深孔绳索取心液动锤钻具研制及应用

Development and Application of Wire-line Coring Hydro-hammer for Deep Hole

摘要:

绳索取心液动锤钻探技术具有钻进效率高，可大幅度增加回次进尺、延长钻头寿命、减少辅助工作时间等优势被广泛应用。本文主要针对深孔环境对钻具整体强度、安全性、稳定性、工作寿命、高背压适应性等的具体要求，对原SYZX钻具所做的一系列改进和完善进行了论述。生产试验证明，改进后的钻具完全满足深孔钻探施工对钻具的更高要求。

Abstract:

The wire-line coring hydro-hammer drilling technology is widely applied for its advantages of effective drilling, largely increased round footage, prolonged bit service life, less auxiliary time and so on. Aiming at the specific requirements of the deep hole environment for the drilling tools in overall strength, safety, stability, service life, high backpressure adaptability and other aspects, this paper discusses a series of improvement and perfection of the original SYZX drilling tools. The production test proves that the improved drilling tools can fully meet the higher requirements for deep drilling construction.
