鋼粒鑽進對我們來說還是一項新的鑽進方法。雖然各地區在使用中摸索了一些經驗,提高了鑽進效率,但是,所收獲之效果却很不一致。有的提高了效率數倍,而有的却只20～30％,特別是在定時,定量等具體操作方法上還沒有摸清其規律。通過我們實際工作中的初步摸索、研究,得到了一些體會和心得。本着進一步研究商榷問題的精神,願把它介紹出來,供作大家研究參考和指正。
Steel grain drilling is still a new method of drilling for us. Although various regions have found some experience in their use and improved the drilling efficiency, the results obtained are very inconsistent. Some improve the efficiency of several times, while others only 20 ~ 30%, especially in the timing, quantitative and other specific methods of operation have not figure out the law. Through our initial work in the actual exploration, research, got some experience and experience. In the spirit of further studying the question, we’d like to introduce it for reference and correction.
