| 摘 要： | 硬而破碎地层取芯是石油钻井的一个难题。采用再制多棱人造金刚石烧结体试命的取芯钻头,用于花岗片麻岩地层取得了较好的使用效果。ABSTRACT Coring into hard and friable strata has been difficu-lties during petrolleum drilling. In this paper,a specially shaped multi-lobed PCD block is developed for making core bit, such bit has obtai-ned advantageous effect when used in drilling granite schist strata. |
