一种新型炸药震源—地面定向震源弹的应用效果,孙景旺马家滩掩冲构造带位于陕甘宁盆地西缘断褶带的中段,地表大面积出露老地层,岩石坚硬、钻井困难,采用井炮生产,效率低、成本高。由于地形复杂,使用可控震源也受到限制。近年来采用导爆索激发,收效也不大。一九八五年采用地面定向震源弹和导爆索串联激发收到了较好的效果。定向震源弹外形是钟状,顶端启爆药柱设有启炸孔,启爆药柱下方为复合药柱,药柱内侧为聚能穴,穴为倒漏斗形,塑料外壳,每发装药量为0.5至1.0kg。导爆索爆炸也有明显的方向特性。定向震源弹和导爆索串联激发既能起到组合爆作用,又具有明显的方向性和聚能性,从而达到增强有效波、压制干扰波
The application effect of a new type of dynamite source-ground directed source projectile, the Sunjianwang Majiabang masking belt lies in the middle section of the western margin of the Shan-Gan-Ning basin and shows a large area of exposed old formations with hard rock and difficult drilling. Wells production, low efficiency, high cost. Because of the complex terrain, the use of vibrators is also limited. In recent years the use of detonating cord excitation, the effect is not large. In 1985, the use of ground-based source bombs and detonating cord series excitation received good results. Directional projectile projectile shape is bell-like, the top of the detonating explosive column has a hole, the bottom of the detonating drug column for the compound drug column, drug column inside the poly energy points, points for the inverted funnel shape, plastic shell, each charge The amount is 0.5 to 1.0 kg. Detonation cord explosion also has obvious directional characteristics. Directional source projectile and detonating burst in series can not only play the role of combined explosion, but also has obvious directionality and energy, so as to enhance the effective wave, suppress the interference wave
