摘要：

A composition comprising a hydrocarbon solvent and the additive has been developed to remove asphaltene-resin-paraffin deposits (ARPD). As an additive, it contains a block of copolymer ethylene oxide and propylene oxide based on glycerine - Laprol with a molecular weight of 3600-600. The efficacy of the compounds is identified on ARPD samples from various fields ("Absheroneft" OGPU, large-sized oil-field "Muradkhanli", OGPU named after N. Narimanov and PU "Zhetybaymunaygaz"). The effectiveness of various fields ARPD removal using obtained compositions is very high. Depressor properties of the compositions were determined based on kinematic viscosity and pour point. It has been established that the presence of the prepared compounds in oil reduces the viscosity and pour point of oil produced at "Absheroneft" OGPU, OGPU named after N. Narimanov, and also there is a modification of the oil rheology at "Uzen" field from pseudoplastic flow to newtonian flow. (C) 2016 "OilGasScientificResearch Project"' Institute.
