With the deepening of geological and mineral exploration,deep-hole drilling often encounters many sets of complex formations,which require high drilling quality and increase the difficulty of construction.In view of the difficult problems of drilling construction in the exploration stage of the Gaodi Man-ganese deposit in Songtao county of Guizhou province,through the joint application of'One-base-two-hole'hole arrangement and construction technology,cement sealing hole wall protection technology,drilling hole structure optimization anti-collapse burying drilling technology,multimeasures anti-deviation technology,drilling fluid circulation difficult treatment technology,drill pipe tripping treatment technology,casing burying drilling treatment technology.A set of deep-hole drilling technology system at exploration stage has been formed,which can be used for reference for similar projects in the future.
