SYZX绳索取心液动锤在小秦岭金矿田复杂地层深部钻探中的应用

Application of Wire-ling Coring Hydro-hammer in Deep Drilling in Complex Formation of Xiaoqinling Gold Field

摘要:

小秦岭金矿田南、北矿带深部找矿钻探施工中，应用SYZX绳索取心液动锤钻进技术，对深孔钻进采取防斜保直钻进，为钻孔的顺利延伸创造了条件，在硬碎地层中钻进，提高回次进尺，提高小时效率，延长钻头寿命，体现出了液动锤技术的优越性，并对液动锤使用中易出现的问题进行了总结。

Abstract:

In the deep prospecting drilling construction of Xiaoqinling gold field, SYZX wire-line coring hydro-hammer was adopted to prevent deep drilling inclination, which can improve footage per run and efficiency per hour, and prolong service life of bit in hard brittle formation. The paper summed up the problems often encountered in the application of hydro-hammer.
