At present, in oil production wells of all oil fields in the world, the oil yield and the oil production are the most important basic data for oil field production, and most of the oil fields in China adopt secondary tertiary oil displacement operation, secondary oil extraction adopts a water drive technology, and tertiary oil extraction adopts an ternary combination drive technology. Similar technologies are mostly adopted for deep oil extraction in large oil fields such as Daqing oil fields, Jilin oil fields, Tarim oil fields, Shengli oil fields and the like in China due to aging of the oil fields.

In order to monitor the production water amount of an oil well in real time, it is necessary to accurately control the oil production amount of the oil well in each oil field, and it is necessary to periodically measure the water content of the oil well production liquid.

A conduit intermediate the first static mixer 232 and the second static mixer 234, which is a first transition conduit 236; the pipe diameter of the first transition pipe 236 is changed from large to small to a preset pipe diameter, and the inner wall of the first transition pipe 236 is in smooth transition. The concrete structure of the moisture content sensor in this embodiment is not limited, and the moisture content sensor in the prior art is adopted.

For example, the pipe diameter of the second pipeline is 20cm, and the pipe diameter of the first transition pipeline can be uniformly changed from 20cm to 10 cm. The preset pipe diameter can be selected according to specific operation environment; the present embodiment does not limit the numerical value of the preset pipe diameter.

In the first transition conduit 236, when the liquid in the conduit is restricted from flowing through the reduced flow cross section, the flow rate of the fluid is increased, and the fluid is fully mixed by the first static mixer and the second static mixer. The static mixers are respectively arranged in different pipe diameters, and the flow state of liquid in the pipes is changed by utilizing the mixing unit bodies fixed in the pipes so as to achieve the purposes of good dispersion and sufficient mixing among water, oil and gas, thereby improving the accurate measurement of the water content.

The pressure gauge 233 constantly monitors the pressure condition and is connected to the controller 1. When the controller 1 judges that the pressure exceeds the defined pressure, the first electric valve 221 is immediately controlled to be opened for pressure relief protection, and the measurement process is suspended; after the pressure in the pipeline returns to the normal range for a period of time, the next operation is started.

When the water content is measured, the device can increase the flow rate of produced liquid through the change of the pipe diameter of the first transition pipeline 236 from large to small, and two static mixers are matched to ensure that the produced liquid which is fully mixed and then is accurately measured; compare traditional measuring device, the utility model discloses a required part of device is less, simple structure, small, take up an area of fewly, and it is higher to measure the accuracy moreover.

Similarly, the pressure gauge 233 constantly monitors the pressure condition, is connected to the controller 1, and immediately controls to open the first electric valve 221 to perform pressure relief protection when the controller 1 judges that the pressure exceeds a defined pressure, and the cleaning process is suspended; after the pressure returns to the normal range for a while, the cleaning operation is performed.

In a cleaning state, the device can increase the flow rate of produced liquid through the change of the pipe diameter of the first transition pipe 236 from large to small, and the water content sensor 235 is washed by high-speed liquid; meanwhile, the cleaning ring 331 is used in a reciprocating motion, and the two modes are adopted simultaneously, so that the attachments on the surface of the water content sensor 235 are cleaned.
