地质岩心钻探施工中吸附卡钻事故处理分析

Analysis of Adsorption Sticking Accident in Geological Core Drilling Construction

地质岩心钻探施工中吸附卡钻事故经常发生,在卡钻事故发生之后,一旦处理不当,就会导致部分钻孔被迫提前终孔,无法达到理想的地质岩心钻探施工目标。因此,本文以某地质岩心钻探施工项目ZK2562号孔为例,对该孔发生吸附卡钻事故的起因及处理方案进行了简单的分析。

Absorption sticking accidents often occur in geological core drilling construction.After sticking accidents occur,once improperly handled,some drilling holes will be forced to finish ahead of time,which can not reach the ideal geological core drilling construction target.Therefore,taking hole ZK2562,a geological core drilling project,as an example,this paper makes a simple analysis of the causes and treatment schemes of the adsorptive Sticking Accident in the hole.
