Special quantitative dosing and diluting device for oil field

Abstract

The invention discloses a special quantitative dosing and diluting device for an oil field. The device comprises a dosing barrel, and supporting plates are fixedly connected to the outer walls of the two sides of the dosing barrel; the upper side wall of each supporting plate is fixedly connected with a support, and the ends, away from the supporting plates, of the two supports are jointly and fixedly connected with a motor. The tail end of an output shaft of the motor is fixedly connected with a cam; an adding mechanism is arranged on the upper side wall of each supporting plate; the adding mechanism comprises a side plate fixedly connected to the upper side wall of the supporting plate. The outer wall of the side plate is jointly and fixedly connected with an adding box through two supporting rods, and a medicine inlet is formed in the upper side wall of the adding box. According to the invention, water and a corrosion inhibitor in the two adding boxes intermittently flow into the dosing barrel to complete quantitative dilution of the corrosion inhibitor and the water, the situation that the concentration of the corrosion inhibitor is high and low in the manual dilution process is avoided, and meanwhile, the dilution speed of the corrosion inhibitor and the water can be increased through the arrangement of the dilution rod and the dilution blades.

Description

technical field [0001] The invention relates to the technical field of oilfields, in particular to a quantitative dosing and dilution device for oilfields. Background technique [0002] In recent years, my country's oilfield chemical technology has developed rapidly, forming a relatively broad oilfield chemical market. Deep well pumps are widely used in oilfields for oil recovery. Because the produced crude oil contains high colloids and asphaltenes, it is commonly called wax in oilfields. In the process of crude oil extraction, the rods, pipes, and pumps of the oil well are often waxed, which increases the load of the pumping unit, and seriously causes the deep well pump to fail to work normally. Therefore, it is necessary to add a corrosion inhibitor to the oil field to remove a small amount of colloid and asphaltene from the rods, pipes, and pumps in the oil well, thereby reducing the load on the pumping well. [0003] At present, it is necessary to dilute the corrosion i...

AI Technical Summary

Problems solved by technology

[0003] At present, it is necessary to dilute the corrosion inhibitor before adding it to the oil field, and the traditional dilution method is mostly manual dilution, which is labor-intensive, and it is impossible to quantitatively dilute the buffer and water during the dilution process of the corrosion inhibitor. The dilution effect is not very good
