Problems solved by technology

This invention uses a viscosity reducer to replace part of the thin oil through a simple process modification, which greatly reduces the production cost of super heavy oil, but this invention cannot control the input amount of the viscosity reducer according to the viscosity of the oil, and cannot achieve a higher viscosity. Large oil return to remix with emulsifier or viscosity reducer

Abstract

The invention relates to the technical field of crude oil viscosity reduction treatment, in particular to emulsification treatment equipment for medium viscous crude oil viscosity reduction. The emulsification treatment equipment comprises a stirring sleeve, an oil sealing sleeve, a viscosity reducer conveying pipe, an internal rotation assembly, a spring and a fixing device. The oil sealing sleeve is slidably connected into the stirring sleeve and fixedly connected to the viscosity reducer conveying pipe, and the lower end of the internal rotation assembly is rotationally connected to the oilsealing sleeve. The middle end of the internal rotation assembly is fixedly connected to the stirring sleeve, and the internal rotation assembly is slidably connected to the viscosity reducer conveying pipe. The fixing device is fixedly connected to the upper end of the viscosity reducer conveying pipe, and the spring is arranged between the internal rotation assembly and the fixing device. The emulsification treatment equipment can rotate during oil liquid flowing, and oil liquid is mixed with an emulsifier or an viscosity reducer advantageously; and the conveying flow rate of the emulsifieror the viscosity reducer can be increased when the viscosity of the oil liquid is large, the backflow proportion of the oil liquid is increased, the inclination angle of inner stirring blades can bedecreased, and flowing resistance of the oil liquid is reduced.

Description

technical field [0001] The invention relates to the technical field of crude oil viscosity reduction treatment, in particular to emulsification treatment equipment for viscous crude oil viscosity reduction. Background technique [0002] For example, the patent application number is CN201210537149.4, a method and equipment suitable for super heavy oil recovery. The method includes injecting a mixture of thin oil and viscosity reducer into the bottom of the oil well, mixing it with heavy oil, and then extracting the oil. operate. Its equipment includes intersecting thin oil pipelines (3) and viscosity reducer pipelines connected with drug storage tanks (1) and metering pumps (2), and the intersected pipelines are sequentially connected to ground mixers (5) and oil well casings ( 6) The annular space. This invention uses a viscosity reducer to replace part of the thin oil through a simple process modification, which greatly reduces the production cost of super heavy oil, but ...
