FIELD: petroleum industry. SUBSTANCE: invention relates to method of decrease of corrosion activity of acid-containing corrosive oil raw by addition of naphthenates of metals of the group IIA to the parent oil raw in effective amount or the second raw in effective amount containing naphthenates of metals of the group IA and IIA. The parent oil raw has effective amount of water from 0.3 to 7 wt.% of total content of oil raw. EFFECT: decreased corrosion activity of oil raw producing, decreased corrosion of equipment used for extraction, transport and processing crude oil raw. 27 cl, 3 dwg, 24 ex |
