Description

technical field [0001] The invention relates to a water content detection and control system of an oil pipeline based on a wave detection and rectification circuit, in particular to a water content detection and control system of an oil pipeline based on a wave detection and rectification circuit, which belongs to the field of detection and control. Background technique [0002] At present, the water content of crude oil is one of the key indicators related to the economic interests of buyers and sellers. Although the various minerals in crude oil are diverse and complex, the factor that most affects the measurement accuracy of the water content analyzer is the probe hanging of the water content analyzer. Wax, due to the great difference in the wax content of crude oil in various oilfields and the difference in transportation temperature, the probe of the water content analyzer will produce wax hanging phenomenon irregularly. After the probe is waxed, the wax film outside th...

Problems solved by technology

[0003] At present, most of the oil pipelines in China adopt the method of measuring water content by opening on the side of the oil pipeline, and fixing the probe of the water content detector through the flange. If there is wax hanging on the probe, it is necessary to remove the flange after the pipeline is stopped. For cleaning treatment, a large amount of solvent oil or cleaning agent is required in the cleaning process, which not only increases the cleaning cost but also pollutes the environment

In addition, due to the high approval authority for the stop of the water meter, when the probe of the water content analyzer needs to be cleaned, if the stop of the water meter cannot be approved, the data measured by the water content meter is completely useless at this time. Therefore, this type of water meter is basically in a dead state.

Another method is to add a circulating bypass to the oil pipeline, extract the crude oil from the main oil pipeline, pass through the circulation pump, stop valve, and oil bypass pipe, and then forcefully circulate it back to the main oil pipeline. It is installed on the bypass pipe of oil delivery. In this method, the probe of the water content analyzer can be removed and cleaned by closing the shut-off valve under the condition of non-stop delivery. The thickness of the wax is irregular, it is difficult to clean the wax layer in time, and the measured data is still of little practical value

[0004] If the water content of crude oil is not detected accurately, it will directly affect the dynamic analysis of oil wells and oil layers, destroy the heavy electric field of the electric dehydrator, reduce the dehydration effect, and cause a lot of energy waste for crude oil collection and transportation

Therefore, the detection of the water content of crude oil is very important and has always attracted much attention. Various measurement methods have been proposed successively, and different forms of water content test instruments have been designed. There is always a lack of a simple, fast, accurate and practical prediction model
