Abstract

The invention discloses a high-density high-explosion-speed water gel explosive seismic charge and a preparation method thereof. The high-density water gel explosive in the seismic charge comprises a high energy additive which comprises, by weight, 46-60 parts of paint grade aluminum powder, 31-40 parts of ferrosilicon powder, 4-6 parts of liquid paraffin and 5-8 parts of turpentine. The paint grade aluminum powder and the ferrosilicon powder are added to a mixed solution of the liquid paraffin and turpentine to prepare the high energy additive. The preparation method comprises the following steps: sequentially adding a monomethylamine nitrate solution, ethylenediamine dinitrate, ammonium nitrate and an antifreeze agent under low speed stirring, controlling the temperature at 55-75DEG C, adding a mixture of sodium nitrate and Sesbania cannabina Pers powder, a crosslinking agent and the high energy additive, mixing to prepare the high-density water gel explosive, loading the high-density water gel explosive into a seismic charge housing inserted with a common detonating cord, and sealing to obtain the high-density water gel explosive seismic charge. The high-density water gel explosive seismic charge has the advantages of no containment of toxic substances of TNT and the like, high density, high explosion speed, large unit volume power, safety and environmental protection, certain pressure resistance and antifreeze performance, and simple preparation method.

Description

technical field [0001] The invention relates to a high-density, high-detonation-velocity water-gel explosive source charge column and a preparation method thereof, in particular to a high-density, high-detonation-velocity source charge column for seismic exploration of petroleum and coal fields and a preparation method thereof. Background technique [0002] In oil and coal field seismic exploration, the source charge explodes in the excitation medium to form seismic waves. Seismic waves will be reflected when encountering different geological interfaces in the formation, and the signals of the reflected waves are received by the geophones arranged on the ground, so as to analyze the occurrence of oil or coal seams. According to the buried depth of the oil or coal seam and the conditions of the excitation medium, the source charge is required to have different densities and detonation velocities, which are usually divided into three types, namely, high density and high detona...
