| 摘 要： | 目前,深部煤田勘探越来越广泛,取芯技术也越来越成熟,但是,在钻探过程中,难免会出现因为操作技术、地层原因以及孔内事故等问题造成目的煤层的打丢和打薄,此时,补取煤芯显得尤为重要。本文系统介绍了导斜器在深井勘探中补取煤芯的应用,为煤层补芯提供了一种简便易行的操作方法,具有一定的推广价值。

| Abstract: | At present,the deep coal exploration is more and more abroad and the core drilling technology is more and more mature,but in the course of drilling,it is unavoidable that the coal measures is drilled lost or deficient for operate technology,stratum reason,down-hole trouble and so on.This time,additional core is very important.This paper introduced the application of deflecting tool in deep coal exploration,a simple method is provided for additional core and it has some promotional value. |
