FIELD: oil production, particularly methods or apparatus for cleaning boreholes or wells using chemical means for preventing or limiting the deposition of paraffins or like substances.
SUBSTANCE: method involves injecting fluid flow in oil production well communicated with oil field; displacing oil and producing effluent fluid comprising oil, wherein at least two flows are injected in at least two production zones of oil well or in at least two different producing wells and two effluent fluid flows are mixed before producing thereof; adding two different scaling inhibitors in oil field or fields and/or in fluids for two zones or wells, wherein the scaling inhibitors comprise different components, which may be analytically defined.
EFFECT: increased quality of scale inhibition due to inhibition process control.
