Mobile oil and gas continuous metering device
The Mobile oil and gas continuous metering device is used for the multiphase separation and measurement of oil well output，which is independently developed by our company. It has obtained multiple patents (utility model patent, patent certificate number: ZL 2017 2 1191366.7/ ZL 2018 2 2159752.9). It is used for the measurement of well output from remote wells and single well of oil well without design interval. 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 require the data in time etc. It facilitates timely access to objective data to analyze and study the output 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.
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.
