The multi-parameter metering device of oil well in metering room (hereinafter referred to as the device) is used for the multiphase separation and measurement of oil well output. The device is installed in the field metering room and is used for the multiphase measurement of each oil well’s output. The device can be matched with optional well valve set. Under the control of the system, the automatic switch and timing measurement of each well measurement port are achieved.It eliminates the process of manual reversing valve, and reduce the labor intensity of the staff. This device can effectively solve the realistic difficult problems in traditional measurement methods, such as poor intermittent sampling accuracy, large labor intensity and failure to reflect the data in time etc. It facilitates timely access to objective data to analyze and study the yield changes of the wells in the block of the unit, and provides a reliable basis for the dynamic management of reservoirs.

The successful development of the device provides a solution for the accurate measurement of multiphase flow under the condition of multiphase mixed transmission process for oil field production, and provides effective support and means for oil field production to realize the fine management of single wells, which is beneficial to promote the improvement of oil field production technology and management level in the oil extraction industry.

Working principle

When the oil well receives liquid, it can realize effective separation of gas-liquid phase by the gas-liquid cyclone separator. The separation controller automatically controls the liquid level and gas-liquid pressure difference, and the separated gas and liquid pass through gas flowmeter, mass flowmeter and pressure instrument respectively, and the accurate measurement of gas volume, liquid volume, oil volume, water content, system pressure, temperature and other parameters is realized.
