Abstract

The invention discloses an activator applied to a carbon dioxide fracturing device. The activator is prepared from the following ingredients in parts by weight: 30 to 60 grams of potassium perchlorate, 10 to 18 grams of salicylic acid, 7 to 18 grams of ammonium oxalate, 6 to 12 grams of sodium fluoride, 6 to 12 grams of charcoal powder, 3 to 6 grams of oxalic acid, 4.5 to 7 grams of superfine aluminum powder and 5 to 7 grams of superfine magnesium powder. The activator has stable performance, cannot be lighted or detonated by open fire in air, can prevent impact, can prevent combustion or explosion caused by collision or high-altitude falling and has safety and reliability; the activator can be efficiently utilized in a fracturing pipe through liquid carbon dioxide even ambient pressure; in addition, a formula can be adjusted according to need within the above range, so that the reaction speed of the activator can be adjusted.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide crackers, in particular to an activator for carbon dioxide crackers. Background technique [0002] The carbon dioxide cracker is to fill a certain quality of liquid carbon dioxide into the cracking tube, use the detonator to quickly stimulate the activator, and the liquid carbon dioxide will gasify and expand instantly, and generate high pressure. The high-pressure gas is released from the relief device and acts on the coal (rock) body to achieve the purpose of expanding and fracturing the rock and coal seam. [0003] The activator is installed in the main body of the cracking tube to provide heat energy for the phase change gasification of liquid carbon dioxide. the process of. When in use, the ignition head is ignited by exciting the current, the activator is ignited and burns rapidly and releases a large amount of heat, the carbon dioxide in the main pipe of the cracker is transformed ...
