Embodiment Construction

[0022] Below in conjunction with example and accompanying drawing, the present invention will be further described.

[0023] The basic structure of the spinner in the gathering pipeline is as follows: figure 1 As shown, the swirler 4 is composed of swirl vanes 1 and guide columns 2 whose diameter is smaller than the inner diameter of the gathering pipeline. The swirl vanes 1 are evenly distributed on the guide column 2 along the circumferential direction. In order to reduce the flow resistance, the blades are linear at the entrance to guide the flow, and then the blades rotate around the guide column 2 at a certain angle. The gap between the swirl blade 1 and the pipe wall of the gathering and transportation pipeline is very small, and the diversion column 2 and the gathering and transportation pipeline 3 form concentric cylinders. Depending on the number of swirl blades, the helix angle of the swirl blades, the ratio of the diameter of the guide column to the diameter of the...

Abstract

The invention discloses a vortex device and application of the vortex device in transportation of high water content crude oil. The high water content crude oil is not heated to be transported by a vortex generator; oil and water phases flow through the static vortex generator to generate tangential velocity and form water film ring flowing in a pipeline by using different densities; and the crude oil is enclosed by the water layer and is not deposited on the wall, so that the on-way resistance loss is reduced, the transportation is smoother, the energy consumption of heating the oil water mixture by a traditional method is reduced, and the greenhouse gas emission is reduced. The vortex device is simple in structure; and through the device, the purpose of gathering and transportation the crude oil by using the energy of the pipeline without heating can be realized, the energy is saved, and the economic benefit is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of crude oil gathering and transportation technology, in particular to a vortex device and its application in the transportation of crude oil with high water content. Background technique [0002] Crude oil gathering and transportation is the process of collecting, transporting and processing oil and gas produced by scattered oil wells into qualified crude oil. At this stage, most of the crude oil produced by new and old oilfields in my country has the characteristics of high freezing point and high viscosity, and the average comprehensive water content has reached 86.0%, and the output of old oilfields with high water content accounts for 70% of the total domestic output. In order to ensure the normal gathering and transportation of crude oil, it is usually necessary to heat the crude oil. The gathering and transportation costs such as heating and pump power of the traditional gathering and transportation p...
