景洪市嘎栋地热井特征及成井工艺总结分析

景洪盆地内蕴藏有丰富的地热资源。通过对景洪市嘎栋地热资源勘查地热井地质、施工情况及成果进行介绍,结合勘查施工实践,针对地热资源勘查开发、地热钻井施工、成井工艺及钻井过程中地质问题等有关内容进行经验总结并分析,对地热地质条件与地热井施工之间结合进行一些经验探讨,并对现行地热井规范中关于井身结构设计、取水层位确定、单井资源量计算等问题提出一定疑问。旨在通过实践及疑问探讨,力图找出为地热资源勘查开发提供值得借鉴的经验和教训。

The Features of Geothermal Well in Gadong of Jinghong City and the Well Completion Technology

There are abundant geothermal resources in Jinghong basin. Based on the geological conditions of geothermal well for geothermal resources exploration, construction conditions and the achievements, combined with the practice and experiences obtained in geothermal resources exploration, this paper summarizes and analyzes the geological issues related to geothermal resources exploration, geothermal well drilling, completion technology and well drilling; and discusses the relation between geological conditions and geothermal well construction. Some questions for the specifications in the current standard for geothermal well are raised, such as well body structure design, water level determination and calculation of single well resource, which is meant to find out valuable experience and lessons for geothermal resources exploration by practice and discussion.
