Problems solved by technology

Heating to reduce viscosity requires the addition of intermediate heating stations, heat energy loss, and increased costs. For dilution and transportation, there is a problem that the source of diluted oil in heavy oil production areas is very limited, and at the same time it causes depreciation of light oil. In addition, the mixing of different qualities of crude oil may cause Adversely affect the refining and processing of crude oil

Embodiment 1

[0047] In parts by weight, take 150 parts of normal temperature water and add 0.5 part of water-soluble starch, stir to make it fully mixed, slowly heat to 60 ° C, then add 0.25 part of Tween 80, 0.25 part of Span 80 and 0.25 part of Twelve Sodium alkyl benzene sulfonate, stir to make it fully mixed to obtain emulsified viscosity reducer; take 350 parts of heavy viscous oil, add 10 parts of bio-based heavy oil, and mechanically stir at 100 ° C to fully mix to obtain oil phase material. The oil phase material and the emulsified viscosity reducer were added to the colloid mill for emulsification treatment to obtain an emulsified heavy oil. The properties of the emulsified heavy oil are shown in Table 1.

Abstract

The invention provides a thick oil emulsification viscosity reducer, emulsified thick oil and a preparation method of the emulsified thick oil, and the emulsified viscosity reducer comprises the following components in parts by weight: 0.1-10 parts of a nonionic surfactant; 0.1 to 10 parts of an anionic surfactant; 0.01 to 5 parts of an auxiliary agent; and 100 to 5000 parts of water. The emulsified heavy oil comprises the emulsified viscosity reducer, thickened oil and bio-base oil. Compared with the existing emulsifying viscosity reducer, the emulsifying viscosity reducer provided by the invention has the advantage that the stability of an emulsion system is greatly improved on the premise that the emulsifying viscosity reduction effect is good.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and particularly relates to a heavy oil emulsified viscosity reducer, an emulsified heavy oil and a preparation method thereof. Background technique [0002] At present, the reserves of light oil are decreasing day by day, and the proportion of heavy oil exploitation is gradually increasing. In heavy oil, the content of macromolecular hydrocarbon molecules such as colloid and asphaltene is usually large, which shows the characteristics of high density, high viscosity and difficult flow. In addition, compared with conventional crude oil, heavy oil has obvious price in the crude oil market. The advantages of purchasing low-cost heavy oil are of great significance to the improvement of refinery quality and efficiency. How to solve the transportation problem of heavy oil is the key to the processing of heavy oil, especially the purchase of heavy oil from overseas. At present, the world's prove...
