| 摘 要： | 我国地热田区多利用自流热水井开展地震地下流体物理化学多测项综合观测,但是随着各地地热资源的开发,很多观测井已经断流或即将断流,这使地下流体观测项目大幅减少,甚至全部停测,蒙受很大损失.针对这种情况,山东聊城聊古1井先后引进与开发了人工激发自流观测技术与潜水泵变频稳流抽水观测技术,实现了原有热水自流井的稳定出水,保持原有地下水化学观测项目,并新增井水位与井水温度观测,确保该井地震监测能力.这种技术的开发,性价比很高,且大大延长了观测井的观测寿命,是值得推广与应用的新技术.

| Abstract: | In China most synthetical observations of underground fluid are carried on by making use of self-flow hot water well in geothermal fields. However, due to more and more extraction of geothermal resources, a number of observation wells have dried-up or are drying-up, substantially reducing observation items, even obliging observation stopped with large lossing. In the face of such condition, the artifical self flow observation and frequency conversion of submersible pump have been brought in and developed in Liaogu 1 well. Hence, stably flowing of hot water self-flow well has been carried out, primary observation terms have been kept on and water level and temperature observation are newly performed, and the capability of earthquake monitoring of the Liaogu-1 well are guarenteed. The develepment of this technology has a reasonable ratio of performance over price, and it can delay the life of observation well. This technology is worth popularizing and application.Key words: observation of pumping flow; observation of self-flow; frequency conversion of submersible pump; artificial excitation;dry-up of well; Liaogu-1 well |
