| 摘 要： | 简要介绍了聊古1井井区的水文地质条件,全面调查了聊城地震水化站外围地热资源开发的现状,在此基础上分析了地热开发对地震地下流体观测及其动态的影响。结果表明,井区周围地热开发导致聊古1井断流,引起了各项动态异常的出现;该井区碳酸盐岩岩溶性水的开采对地下流体观测及其动态产生影响,特别是冬季供暖期的开采对地下水物理动态产生严重干扰。为了消除或减弱这种影响,通过改造井口装置实现人工自流的方法,保证了各项观测,而且部分测项的观测条件得到改善,多数测项的动态资料可连续,只有少数测项动态受到较大影响,井口改造取得了一定实效。然而,根本的出路还应是保护观测系统,停止同层地热开发

| Abstract: | In this paper,hydrogeological condition of Liaogu-1 well was introduced; the present condition of extraction of geothermal resources around Liaocheng seism-hydrochemistry station was researched comprehensively. The effect of the extraction of geothermal resources on underground fluid observation and behaviors were analyzed basing on the research. It is believed that the extraction of geothermal resources in the well area resulted in the dry-up of Liaogu-1 well and the emergence of abnormal behaviors in vari |
