Abstract

The invention discloses an efficient super-heavy oil demulsifier and a preparation method thereof. The efficient super-heavy oil demulsifier comprises, by weight, 14-19 parts of C10-16-alkyl alcohol ethoxylate propoxylate, 12-17 parts of tetraethylenepentamine polypropylene oxide polyoxyethylene ether, 7-13 parts of nonoxynol-10 phosphate, 5-10 parts of emulsifier OP-4, 6-12 parts of ethylene oxide-epoxy propane segmented copolymer, 4-8 parts of sorbeth hexalaurate, 3-6 parts of ammonium polyacryloyldimethyl taurate, 5-9 parts of sodium lauryl diphenyl ether disulfonate and 4-7 parts of N-propyl-perfluorooctane sulfonamide potassium glutamate. The raw materials such as C10-16-alkyl alcohol ethoxylate propoxylate, tetraethylenepentamine polypropylene oxide polyoxyethylene ether and ethylene oxide-epoxy propane segmented copolymer are added in the demulsifier, so that the demulsifier has the advantages of good demulsifying performance, high dehydration rate, low dehydration temperature and the like, and is wide in application range and promising market prospect.

Description

technical field [0001] The invention relates to a demulsifier and a preparation method thereof, in particular to a super heavy oil high-efficiency demulsifier and a preparation method thereof. Background technique [0002] As oilfields take measures to increase water injection and steam injection to increase fluid production in oil wells, the water content of oil well production fluids rises rapidly; at the same time, the extensive application of various oil production additives also makes crude oil, especially heavy oil and super heavy The composition of the produced fluid has become more complex, so that the efficient demulsification of heavy oil and super heavy oil has become a key technology that affects oil production cost, crude oil quality, production and control of oilfield environmental pollution. [0003] Demulsifier is a kind of surface active substance, which can destroy the structure of emulsified liquid, so as to achieve the purpose of separating the phases in ...
