阳山矿区严重漏失垮塌地层钻进工艺及工程实践
Drilling technology and engineering practice for seriously lost and collapsed formation in Yangshan Mining Area
摘要
Abstract
The research and application of rapid drilling techniques for drilling through severely permeable and collapsed formations is one of the urgent issues to be addressed in solid mineral exploration geological core drilling.Combined with the practice of drilling engineering in Yangshan gold mine in Gansu Province,in view of the serious leakage and collapse of the long hole section,this article summarizes a set of drilling techniques suitable for rapid exploration in this mining area,which includes wire-line core drilling and full-hole drilling blind drilling technology used to quickly passing through the formation,and cement temporary plugging,casing plugging,reaming,following pipe used to plug the formation,and analysis their application effects.At last,the understanding and thinking of drilling in the formation were proposed.This article is intended to provide a reference for drilling in similar formation.关键词
