Shengli Oilfield developed a separator sand flushing device

A few days ago, the isolated third area of the isolated island oil production plant of Shengli Oilfield successfully developed a separator rotary sand punching device, which effectively solved the problem of
inaccurate oil measurement caused by the sand plugging of the vertical two-phase separator.
At present, the device is widely used in the isolated third area, which not only reduces the measurement error of a single well, but also greatly prolongs the sand cleaning cycle and reduces the labor intensity
.

The field test results of the device at the East 1-11 metering station of the injection and production management station 307 show that the average oil production time of the 13 oil wells after cleaning increased from a high 473.
5 seconds to 487.
7 seconds, and the average pump efficiency changed from 94.
8% to a more reasonable 78.
3%.

The device was used to clean up 8 separators in use at other metering stations of the 307 stations of injection and production management, and a large amount of grit was washed out, and the accuracy of oil measurement data was greatly improved
.

The vertical two-phase separator is the main equipment for oil well production measurement, and the size of its measurement error is directly related to the accuracy of
the oil measurement data.
Affected by the characteristics of oil reservoirs with high mud content, loose cementation and easy sand production in isolated island oilfields, the phenomenon of sand plugging of separators often occurs, which brings great difficulties
to normal oil measurement work.
More than 70% of the oil wells in the east 1-11 metering station of the 307 station of injection and production management in the isolated third area have different degrees of actual liquid volume exceeding the theoretical displacement
