Water content is an important indicator in oilfield production and crude oil processing, directly affecting the quality, storage, transportation and refining of crude oil. Controlling and monitoring crude oil water content helps improve production efficiency, prevent equipment corrosion and ensure the quality of the final product.

[0003] A Chinese patent discloses a dedicated tester for water content in crude oil (publication number: CN218824281U). The device is improved by having a detachable sampling tube and a leak detection device provided inside the device. The detachable sampling tube provided inside the device makes cleaning the device more convenient and efficient, and the leak detection device can detect the sealing of the device during operation to prevent oil leakage, greatly improving the practical performance of the device. However, the device still has the following defects:

[0004] The filter mesh used to filter crude oil impurities in the oil inlet pipe is difficult to disassemble and clean, so impurities easily accumulate on the filter surface and may cause pipeline blockage. In addition, the instrument used to detect the water content of crude oil is installed inside the pipeline and is in contact with the flowing crude oil for a long time, which may cause contamination or scaling of the sensor surface. Therefore, a special crude oil water content analyzer is proposed to solve the above problems. Utility Model Content

Figure 2 As shown, the spring 213 pushes the limit block 211 upward, thereby driving the lifting sleeve 210 to lift upward;

[0030] A sealing plate 202 is fixedly mounted on one end of the surface of the detection tube 201. The outer surface of the sealing plate 202 is fixedly mounted to the motor 203. The output shaft of the motor 203 passes through the motor 203 and the detection tube 201. The end of the output shaft of the motor 203 is fixedly connected to the stirring paddle 204. Figure 2 As shown, the motor 203 drives the stirring paddle 204 to rotate, thereby stirring the crude oil inside the detection tube 201, which helps to improve the uniformity of the crude oil and thus improve the accuracy of the detection;

[0031] The outer wall of one end of the detection tube 201 is fixedly connected to the second flange tube 208. The outer surface of the end of the detection tube 201 away from the second flange tube 208 is provided with a thread. The inner wall of the detection tube 201 and the side close to the thread are movably installed with a mounting frame 205. A sealing sleeve 206 is fixedly installed in the middle of the outer wall of the mounting frame 205. One side of the sealing sleeve 206 extends to the side of the mounting frame 205. The outer surface of the sealing sleeve 206 is against the inner wall of the detection tube 201. The inner wall of the mounting frame 205 is fixedly connected to a filter screen 207.

[0035] The working principle of this utility model:

[0036] When it is necessary to detect the water content of crude oil in the pipeline, the first flange pipe 101 and the second flange pipe 208 are installed between the pipeline. During the test, the sensor probe is inserted into the lifting sleeve 210, and the sensor pushes the lifting sleeve 210 downward, so that the spring 213 is pushed and contracted by the limit block 211, and the lifting sleeve 210 is located at the opening 212 and gradually descends into the interior of the detection tube 201, so that the crude oil can fully contact the sensor probe through the opening 212. After the test is completed, the sensor probe is moved upward, and the spring 213 releases its elastic potential energy to push the limit block 211 upward, so that the opening 212 is driven upward by the lifting sleeve 210 and the opening 212 is blocked by the plug-in tube 209.

[0037] When crude oil enters the detection tube 201, it is intercepted by the filter 207 to prevent impurities from affecting the measurement results when the crude oil passes through the sensor probe. When the filter 207 needs to be cleaned, the rotating ring 106 is unscrewed to the outside of the detection tube 201 and the delivery hose 102 is bent to ensure that the rotating ring 106 can be completely separated from the detection tube 201. Finally, the installation frame 205 can be removed from the end of the detection tube 201.

[0038] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
