西部地区战略性矿产靶区查证绿色钻探技术方法

The green drilling technology method for verification of strategic mineral target area in the western region

摘要:

针对西部典型地区复杂的地质条件和脆弱的生态环境特征，本文系统介绍了在西部地区战略性矿产靶区查证钻探施工中绿色钻探技术的创新应用与实践效果。通过采用轻便型钻机（MD-300、GK200、EP800等）降低环境扰动，创新性地实施双机联动施工模式提高作业效率，并因地制宜采用人工搬运、索道运输等生态友好型运输方式。在施工过程中，研发应用环保型冲洗液配方，建立循环利用系统，采用低固相冲洗液及场地防渗处理等关键技术措施。研究结果表明，该技术体系可显著降低钻探活动对土壤和水体的污染，同时通过复草复耕、草皮预留、戈壁生态恢复等生态修复技术，实现了钻探区域生态环境的有效恢复。该研究成果为西部典型地区资源开发与环境保护协调发展提供了可靠的技术支撑。

Abstract:

In view of the complex geological conditions and fragile ecological environment characteristics in typical areas of western China， this paper systematically introduces the innovative application and practical effect of green drilling technology. Through the use of portable drilling rigs （MD-300， GK200， EP800， etc.） to reduce environmental disturbances， innovative implementation of dual-machine linkage construction mode to improve operational efficiency， and according to local conditions， ecologically friendly transportation methods such as manual handling and cableway transportation are adopted. In the construction process， the key technical measures such as the development and application of environmentally friendly flushing fluid formula， the establishment of recycling system， the use of low solid flushing fluid and site anti-seepage treatment are adopted. The results show that the technical system can significantly reduce the pollution of soil and water caused by drilling activities. At the same time， through ecological restoration technologies such as re-grassing and re-tillage， turf reservation and gobi ecological restoration， the effective restoration of the ecological environment in the drilling area is realized. The research results provide reliable technical support for the coordinated development of resource development and environmental protection in typical western regions.
