- 介绍了应用气举反循环钻进工艺解决这些疑难技术问题的成功案例。
The paper introduces the typical examples for resolving these problems by air-lift reverse circulation drilling technology. - 运用气举反循环钻进,在满足一定条件下适当增加双壁钻具长度即可得到较大钻进孔深。
Apply air reverse circulation drilling, appropriate increase length of twofold wall drill tools under certain conditions, may be drilling much deeper. - 并提出必须重视和加强对该结构双壁钻杆的研制工作,为复合空气反循环钻进新方法的推广打下良好的基础。
The development of double barreled drilling rod of said structure will lay a good foundation for thepopulization of the composite air counter circulation method.
