Technical Field

[0001] The utility model relates to the technical field of foaming agents, in particular to a foaming agent delivery device. Background Art

[0002] In the later stage of gas well exploitation, liquid accumulation in the wellbore is prone to occur, which affects the normal exploitation of the gas well. In the prior art, a solid foaming agent is added at the wellhead, and a large amount of low-density foam is continuously generated under the stirring action of the airflow after the accumulated liquid at the bottom of the well contacts the foaming agent. The foam will carry the accumulated liquid from the bottom of the well to the ground with the airflow, thereby achieving the purpose of clearing the accumulated liquid at the bottom of the well. When the foam needs to be collected, the prior art does not need to disassemble and replace the entire device, such as a foaming agent filling device recorded in the patent announcement number CN 217558304 U.
