贵州毕节试验区饮用天然矿泉水资源勘查绿色钻探技术

Green drilling technology for exploration of drinking natural mineral water resources in Bijie experimental zone， Guizhou

摘要:

饮用天然矿泉水资源经济价值高、勘探成井工序流程复杂、技术质量标准严格，为防止勘探工作污染矿泉水水质，减轻对水源地生态环境的不利影响，需实施绿色勘查。本文以毕节试验区饮用天然矿泉水资源勘查项目为例，以探获优质矿泉水资源、保护当地生态环境、确保资源可持续开采为目的，根据工作区自然环境现状、地层结构特征以及技术质量要求，通过优选钻探设备、钻进工艺及清洁无污染成井材料、准确选定最优目标层、有害污染物质封堵、非目标含水层封隔等一系列绿色施工技术措施，较好地保护了区域环境，保证了矿泉水井成井质量和水质品质，其绿色施工技术对贵州省及全国的饮用天然矿泉水资源勘查开发具有良好的示范和借鉴作用。

Abstract:

Drinking natural mineral water resources have high economic value， the exploration and completion process is complex， and the technical and quality standards are strict.To prevent the exploration work from polluting the water quality of mineral water，reduce the adverse impact on the ecological environment of water sources， green exploration needs to be implemented.This article takes the exploration project of drinking natural mineral water resources in Bijie experimental zone as an example. In order to explore high-quality mineral water resources， protect the local ecological environment and ensure the sustainable development of resources.According to the current status of the natural environment in the operation area， the characteristics of the stratum structure and the technical quality requirements，Through a series of green construction technical measures such as optimization of drilling equipment， drilling technology， clean and pollut-free well-forming materials， accurate selection of the optimal target layer， blocking of harmful pollution substances， and isolation of non-target aquiferous layer， the regional environment is effectively protected and the quality and water quality of mineral water completion are ensured. The green construction technology has a good demonstration and reference role for the exploration and development of drinking natural mineral water resources in Guizhou Province and even the whole country.
