在钻孔造斜方面,我们使用了方向节钻具,取得了一定的效果.现简介如下.一方向节钻具的组成方向节钻具由钻杆、取粉管、万向节、异径接头、岩心管和钻头组成.如不用取粉管,短钻杆直接连在方向节上.二方向节结构方向节由上体、轴套、钢球、下体和轴杆组成(如图).上体上部有丝扣与钻杆锁接头相连,中有通水孔,下部丝扣与下体连

In the aspect of drilling diagonal, we use the direction of the section drill, and achieved some results are summarized as follows. A section of the direction of the section of the composition of the drill section Drill by the drill pipe, take the powder tube, universal joints, different diameter Joint, core pipe and drill bit. If not take the powder pipe, the short drill rod is directly connected with the direction knuckle. The two-way knuckle structure direction knuckle consists of upper body, sleeve, steel ball, lower body and shaft. The upper part of the body with threaded fasteners connected with the drill pipe joints, there are water holes, the lower thread and the lower body with even
