径裂爆破是控制爆破在近年发展起来的一个新分支。它与其它控制爆破如:定向爆破、光面爆破、预裂爆破……不同,不但技术先进、工艺新颖、经济合理、施工简便,更主要的是:爆后能够确保被爆之井(孔)壁不发生坍塌,较好地使孔壁围岩保持自身维护能力;能扩展及产生新的径向裂隙,从而增强地下迳流的渗透能力,提高流速,增加流量。这一爆破技术用于油井,可提高出油量,使老井获得新生;
Radial blasting is a new branch developed by controlled blasting in recent years. It is different from other controlled explosions such as directional blasting, smooth blasting and presplitting blasting. Not only the advanced technology, the novel technology, the reasonable economy and the simple construction are more important, the well (hole) wall can be ensured after explosion Without collapsing, it is better to maintain the self-maintenance capacity of the surrounding rock of the hole wall; it can expand and generate new radial cracks so as to enhance the infiltration capacity of subsurface flow, increase the flow velocity and increase the flow rate. This blasting technology used in oil wells, can increase the amount of oil, the old wells get a new life;
