摘要
近几十年来,岩心钻探一直是探矿行业中被采用的主要技术手段之一,特别是在深部探矿中被广泛应用,,但在进行钻进取心时冲洗液的选择及护壁防塌工作又是保证钻进顺利进行的重要工作之一。本文主要分析了岩心钻探经常遇到的有关冲洗液的问题,并进一步分析了在采用水泥注浆护壁防塌时的具体对策,希望能够给同行提供一些参考。
Core drilling has been one of the main technical means used in the exploration industry in recent decades,especially in deep exploration. However, the selection of flushing fluid and the work of protecting wall against collapse are important to ensure the smooth drilling. This paper mainly analyzes the problems of flushing fluid often encountered in core drilling, and further analyzes the concrete countermeasures when using cement grouting to protect the wall against collapse,hoping to provide some references for colleagues.
