在一般地层的钻孔内仍用玻璃管氢氟酸刻印测斜，以检验钻孔的弯曲度。以往每当钻孔需要测斜时都是将测斜工具专程送入孔内，待玻璃管刻印后，起钻取出工具。当孔深超过400米时，每起、下一次钻具至少需要1—2小时，而且消耗动力设备和人力。我们根据氢氟酸和水在容器中不断摇动不能刻印的特点，设计制做了两种不起钻测斜接头，一种供大口径合金和钢粒钻进使用；一种供小口径金刚石钻进使用。此种接头的功用是：当钻孔需测斜时，把接头接入钻具一起下到孔底，稍停，待玻璃管刻印后，不需起钻，便可以随即进行钻进，待打完一个回次再行
In general stratigraphic drilling is still glass with hydrofluoric acid marking inclinometer to test the curvature of the drilling. In the past, whenever the drilling needs to be measured obliquely, the inclinometer is sent into the hole in a special way. After the glass tube is inscribed, the drill is used to take out the tool. When the hole depth exceeds 400 meters, each time, the next drill at least 1-2 hours, and consume power equipment and manpower. We are based on hydrofluoric acid and water in the container constantly shaking can not be engraved features designed to make two can not afford to drill diagonal joints, one for large-diameter alloy and steel drilling use; for a small diameter diamond drill Into use. The function of this kind of joint is: when the drilling needs to be measured obliquely, connect the joint to the bottom of the hole together with the drilling tool, stop slightly. After the glass tube is inscribed, the drilling can be done immediately without drilling, Finish a second time
