绳索取心液动潜孔锤钻进技术在利比里亚邦山铁矿详查中的应用与探索

Application of Wire-line Coring Hydro-hammer Drilling in Iron Ore Prospecting in Liberia and the Exploration

摘要:

绳索取心液动锤技术集绳索取心技术与液动潜孔锤技术优势于一体，可比普通绳索取心钻进提高纯钻速30%～150%，在坚硬、脆性、“打滑”地层中钻进效果更为明显。介绍了绳索取心液动潜孔锤钻进技术在利比里亚邦州邦山铁矿详查中的应用情况，并对其应用效果进行了分析讨论。

Abstract:

Combined the wire-line coring and hydro-hammer technologies, the drilling speed of wire-line coring hydro-hammer technology increases 30%～150% than that of traditional wire-line coring drilling, especially in hard, brittle and slipping formations. The paper introduced the application of wire-line coring hydro-hammer technology in Liberia and discussed the application effects.
