Study and the Application of Screw Drill Directional Drilling Technology in Wushan Copper Ore District

摘要:

结合在江西武山铜矿区ZKS1951孔的孔位上成功打出一个定向分支钻孔ZKS1952孔的施工过程，研究总结了复杂地层螺杆钻定向钻探大角度分支孔造斜的钻进工艺。主要介绍了螺杆钻定向钻探的原理、设备选型、钻进工艺及技术应用等。中靶精度、钻孔质量完全满足地质要求，取得了较好的地质效果和经济效益。创造了河南省有色地矿局复杂地层大角度螺杆钻定向钻探造斜的新纪录。

Abstract:

Combined with the construction process of successful completion of a directional branch hole ZKS1952 in ZKS1951 hole position of Jiangxi Wushan copper mine, this paper sums up the screw drill deflecting drilling process of directional drilling large angle branch hole in complex formation; mainly introduces the directional drilling principle, equipment selection, drilling technology and the application of screw drill. The target precision and drilling quality fully meet the geological requirements with good geological effects and economic benefits.
