聊古1井在不同取水模式下气体观测效果的对比分析

Contrastive analysis of gas observation effect under different water in taking patterns in Liaogu-1 well

摘要:

为解决聊古1井断流问题,聊城地震水化试验站先后引进、开发了人工激发引流观测技术和潜水泵变频稳流抽水技术。对天然自流观测系统、人工激发引流观测系统和潜水泵变频稳流抽水观测系统等3种不同取水模式下产出的气体观测数据进行一致性分析。结果表明,人工激发引流观测系统下气体观测动态特征年变比较明显,潜水泵变频稳流抽水观测系统下气体观测动态特征与天然自流状态下的动态特征基本一致。

Abstract:

To solve the problem of drying-up，the artificial excitation drainage observation and frequency conversion with steady flow pumping by submersible pump have been developed in the Liaogu-1 well． This paper analyzes the gas observation data from three kinds of water in taking patterns，including self-flow，artificial excitation drainage and frequency conversion with steady flow pumping by submersible pump． The results reveal that the gas observation dynamic characteristics by frequency conversion with steady flow pumping by submersible pump is basically consistent with by self-flow． But compared with self-flow，there were visible changes by artificial excitation drainage．
