摘要
本文设计了一种简单的钻进方案及机具,经试验证实,可钻成曲率半径为3米左右拐角90°的弯曲孔,并对钻具造斜基本规律进行了研究。此项技术的完善将有希望用于对水平钻进距离要求不很长的特殊钻孔。
This paper presents the test research of curve hole drilling, designs a simple drilling plan and instrument and studies the basic law of oblique-making; the test proves that with this method curve holes in 90 angle can be drilled.
