Problems solved by technology
[0010] The centrifugation method first needs to measure the free water in the sample. This process is cumbersome to operate, and the oil-in-water emulsion is measured as free water, resulting in errors in the test results; the centrifugal dehydration time is 45 minutes, which consumes a lot of electricity and costs High; due to the complex formation process and long life of the water-in-oil emulsion, the combination of water and oil is quite tight, and the centrifugal force is completely unable to separate the emulsified water of crude oil from the crude oil, resulting in errors in test results and low measurement accuracy

Description
technical field [0001] The invention belongs to the technical field of the petroleum industry, and in particular relates to a device for measuring the water content of crude oil by electrolytic centrifugation and a measuring method thereof. Background technique [0002] In the process of crude oil production, research and development, and processing, it is necessary to know the water content of crude oil at any time, so as to monitor crude oil production and grasp the dynamics of oilfield strata. , all need to know the water content of crude oil to control the whole production process. Detecting water content is of great significance to oilfield production and petroleum processing. [0003] At present, according to the method classification of water content measurement principle, the existing domestic and foreign crude oil water content measurement instruments are divided into the following categories: [0004] 1. Distillation water content analyzer [0005] The principle...
