Embodiment Construction

[0023] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0024] Oil and water have the characteristics of incompatibility and the fact that oil is light and water is heavy. The crude oil with high water content will form oil-water mixed layer continuous phase and water layer continuous phase after static precipitation. The water content analyzer in the present invention utilizes the difference in dielectric constant between oil and water, uses the capacitive reactance method to measure the height of the liquid level and the height of the oil-water interface, and then measures the water content in the oil-water mixed layer to calculate the water content of the oil sample.

[0025] Such as figure 1 as shown, figure 1 It is a structural diagram of the crude oil water content measurement and analysis sys...

Abstract

The invention provides a water content measurement and analysis system for crude oil. The water content measurement and analysis system for crude oil includes a sampling controller, a sampler, a sample barrel and a water content analyzer. Under the control of the pipeline, the sample is taken out from the pipeline several times, and the sample is transported into the sample barrel, the sample barrel is connected to the sampler to store the sample, the moisture analyzer is connected to the sample barrel, and the The sample in the sample barrel is analyzed for water content, and the water content of the sample is measured. The water content measurement and analysis system of crude oil has the advantages of multiple sampling times, multi-layer sampling, limiting liquid backflow into the pipeline and anti-splashing function at the outlet. When performing sample analysis, it has the advantages of short measurement time and high measurement accuracy. , full sample analysis, simple operation, and can reduce energy consumption and air pollution.

Description

technical field [0001] The invention relates to a water content measurement and analysis system in oil and a wellhead automatic sampling system, in particular to a crude oil water content measurement and analysis system. Background technique [0002] The accuracy of the water content test of crude oil in oilfield production fluid plays a very important role in timely grasping the production status of oil wells, optimizing reservoir production parameters, adopting scientific operation measures, realizing crude oil production pressure transmission, and improving oil recovery. There are many methods for measuring the water content of crude oil in the national oil industry. The traditional manual measurement method is mainly through the method of distillation test. From the perspective of distillation alone, the measurement accuracy of distillation test method is high. In the case of produced fluid (high water content), there are many problems, such as: poor sampling representat...
