四川理塘金矿勘探复杂地层钻探施工难点及其对策
Difficulties and countermeasures of drilling construction in complex strata in Litang Gold Mine, Sichuan
【摘要】 四川省理塘金矿区的地层含有多层、超厚强水敏性缩径地层,伴随着破碎掉块和漏失情况的发生,施工难度很大。通过施工工艺和冲洗液等多方面的研究和探讨,通过实施应用和项目施工人员的协同配合,成功地解决了强水敏性复杂地层钻进的技术难题。并取得了较好的使用效果和经济效益。
【Abstract】 The formation of Litang gold mining area in Sichuan Province contains multi-layer, super-thick and strong water-sensitive reducing strata. Through the study and discussion of construction technology and flushing fluid, the technical problems of drilling in complex formation with strong water sensitivity are successfully solved through application and cooperation of project construction personnel. And has obtained the good use effect and the economic benefit.
