Problems solved by technology

[0003] There are relatively few reports on oil-soluble heavy oil viscosity reducers at home and abroad. Chinese patent application 200810047022.8 discloses a preparation method for oil-soluble heavy oil viscosity reducers used in heavy oil pipeline transportation. The viscosity reducer obtained by this method is The composition of the agent is relatively single, and the polarity of the groups contained in the components is relatively weak, so the effect of improving the low temperature fluidity of heavy oil is limited

Abstract

The invention belongs to the field of a thick oil viscosity reducer, aiming at providing an oil-soluble thick oil viscosity reducer which comprises a primary mixture, a cationic surfactant, a light oil, polyoxyethylene nonyl phenyl ether, isopropanol and a catalyst; compared with the prior art, the invention has the advantages that: the maximum viscosity reduction rate can run up to 99% at most, which meets the demand of flowable viscosity of the thick oil in a duct, significantly ameliorates the low-temperature flowability of the thick oil and brings great viscosity reduction effect; in addition to the introduction of benzene sulfonic acid groups and hydroxyl groups with stronger polarity into the components, the cationic surfactant groups are also introduced; the introduction of the cationic surfactant more efficiently strengthens mutual repulsion between wax crystal particles and between asphaltine particles and improves the dispersity and deposition resistance thereof, thus improving the low-temperature flowability of the thick oil; the invention has wide sources of the raw materials, inexpensive cost, more simple synthesis process and no need of protecting gases in the production process; the method is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the field of heavy oil viscosity reducer, and particularly relates to an oil-soluble heavy oil viscosity reducer and a preparation method thereof. The viscosity reducer comprises a primary mixture, a cationic surfactant, light oil, and nonylphenol polyoxyethylene ether , isopropanol, catalyst. Background technique [0002] With the deepening of heavy oil mining, the high viscosity and high content of colloidal asphaltenes of heavy oil have brought great difficulties to its storage and transportation. Therefore, the rationality, advancement and economy of heavy oil transportation technology directly affect the comprehensive technical indicators of crude oil production. For a long time, three methods have been adopted for high-condensation and high-viscosity crude oil at home and abroad: traditional heating, viscosity-reducing transportation, emulsification and viscosity-reducing transportation, and blending and thinning for vis...
