测量钻孔弯曲情况,一般的方法是提出钻具,下入专门的测斜仪进行测量.这样在操作中就比较麻烦,同时也需要时间.最近,鞍钢四○四勘探队在技术革新中,提出利用一种工具,在不提钻具的情况下,用氟氢酸测量钻孔弯曲的方法,获得成功.这种方法主要是利用一个工具,在工具上面装置一个铁管,铁管中放入玻璃管,于其中装入氟氢酸液,进行测量.这个工具的构造及安装情况如图1所示.它在钻具组成当中,起取粉管接手的作用,上部外丝扣连接取粉管,上部内丝扣连接钻杆,下部外丝扣连接岩心管.它是由外接手
Measuring the curvature of the borehole, the general method is to propose a drill tool, which is measured in a dedicated inclinometer, which is troublesome in operation and also takes time.Recently, Anshan Iron and Steel Co., Ltd. 2004 exploration team in technological innovation, It is proposed to use a tool to measure the bending of the drill hole with hydrofluoric acid without mention of the drilling tool, which is mainly to use a tool to install an iron pipe on the tool, Into the glass tube, which was filled with hydrofluoric acid solution, the measurement of the construction and installation of this tool shown in Figure 1. It is in the drill assembly, take the role of powder take over the handle, the upper part of the threaded connection Powder tube, the upper part of the inner threaded pipe connection drill pipe, the lower part of the outer threaded pipe connection core. It is by the external handle
