Embodiment 1
[0030] A kind of medicinal powder for preparing microspheres of detonation and detonation in the oilfield layer of the present embodiment is made by uniformly mixing the raw materials of the following mass percentages: 44% potassium chlorate, 6% potassium perchlorate, 4% ammonium nitrate, 36% sulfur powder, and 9% nitrocellulose %, aluminum powder (with a particle size below 10 μm) 0.5%, and magnesium powder (with a particle size below 10 μm) 0.5%.
[0031] The preparation method is as follows: the raw materials of each component are mixed evenly in proportion.
[0032] The method for preparing the explosion-initiated microspheres in the oilfield layer by using the powder of the present embodiment is as follows:
[0033] (1) Get a part of the medicated powder, and add collodion acetone solution therein, stir into a ball and then forcefully sieve with a non-metallic scraper, then sieve, and take a particle diameter of 0.42mm as a qualified product and dry; The add-on of cotton...
