Description
При симметричных услови х взрыва в неограниченной среде возникают лишь продольные волны. Описываемый способ относитс к разработке эффективных методов возбуждени поперечных волн в св зи с развитием новой модификации сейсмической разведки.Under symmetric explosion conditions in an unlimited medium, only longitudinal waves arise. The described method relates to the development of efficient methods for the excitation of transverse waves in connection with the development of a new modification of seismic exploration.
Основным условием возбуждени поперечных сейсмических волн вл етс необходимость применени источника направленного действи . Однако еще не имеетс эффективных способов возбуждени .поперечд1ых сейсмических волн. Известные способы ограничиваютс применением различного рода ударов по поверхности почвы и асимметрии в поле взрыва. Недостат-ками известных способов вл ютс примитивность и недостаточна мощность (удары по почве), а также слаба эффективность (способы создани асимметрии в поле взрыва).The main condition for transverse seismic wave excitation is the need to use a directional source. However, there are still no effective ways to excite seismic waves. Known methods are limited to the use of various kinds of impacts on the soil surface and asymmetry in the field of explosion. The disadvantages of the known methods are the primitiveness and insufficient power (impacts on the soil), as well as poor efficiency (methods of creating asymmetry in the field of explosion).
В предлагаемом способе эти недостатки устран ютс тем, что вблизи ОТ пункта взрыва предварительно создают искусственную обнаженную вертикальную поверхность путем рыть канавы с вертикальной стенкой / и Т. п. или же.образуют камуфлетную полость 2 взрывом в соседней скважине. При наличии вблизи от взрываемого зар да ВВЗ свободной поверхности (см. чертеж) возникает направленный взрыв, так как основна часть энергии взрыва распростран етс в направлении от зар да к свободной поверхности. Возле свободной поверхности могут производитьс взрывы не ТОЛЬКО единичных зар дов, но и групп зар дов . Дл наиболее эффективного использовани энергии взрыва зар ды ВВ следует располагать против середины свободной поверхности. В этом случае свободна энерги взрыва будет распростран тьс по кратчайшему рассто нию в горизонтальном направлении,, перпендикул рном свободной поверхности, что и удовлетвор ет условию эффективного возбуждени поперечных волн. Сейсмоприемники дл регистрации поперечных волн должны располагатьс на пр мой линии, касательной или параллелцюй. плоскости свободной поверхности.In the proposed method, these disadvantages are eliminated by the fact that near the OT of the explosion point, an artificial bare vertical surface is created by digging vertical wall ditches I and so on, or else a camouflet cavity 2 is formed by an explosion in an adjacent well. When there is a free surface in the vicinity of the explosive VVZ charge (see drawing), a directional explosion occurs, since the main part of the explosion energy propagates in the direction from the charge to the free surface. Not only single charges, but also groups of charges can be exploded near the free surface. For the most efficient use of the explosive energy, explosive charges should be placed against the middle of the free surface. In this case, the free energy of the explosion will propagate over the shortest distance in the horizontal direction, perpendicular to the free surface, which satisfies the condition for the effective excitation of the transverse waves. Seismic receivers for registration of transverse waves should be located on a straight line, tangential or parallel. plane free surface.
