摘要：

为解决中粗粒花岗岩地层中反井法施工大倾角斜井时偏斜精度低的技术难题，采用高精度斜导孔轨迹控制技术、定向钻具组合技术以及钻孔孔壁泥浆保护技术，研制出新型TDX-1500斜导孔专用钻机，研发出一套大倾角反井法斜导孔的快速、高效、精确地钻孔定向控制技术。以河北丰宁抽水蓄能电站1#引水系统高压管道下斜段为工业性试验工程，使用TDX-1500斜导孔专用钻机、新型7LZ120短螺杆钻具以及SMWD-76无线随钻测斜仪等新型钻孔施工设备，利用钻孔泥浆进行护壁钻进，施工一条斜长302 m、倾角53°、偏斜率为0.42%的导孔，钻孔实际轨迹与设计轨迹高度拟合，斜导孔轨迹平缓圆滑，并精确进入靶域，技术参数上完全满足反井法施工的技术要求。

Abstract:

The deflection accuracy of inclined shaft in intermediate coarse granite construction by raiseboring method is low. Hence, a new type of TDX1500 special drilling machine for oblique guide hole is developed by trajectorycontrol technology with highprecision, drilling machine combination and slurry protection technology for oblique guide hole; and a set of rapid, highefficient and accurate directional control technology for borehole of oblique guide hole with large dig angle constructed by raiseboring method is developed as well. The TDX1500 special drilling machine for oblique guide hole, newtype of 7LZ120 short screw drilling tool and SMWD76 wireless inclinometer are used in oblique section of #1 highpressure water diversion pipe of Fengning Pumpedstorage Hydropower Station; the shaft wall is protected by slurry; and a 302 mlong guide hole with dig angle of 53° and deflection of 0.42% is constructed; and the drilling real trajectory is highly fitted with the design trajectory, and the trajectory of oblique guide hole presents smoothly within the target area, and the technical parameters can fully meet the requirement of raiseboring construction.

Key words: pumpedstorage hydropower station, raiseboring method, inclined shaft with large dip angle, oblique guide hole, directional drilling
