SET OF SALT DEPOSIT INHIBITORS HAVING GOOF PROFILES OF ABSORPTION AND THEIR USE IN OIL PRODUCTION

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention relates to set of the salt deposit inhibitors and their use to intensify the flow from the oil field. Method of salt deposits inhibiting in oil field includes the stages: a) injection of at least two inlet fluid flows to at least two production zones of the oil production well connected with oil field, or to at least two different oil production wells, from which at least two outlet flows from two zones or wells are combined prior to extraction with the salt deposits inhibitor, containing detected groups and injected to the oil field(s) and/or fluid; at that two different salt deposit inhibitors are used, each of them is intended for each of two zones or wells; these inhibitors contain different detected groups as per their maximum absorption, that are identified by the analytical method for absorption; b) oil displacement, c) extraction of the output fluid flow containing oil, d) measurement of quantities of different inhibitors in the extracted fluid flow by the analytical method for absorption or of the fluid obtained from it, and e) optionally decision of the problem relating with salt deposits creation in the zone or in the well, for which the salt deposits inhibitor is intended, if quantity of the inhibitor is below the specified value, where one of two inhibitors is specified polymer, and another inhibitor is the another specified polymer. Invention is developed in subclaims.;EFFECT: increased inhibiting efficiency.;7 cl, 6 tbl, 10 ex
