Description

Full-automatic dosing device

Technical Field

The utility model relates to an oil gas field development technical field, concretely relates to full automatic reagent feeding device.

Background

With the gradual deepening of oil reservoir development and the continuous change of development forms, the wax deposition, scaling, corrosion of pipe rods, crude oil emulsification and the like under the oil well become main reasons influencing the normal production of the oil well and restricting the pump detection period. To control these factors, downhole dosing must be performed. The oil well is usually added with wax cleaner, wax inhibitor, bactericide, corrosion inhibitor, scale inhibitor, demulsifier, viscosity reducer, hydrogen sulfide inhibitor, beneficial microorganism nutrient and the like, and the produced fluids of different oil fields, different blocks and even different layers have different properties. The continuous dosing method is to maintain oil well production by using a dosing barrel to perform annular drip dosing of an oil well by means of liquid level difference. However, the dosing method is highly influenced by the liquid in the dosing barrel, has large flow rate difference and cannot realize constant flow. The medicine adding barrel is a plastic barrel, the strength is relatively low, in order to prevent foreign matters from falling into the barrel, the medicine adding barrel cover is screwed up, and the medicine adding barrel is easy to vacuumize and deform. Meanwhile, the medicine adding mode has small outlet pipe diameter, is easy to block and is inconvenient to maintain.

For this reason, patent specification with publication number CN208594906U discloses a normal pressure oil well wellhead chemical feeding device, which includes: the medicine feeding barrel, the breathing tube, the liquid inlet pipe, the main valve, the hose and the wellhead manifold; one end of the breathing tube is inserted into the medicine adding barrel from the top end of the medicine adding barrel to the lower part of the medicine adding barrel, and the other end of the breathing tube is positioned outside the medicine adding barrel; one end of the liquid inlet pipe is positioned in the dosing barrel, the other end of the liquid inlet pipe is connected with one end of the main valve, the other end of the main valve is connected with one end of the hose, and the other end of the hose is inserted into the wellhead manifold; the height of the breathing tube in the medicine adding barrel is higher than that of the liquid inlet tube in the medicine adding barrel. The normal pressure oil well wellhead chemical adding device has the disadvantages that firstly, because the pressure in the oil well is higher, the chemical adding is difficult to be carried out in a normal pressure adding mode; secondly, the phenomenon that the pipeline is easy to block still exists.
