Problems solved by technology

Most of the liquid explosives currently used in the exploitation of oil and gas reservoirs are sensitized by high-energy explosives, which have a high detonation velocity, are difficult to control, and have certain damage to the wellbore. Most of the high-energy explosives still exist in solid form, and the distribution of the system is uneven. The energy density is uneven, and the cost of high-energy explosives is relatively high; the explosives used in explosive welding mainly include expanded ammonium nitrate explosives, pow

Abstract

The invention relates to a medium-low detonation velocity liquid explosive and a preparation process thereof. The liquid explosive comprises the following components by mass: 45-88% of a liquid explosive, 1-6% of an adhesive, 2-7% of a sensitizer, and 9-42% of water-absorbent resin. The medium-low detonation velocity liquid explosive has the following advantages: (1) the energy density of the liquid explosive is diluted, and the detonation velocity of the liquid explosive is reduced; (2) the detonation velocity is easy to control and convenient to adjust, all components in the system are uniformly distributed, and energy density is uniform; (3) the detonation is reliable, the detonation velocity is easy to control, mechanical sensitivity is low, and the safety is high; (4) a large amount of water is brought into the liquid explosive and mixed uniformly, the explosion temperature generated during explosion is reduced, and water mist generated during explosion absorbs generated harmful gas and dust; and (5) the operation is convenient, the preparation method is simple, and the use cost is reduced.

Description

technical field [0001] The invention is a medium and low detonation velocity liquid explosive, which belongs to the explosive formula and its preparation process Background technique [0002] Liquid explosives are cheap, easy to prepare, powerful, easy to fill, and can change their shape arbitrarily. For some spaces that are inconvenient to fill with solid explosives, liquid explosives can fully overcome their shortcomings and fill them better. They are used in many engineering blasting or research projects. It is widely used in deep hole blasting, geological exploration, micro-blasting, explosive welding, oil and gas reservoir exploitation and so on. Most of the liquid explosives currently used in the exploitation of oil and gas reservoirs are sensitized by high-energy explosives, which have a high detonation velocity, are difficult to control, and have certain damage to the wellbore. Most of the high-energy explosives still exist in solid form, and the distribution of the ...
