Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described:

[0018] Such as figure 1 As shown, this crude oil cold transport fluidization device for polymer flooding is composed of a stator casing and a spoiler rotor 3. The stator casing is a shell, and the spoiler rotor 3 is an impeller composed of multiple sets of blades. Refer to image 3 and Figure 4 , the blades 10 are arranged with holes 11 with a certain aperture and number, and the included angle between two adjacent groups of blades 10 is 60°. In this way, sufficient flow area can be left while shearing, which can effectively reduce the local resistance of the device . The central shaft 5 at both ends of the spoiler rotor 3 is rotationally connected with the stator casing through the sliding bearing 6, and the spoiler rotor 3 can rotate freely in the stator casing. Immediately after flooding the crude oil cold transport fluidization device, the stator shell is filled. T...

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

1. Technical field: [0001] 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: [0002] 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 in the co...
