我队地震勘探试工区,地形起伏,灌木丛生,稻田遍布,交通十分不便。以往施工以WT-2型物探钻机打钻为主,这种钻机,机体笨重,劳动强度大,破坏农作物严重,个别区段地层坚硬或因流砂层,钻孔深度无法保证。尤其是开展多次迭加方法施工时,炮井需要量成倍增长,严重地影响了施工速度。为此,我队开展了定向聚能爆炸地震震源试验。 I team seismic exploration pilot area, topography, shrubs, paddy fields all over, traffic is very inconvenient. In the past, drilling was mainly carried out by WT-2 geophysical drilling rig. The drilling rig was heavy and labor-intensive. It damaged the crops seriously. The stratum of some individual sections was hard or could not be ensured due to the flowing sand layer. In particular, when carrying out the construction with multiple superimposition methods, the need for shotcreting has doubled and the construction speed has been severely affected. To this end, our team conducted a focused gather explosion earthquake source test.
