Description

Technical Field

[0001] The utility model relates to the technical field of oilfield chemical dosing, in particular to an oilfield automatic chemical dosing device which is convenient to operate. Background Technique

[0002] Oilfield chemical dosing is an important measure in the process of oil production. One of the main purposes of well chemical dosing is to prevent wax deposition. Wax deposition will seriously affect the normal production of oil wells and reduce the oil production efficiency. By dosing chemicals, the viscosity of crude oil can be effectively reduced, the wax deposition rate can be slowed down, so as to extend the maintenance-free period of oil wells and improve the oil production efficiency. The oilfield chemical dosing device can improve the quality of crude oil, and improve the purity and stability of crude oil by injecting various chemical agents such as cleaning agents, preservatives, bactericides, etc. into the oil wells.
