High-energy degradable safe environment-protective seismic explosive column

Abstract

The invention discloses a high-energy, degradable, safe and environment-friendly seismic source charge column, which includes a charge column body and a detonator connected to each other. The charge column body is equipped with a main charge, and one end of the charge column body has an opening and a detonator is arranged at the opening end. , the detonator includes a detonator casing and a metal detonator arranged in the detonator casing, and a metal detonator chamber capable of accommodating the metal detonator is embedded in the powder column. The metal detonator extends into the metal detonator chamber in the powder column body. The material of the metal detonator chamber is corrosive metal. The safety and environmental protection explosive used in the present invention decomposes with substances such as pressurized water, oxygen or microorganisms after the detonator chamber is damaged, so that the explosive loses its explosive performance, and the decomposed products meet the safety and environmental protection requirements. It is developed in response to the safety and environmental protection needs of seismic exploration. The powder column solves the potential safety and environmental protection hazards caused by the non-explosion of the seismic source powder column during the exploration and construction process.

Description

technical field [0001] The invention relates to a special charge for exploration, in particular to a high-energy, degradable, safe and environment-friendly seismic source charge. Background technique [0002] With the further improvement of safety and environmental protection requirements in seismic exploration of oil, natural gas, and coal resources, the explosive source grains used in seismic exploration are all shells made of non-degradable polyethylene plastics. There are a series of technical performance indicators and cost requirements for the use of seismic source grains. The use of high-molecular polyethylene plastics in manufacturing is low in production cost, mature in production technology, and simple and reliable in technology, so it is widely used. As we all know, polymer polyethylene plastics take a long time to degrade. When the explosive is in a completely sealed environment, there is no other substance that can neutralize or react with it, and the expiry dat...

Problems solved by technology

[0003] The existing technologies in this field are mainly polymer polyethylene plastic shells and rarely used metal (steel) shells with high production costs, which take a long time to degrade and cannot meet the safety and environmental protection needs of current and future seismic exploration.

In the domestic existing technology, the application number / patent number of "water gel explosive seismic source charge column" is 03282513, which involves environmental protection issues, but it refers to "water gel explosive"; the patent number of "degradable safe and environmentally friendly seismic source charge column" is: ZL 200920029939.5 mainly adopts the combination of paper and plastic, but the manufacturing process of the shell is cumbersome; after searching the Internet and consulting in the field of domestic geophysical prospecting, no use of similar technical products and related protected intellectual property rights have been found
