本文介绍了盐酸与二氧化碳联合洗井技术的原理及计算方法。经应用表明，该方法对第四系地层深井因过滤器堵塞洗井效果较好，可显著地增加机井出水量，从而为第四系地层机井增水节能提供了有效措施，同时可避免水井的重复建设，对地下水资源合理开发具有重要意义。
This paper introduces the principle and calculation method of combined washing technology of hydrochloric acid and carbon dioxide. The application shows that this method is effective for blockage of wells in quaternary deep reservoirs due to filter clogging, which can significantly increase the water output of the wells, thus providing effective measures for water and energy saving of Quaternary formation wells and avoiding the problems of wells Repeated construction is of great significance to the rational development of groundwater resources.
