金刚石冲击回转钻进是我国机械岩心钻探工程的重大技术改革，特别是SC射流式冲击器在钻探技术中的应用，解决了目前冲击器存在的许多问题，它是结合我国钻探技术的实际情况而研制的。几年来，在长春地院的帮助下，我队在两个矿区试验了10个钻孔，累计进尺2116.78m，收到了一定的成效。使用结果表明：SC-54型冲击器工作稳定，适应性较强，可调换射流元件来适应深、浅孔作业。特别是在坚硬、破碎地层钻进明显优于普通回转钻进。
Diamond impact rotary drilling is a major technical innovation of China’s mechanical core drilling project, especially the application of SC jet impactor in drilling technology, which solves many problems existing in the present impactor. It combines the actual situation of drilling technology in our country Developed. In the past few years, with the help of the Changchun Institute, our team experimented with 10 holes in two mines, accumulating a total footage of 2116.78m and received some success. The results show that: SC-54 impactor work stable, strong adaptability, jet components can be changed to adapt to the deep, shallow hole operations. Especially in hard, broken ground drilling significantly better than ordinary rotary drilling.
