Based on the theory study, a directional drilling guidance system is developed for practical require, its working flow as follows: before construction, design the best track practically, and save in the system. During drilling, the system measures well oblique angle and azimuth to watch well track. Drill driver compares designing well track with measuring track showing on display unit, controls joy stick experientially, adjusts drill direction, finally realizes directional drill.

在理论研究的基础上，结合实际需要，研究设计了一种定向钻井导航系统，使用该系统进行定向穿越施工的工作过程如下：在施工前，根据实际情况，先设计一条最佳穿越路线，存入系统；在钻进中，系统通过对井轨的井斜、方位等参数的测量，对其进行实时监测；地面的司钻手通过对显示仪所显示的实际井轨参数及设计井轨参数进行比较，根据经验操纵操作杆，调整钻机前进方向，以达到对钻进过程的控制，最终实现定向钻井。

In fishing,the sliding cone blocks enter the fish cavity easily acted by a guide shoe and a guide cone,slide downward by its own weight,produce relative displacement to the guide rail slope,and the radial distance between its tooth face and the spear rod increases until it touches the inner wall of the fish cavity; while lifting the drilling string,the guide rail slope on the spear rod forces the sliding cone blocks to bite the inner wall of the tubing fished.

打捞时在引鞋和导锥的作用下滑牙块能够顺利进入鱼腔并依靠自重下滑，沿导轨外伸直至其齿面与鱼腔内壁接触；随后上提钻柱，矛杆上的导轨斜面迫使滑牙块咬紧被打捞油管内壁，当油管严重偏磨使一对滑牙块卡在磨穿位置时，另一对能有效卡在未磨损部位，同时外筒限制了油管外胀变形。
