庐枞LZSD-1孔科学钻孔钻头选择与使用

受中国地质科学院地质研究所的委托,安徽省地质矿产勘查局313地质队承担《华东庐枞盆地科学钻探选址预研究》3000m科学钻探工程任务,该钻孔为大陆科学钻探选址预研究项目中6个钻孔之一,主要目的是通过钻探揭示和验证与成矿有关的岩体、基底、盖层的空间分布,建立地壳结构模型和异常解释的标尺,为大陆万米钻探提供选址依据。本文主要介绍了在施工过程中的钻头选用情况,仅供同行参考。

ChoiCe And uSe of drill bit for SCientifiC drillinG of hole lzSd-1 in the lu-zonG AreA

Commissioned by Institute of Geology of Chinese Academy of Geosciences, No.313 Unit of Bureau of Geology and Mineral Exploration of Anhui Province undertook 3000m scientific drilling for Pre-study of Scientific Drilling Site Selection in the Lu-Zong Basin of East China, which is one of 6 of its kind in continent, aiming to disclose and test spatial distribution of rock masses, basements and overburdens concerning ore formations, establish a crustal structure model and a scale for anomaly interpretation, providing a basis for site selection of continental 10000m drilling. This paper introduced the use of drilling bit in construction only for reference by our peers.
