Embodiment Construction

[0018] The present invention will be further explained below in conjunction with the drawings:

[0019] Such as figure 1 As shown, this polymer flooding crude oil cold transport fluidization device is composed of a stator shell and a spoiler rotor 3. The stator shell is a shell, and the spoiler rotor 3 is an impeller composed of multiple sets of blades. image 3 with Figure 4 , The blade 10 is arranged with a certain aperture and number of holes 11, the angle between the adjacent two sets of blades 10 is 60°, so that it can ensure the shearing while leaving enough circulation area, which can effectively reduce the local resistance of the device . The central shaft 5 at both ends of the spoiler rotor 3 is rotatably connected with the stator housing through sliding bearings 6. The spoiler rotor 3 can rotate freely in the stator housing. There are oil inlet pipes 7 and oil outlet pipes 8 on the stator housing. Crude oil enters the condenser through the oil inlet pipe 8. After driv...

Abstract

The invention relates to a polymer-flooding crude oil low-temperature conveying fluidization device. The polymer-flooding crude oil low-temperature conveying fluidization device comprises a stator housing and a disturbed flow rotor, wherein the disturbed flow rotor is composed of a plurality of sets of blades, holes are formed in each blade, the portions, arranged at the two ends of the disturbed flow rotor, of a center shaft are connected with the stator housing in a rotary mode through sliding bearings, and an oil inlet pipe and an outlet pipe are arranged on the stator housing. According to the polymer-flooding crude oil low-temperature conveying fluidization device, crude oil, with the temperature lower than the solidifying point, of oil well output liquid is sheared to be granular, low-temperature conveying can be achieved, when the temperature of wellhead output liquid is higher than the solidifying point, only normal gathering and conveying are needed, and rise of the wellhead return pressure can be effectively controlled under the two working conditions.

Description

[0001] 1. Technical field: [0002] The invention relates to equipment for processing the produced liquid of a polymer flooding cold transport well to become a particle suspension flow, in particular to a fluidization device for cold transport of polymer flooding crude oil. 2. Background technology: [0003] Most of my country's crude oil has the characteristics of high wax content, high freezing point and high viscosity, that is, "three highs". Compared with foreign oilfields, the oil and gas gathering and transportation process has high energy consumption, high emissions, and low efficiency, and the cost of oil and gas gathering and transportation accounts for more than 30% of the total production cost of oilfields. Due to the particularity of oil and gas reservoirs and the own characteristics of the development model, we are required not to copy foreign advanced technologies. How to develop new oil and gas gathering and transportation processes is a key technical problem ...
