| 中文摘要:天津东丽湖CGSD-01井为地热勘探井，设计井深4000 m，完钻井深4051.68 m。为最大程度清理钻井过程中对含水层的堵塞，本井采用了焦磷酸钠洗井、压缩空气洗井和酸化洗井3种工艺方法联合洗井，并先后进行2次抽水试验。联合抽水试验表明多工艺联合洗井效果理想。本文主要阐述了CGSD-01井洗井及抽水试验实施工艺，以期为今后同类研究及施工提供有益的借鉴。 |

| Abstract:The well CGSD-01 of Donglihu in Tianjin is a geothermal exploration well. The design depth of the well is 4000m and the completion depath is 4051.68m. In order to clean up the blockage of aquifer in the drilling process, the well is flushed by three methods, and pumping tests are carried out twice. This paper mainly describes the well washing and pumping test technology and process of the well CGSD-01, in order to provide useful reference for similar research in the future. |
