    摘要:

    严重漏失、垮塌地层快速钻进工艺的研究与应用是当前固体矿产勘查地质岩心钻探亟需解决的问题之一。文章结合甘肃阳山金矿钻探工程实践,针对长孔段的严重漏失、垮塌地层,总结了一套适用于该矿区快速勘探的绳索取心钻进和全面钻进、顶漏钻进工艺,采用水泥临时封堵、套管封堵、扩孔、跟管等方式进行封堵的钻进方法,分析了其应用效果,提出了在该地层钻进的认识与思考,以期为同类型地层钻探提供参考。

    Abstract:

    The research and application of rapid drilling techniques for drilling through severely permeable and collapsed formations is one of the urgent issues to be addressed in solid mineral exploration geological core drilling. Combined with the practice of drilling engineering in Yangshan gold mine in Gansu Province, in view of the serious leakage and collapse of the long hole section, this article summarizes a set of drilling techniques suitable for rapid exploration in this mining area, which includes wire-line core drilling and full-hole drilling blind drilling technology used to quickly passing through the formation, and cement temporary plugging, casing plugging, reaming, following pipe used to plug the formation,and analysis their application effects. At last, the understanding and thinking of drilling in the formation were proposed. This article is intended to provide a reference for drilling in similar formation.
