人造金刚石深孔钻进,是目前我国发展小口径金刚石钻探技术过程中提出的新课题.我队自1975年推广人造金刚石钻探技术以来,由于地质找矿的需要,施工的钻孔全为800米以上深孔.为了突破和掌握小口径深孔钻进技术,我们利用现有的转盘钻机,在复杂地层条件下,通过实践,初步摸索总结出一套小口径深孔钻进方法,从而使我队钻探生产技术经济指标以较大的幅度超过了同矿区大口径中深孔钻进的历史最高水平.
Deep hole drilling of synthetic diamond is a new task raised in the development of small diameter diamond drilling technology in our country since the introduction of artificial diamond drilling technology in 1975. Due to the need of geological prospecting, Above the deep hole.In order to break through and master the small diameter deep hole drilling technology, we use the existing rotary drilling rig, in complex formation conditions, through practice, preliminary exploration concluded a set of small diameter deep hole drilling method, so that I Team drilling technical and economic indicators to a greater margin than the same area with large diameter drilling in the highest level of the highest level.
