Another method is to pump chemical agent into the oil well through the plunger pump (the pump pressure is larger than the oil well pressure) through the ring control, which solves the problem of casing gas discharge, but the disadvantage of this method is that the power for driving the plunger pump is derived from the diesel generator set, and because of the possibility of natural gas leakage at the well site, the paraffin remover added by a single well is oil-based and flammable, so this method has serious potential safety hazard.
