The chemical feeding pipe 3 is connected to an external supply vehicle, and the liquid outlet pipe 6 is connected to a gas well.
Further, a flow meter 5 and a valve 7 are installed on the liquid outlet pipe 6.
It should be noted that, the flow meter 5 may monitor the flow rate passing through the liquid outlet pipe 6, and the valve 7 may be opened or closed automatically to control the working state of the liquid outlet pipe 6.
Further, a wireless transmission device 10 is further arranged on the equipment shell 2, and the wireless transmission device 10 is electrically connected with the plunger pump 8 and the liquid level meter 9 respectively.

The cost reduction and synergy effects are remarkable, and the production of a gas well is effectively ensured.

Because the dynamic connection with the production of the gas well cannot be realized, the daily reagent injection amount is a fixed value, and in order to prevent the risk of unstable gas well yield caused by the too small reagent dosage, the reagent dosage is often too large, and the reagent dosage in the state is not in real time and directly connected with the production state of the gas well, and can not be changed along with the production dynamic state. The dosage of the medicament in the intelligent filling stage is analyzed in real time according to the production dynamics of the gas well, the dosage of the medicament can be accurately designed, manual participation is not needed, and the dosage of the medicament in the intelligent filling stage is less, and the yield is stable and increased.
