Problems solved by technology

[0003] At present, the water content analysis of oil well crude oil still adopts the distillation test method, which needs to collect crude oil samples on site and bring them back to the laboratory for water content analysis.
It is understood that there is currently no specific crude oil water content analyzer verification device in China, which can quickly and safely detect the water content of crude oil, and it can also use diesel oil and crude oil as the medium to verify various types such as capacitance method, radio frequency method, microwave method, etc. The accuracy of the plug-in crude oil water content analyzer can be carried to the site for verification work. At the same time, it can prepare standard crude oil water content oil samples from 0 to 100% of each point, and simulate the on-site crude oil water content analysis of oil field oil pipelines. Continuous measurement mode operation device

Abstract

The invention relates to a water-in-oil analyzer calibration device and method. A medium circulating system, a standard water-in-oil analyzer, a water-in-oil analyzer to be detected and a data processing unit are mounted in a box-type shell, a panel is arranged on the box-type shell, the standard water-in-oil analyzer and the water-in-oil analyzer to be detected are respectively electrically connected with the data processing unit, the data processing unit is electrically connected with the panel, and the panel is electrically connected with a computer host. The calibration device is ingenious in design, accurate to manufacture, light in weight and convenient to carry, does not have any effect on human bodies and environments, belongs to safe, environment-friendly and energy-saving products, meets safe and environment-friendly requirements and can rapidly detect the water content of crude oil samples of oil wells indoors, water-in-oil analyzers of different types are calibrated, the calibration device can be carried to a site and used for calibrating water-in-oil analyzers in operation, the calibration device solves the problem that standard water-in-oil samples at points of 0-100% cannot be exclusively prepared in oil fields, and operation of an online continuous measuring mode of the water-in-oil analyzers of on-site oil pipelines of the oil fields is simulated.

Description

technical field [0001] The invention belongs to the technical field of water content analysis of crude oil, and in particular relates to a verification device and method for a water content analyzer of crude oil. Background technique [0002] The water content of oil well crude oil is an important parameter of oil recovery and production. It is very important to grasp the change of water content of crude oil at the wellhead in time for the dynamic analysis, working status and production management of the oil well. The water content of crude oil is also an important parameter in the transfer measurement of crude oil. With the improvement of the scientific management level and automation degree of the petroleum industry, the instruments for online measurement of the water content of crude oil have been widely used, and the accuracy of the instrument for detecting the water content of crude oil is very important. urgent. [0003] At present, the water content analysis of oil w...
