| 摘 要： | 煤矿深处地下,地层结构复杂,由于地层结构过于复杂,在进行钻探工作时钻孔内很容易发生各类事故,这些事故对钻具的起拔影响很大,甚至导致钻具无法拔出,从而形成了起拔加压钻进问题。在以非平衡钻探工艺理论为基础,系统地研究研斯地质起拔钻探工艺,以求构建新的钻探工艺体系。

| Abstract: | Coal mine was underground, with complex formation structure, due to the complex stratigraphic structure, all kinds of borehole accidents easily happened when drilling work was doing, these accidents had a great influence on the pulling tool, and even led to drill can＇t pull out, thus formed the pulling pressure drilling problems. Based on the theory of unbalanced drilling technology, the systematic research of geological pulling drilling process was conducted to build a new drilling technology system. |
