three types according to the density: low density, medium density and high density. The density of the double-base propellant is 1.6g / cm3, and it can detonate reliably under the action of detonation energy. The detonation velocity can reach more than 7000m / s, and the detonation transmission is stable. It is an ideal energetic material for the main charge of high-density seismic source charges. [0003] The existing source charge is composed of shell, priming charge and main ...
