高能射流式液动锤在赵固一矿井下穿层注浆钻孔中的应用
|
摘要
井下定向钻进是实现煤矿瓦斯高效抽采和防治底板突水的重要途径,多采用回转钻进的方法,钻遇硬岩地层时,钻进效率低、钻孔周期长、成本高,严重影响了井下瓦斯抽放钻孔等的工程进度及成孔质量。赵固一矿井下灰岩地层钻进试验结果表明,使用SC86H型高能射流式液动锤实施冲击回转钻进,通过合理控制泵压、转速和钻压,钻进效率较常规PDC钻头回转钻进提高了3倍,节约了钻进成本。
Directional drilling under coal mine is an important technology to realize efficient gas extraction and prevent flood water inrush.The method of rotary drilling is mostly adopts.In hard rocks,low drilling efficiency,long drilling cycle and high construction cost seriously affect the project progress and quality of gas extraction drilling.The drilling test results of the limestone strata of Zhaogu mine-1 show that with reasonable control of pump pressure,rotary speed and weight on bit,the efficiency of impact rotary drilling by SC86 H high energy liquid-jet hydraulic hammer is increased by 3 times than that of conventional PDC rotary drilling,and the drilling cost is saved.
