Dynamic conductivity testing device for oil-water mixture and usage thereof

Abstract

The invention relates to a dynamic conductivity testing device for oil-water mixture and usage thereof. The device comprises a test section, a fluid controller, a circulating pump, a test liquid storage tank and a test liquid circulating pump, wherein one end of the test section is connected with the fluid controller while the other end is connected with the test liquid storage tank, the fluid controller is connected with the test liquid storage tank through the test liquid circulating pump, the top of the test liquid storage tank is provide with an air inlet and an air outlet, the bottom of the test liquid storage tank is provided with a test liquid outlet and a waste test liquid outlet and a stirrer is arranged inside the test liquid storage tank. The device overcomes the problems that when an existing static conductivity testing method is applied to testing the conductivity of the oil-water mixture, the liquid is layering, test conditions are greatly different from actual working conditions, reproducibility of measuring results is poor and the like; the oil-water mixture is prevented from being layering in standing, and the test conditions are closer to the actual working conditions; the dynamic conductivity testing device has the advantages of stable test conditions which are also closer to the actual working conditions, and being capable of achieving a dynamic test on conductivity of the oil-water mixture.

Description

technical field [0001] The invention belongs to the technical field of conductivity testing, and relates to a conductivity testing device for simulating the transportation state of oil-water mixtures in pipelines, in particular to a method for evaluating the corrosion of oil-water mixtures on pipelines by measuring the conductivity of oil-water mixtures in a flowing state Corrosivity, a dynamic oil-water mixture conductivity test device and its application method that provide reference for corrosion protection of pipeline transportation. Background technique [0002] When the oil-water mixture is transported in the pipeline, when the water content is very low, the water is in an emulsified state in the oil-water mixture, and it is difficult to form a continuous water phase. The corrosion of the pipeline caused by the oil-water mixture is slight; when the water content reaches a certain After the numerical value, a continuous water phase will appear in the oil-water mixture, ...
