Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical equipment, in particular to a material mixing device for a heavy oil viscosity reducer production line. Background Art
[0002] Viscosity reducers for heavy oil can significantly reduce the viscosity of heavy oil by reducing the oil-water interfacial tension, so that the heavy oil in the formation changes from an oil-in-water emulsion to an emulsion with water as the external phase, and are used to improve oil recovery. As a chemical agent added to drilling fluid, viscosity reducers for heavy oil can reduce the asphaltene and colloid content in heavy oil, improve pump efficiency and the dynamic liquid level of oil wells, reduce power consumption, reduce system pressure, and increase single well crude oil production. Common types of viscosity reducers include emulsified viscosity reducers, high-temperature viscosity reducers, and oil-soluble viscosity reducers.
[0003] Compound emulsified viscosity reducers are compounded by utilizing the synergistic effect between viscosity reducers of different structures to enhance their viscosity reducing performance and improve their adaptability to heavy oil in different regions. For example, compounding of anionic emulsifiers and nonionic emulsifiers can not only effectively reduce the surface tension of the oil-water interface, but also have high salt resistance. In a typical heavy oil viscosity reducer production process, surfactant octylphenol polyoxyethylene ether 12 (OP-12), sodium dodecylbenzene sulfonate (SDBS), sodium heavy alkylbenzene sulfonate (SAS) and fatty alcohol polyoxyethylene ether 15 (AEO-15) are mixed and reacted to obtain the compound. The above ingredients need to be fully mixed before the reaction to form a homogeneous phase to reduce the incidence of side reactions. At present, the uniformity of the material after treatment by ordinary mixing devices is still not ideal, especially there are obvious differences in components between the upper and bottom parts of the system. Summary of the invention
[0004] The technical problem to be solved by the utility model is that in the preparation process of producing a heavy oil viscosity reducer using OP-12, SDBS, SAS and AEO-15 as raw materials, the raw material mixing effect still needs to be improved.
