摘要:

全面总结了中国地质调查局水文地质环境地质调查中心“十三五”期间在水工环钻探技术及装备、水合物防砂技术及干热岩钻探技术等方面取得的重要成果，主要包括：创新水工环勘查技术与装备助力地下水绿色勘查；提出防砂措施为水合物试验性开采提供技术支持；牵头实施青海共和盆地干热岩试验性勘查开发工程，突破高温硬岩钻探技术、装备、工艺等，力争建立世界一流干热岩示范性发电基地。同时，结合当前面临的形势与挑战，对“十四五”期间业务发展方向进行了展望。

Abstract:

This paper comprehensively summarizes the important achievements made by the Center for Hydrogeology and Environmental Geology Survey， CGS （CHEGS） on hydrogeological， engineering geological and environmental geological drilling technology and equipment， sand control technology for natural gas hydrate as well as hot dry rock drilling， etc. during the “13th Five-Year Plan” period. These achievements mainly include innovations in hydrogeological， engineering geological and environmental geological exploration technology and equipment which has helped green groundwater survey； proposal of sand control measures which has provided technical support for the experimental production of natural gas hydrate； organization and implementation of the experimental investigation and development project for hot dry rock in Gonghe Basin， Qinghai where significant breakthroughs have been made on drilling technology， equipment and process for the high temperature hard rock in order to establish a world-class demonstration power generation base. Moreover， with analysis of the existing challenges， this paper presents an outlook on the future research activities about drilling technology in the coming “14th Five-Year Plan” period.
