Embodiment 1

[0027] Such as Figure 1~3 As shown, a crude oil water content measuring device includes a pretreatment container 4, one end of the pretreatment container 4 is connected to the pipeline 1 through a pipeline, and the other end of the pretreatment container 4 is connected to a measurement system 21 through a pipeline, and the measurement system 21 includes from The first pressure sensor 9, the liquid level sensor 7, the temperature sensor 8 and the second pressure sensor 11 are arranged from top to bottom. The end of the measurement system 21 that is closer to the second pressure sensor 11 is provided with a first oil return port 25. The first The oil return port 25 is connected with the pipeline 1 through a pipeline. With this structure, the water content can be measured by the density method and the expansion method at the same time, and the accuracy is higher.

[0028] In a preferred solution, the pipeline between the pipeline 1 and the pretreatment container 4 is provided w...

Embodiment 2

[0038] Working principle: During the measurement process, the electromagnetic one-way valve 2 of the oil inlet is first opened, and the crude oil in the pipeline 1 is pumped into the sampling pretreatment container 4 through the first oil pump 3 for pretreatment. There is a heating unit, and the heating unit is used to remove the gas in the crude oil, and then stir the treated water and oil mixture evenly, and enter the draft pipe 22 through the sampling port switch 6 .

[0039] After entering the measurement device, the high-pressure spray port 5 can be opened and the pretreatment container 4 can be heated to clean the sampling pretreatment container 4 and prepare for the next measurement. After the cleaned liquid passes through the oil return port 19 of the pretreatment container, the electromagnetic one-way valve 14 of the liquid discharge port is opened, and the cleaning liquid is discharged into the pipeline 1 under the action of the return port pump 15 .

[0040]The proc...

Abstract

The invention provides a crude oil moisture content measuring device which comprises a pretreatment container, wherein one end of the pretreatment container is connected with a pipeline through a pipeline, the other end of the pretreatment container is connected with a measuring system through a pipeline, the measuring system comprises a first pressure sensor, a liquid level sensor, a temperaturesensor and a second pressure sensor which are arranged from top to bottom, and a first oil return port is formed in the end, which is close to the second pressure sensor, of the measuring system and connected with the pipeline through a pipeline. The crude oil moisture content is measured by utilizing the characteristics that the crude oil has different densities under different moisture content conditions and the volume of the crude oil changes under the conditions of the same moisture content and different temperatures, so that the influence of the temperature on a density method can be compensated, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum production measurement, in particular to a crude oil water content measurement device. Background technique [0002] At present, crude oil extraction has entered the middle and late stages. In the process of crude oil extraction, in order to be able to specify the corresponding extraction plan according to different working conditions, it plays a vital role in saving manpower, material and financial resources. [0003] Among many measurement standards, the water content of crude oil is particularly important. With the development of the petroleum industry, many changes have taken place in the detection of petroleum moisture content, and the overall development is high-precision, rapid, intelligent and comprehensive. At present, the commonly used techniques and methods mainly include density method, ray absorption method, capacitance method, electrical impedance method, tomography method, nuclea...
