Added water diluting electric wellhead dosing process

The invention relates to the technical field of oil field oil extraction, belongs to an added water diluting electric wellhead dosing process, and mainly solves the problems that in a conventional dosing process, during the dosing, the efficiency is low; the dosing on a well with high casing pressure is difficult; the dosing quantity is small; and the effective concentration of chemical agents in well fluid is difficult to ensure without added water dilution, and the like. The added water diluting electric wellhead dosing process adopts an injection system of a double-plunger pump 6; the wellhead added water is injected from a high-displacement end plunger of the double-plunger pump 6; the chemical agents are injected from a low-displacement end plunger; and the wellhead added water and the chemical agents are mixed at a mixer 7, and then, the mixture is injected into an oil well, so the mixed injection of the added water diluting injection chemical agents is realized. The added water diluting electric wellhead dosing process has the advantages that the dosing quantity and the water adding quantity are adjustable; the chemical agent concentration is uniform; the chemical agents can continuously and stably reach the well bottom; and the all-weather stable dosing requirement of the oil well under different well conditions can be met, and the like.
