受控定向孔钻进用自动导航系统的分析研究

An automatic navigation system used for controlled directional drilling

钻探工程中常用受控定向孔钻进。在受控定向孔钻进中,及时了解并掌握钻孔顶角、方位角、造斜器安装角度和孔底实时位置(孔深)等参数非常重要。俄罗斯钻探工作者研发的定向钻进用信息、工艺、自动导航集身于一体的自动导航,对于提高定向钻进效率、保证钻孔质量、提高钻探技术经济指标具有重要意义,值得我们参考。

Controlled directional borehole drilling is often used in drilling engineering. In directional drilling,acquisition of borehole inclination and azimuth,installation angle of the deflecting tool,and hole bottom real time position(bore hole depth)are very important. Russian drillers have developed an automatic system integrating information,procedure and navigation used for directional drilling,which is of great significance for increasing drilling efficiency,guaranteeing borehole quality, and improving technical and economic indexes. It can provide some reference for Chinese counterparts.
