Oilfield Multiphase Flow Meter Device
Oilfield Multiphase Flow Meter Device
Product DescriptionShengji has nearly 20-year’s history in manufacturing multiphase metering devices. It was a joint venture company of Lanzhou Haimo Technologies Co., Ltd. Shengji can design and manufacture targeted multiphase metering device according to complex field conditions (such as heavy oil, high gas content oil, foamy crude oil and serious slugging oil, etc.). The products has already been widely used in home and abroad oilfields.
Key Feature
1.Accurate measurement of oil, water and gas.
2.Friendly interface.
3.Easy operation.
4.Modular design featuring latest technology in measurement systems.
5.Remote data transmission, allowing for real-time data acquisition and digitization of the oilfield.
Specifications 1.Universal Gas and Liquid Automatic Metering DeviceFor the complex conditions in Venezuela MPE3 oilfield including high viscosity oil, high gas content oil and foamy crude oil, Shengji company had designed a brand-new solution for multiphase flow meter. This solution uses dual splitter, weight measurement method and built-in high efficiency cyclone separating device to engage the meter has the characteristic of wide adaption of measurement range, high accuracy, wide range, operation stability.

 | While the import three-way valve opened for the left separator, export three-way valve opened for right separator. Then liquid level of left separator started to increase. When it reached to setting position, ΔP would be measured. ΔP=mg/S M is the mass of liquid column in the separator, g is acceleration of gravity, S is sectional area of separator. The mass of liquid column in the separator can be calculated by this formula and also obtain the flow of well from the change of the mass of liquid column. Control system controls alternate measurement of left and right separator, thus implement continuous measurement of well. After the measurement, intelligent control system is able to calculate the run of oil in the setting time to convert to daily oil production.

External liquid (gas and liquid) first pass through multiport valve, measure the liquid pipeline, choose relevant metering process (time-sharing automatic selection or manual selection). Gas and liquid flow into the device, first entering into desander (to adapt the application of sand-content crude oil, there is the matched desander in the system, which can clean the sand periodically), heat-exchanger, and then come to vertical two-phase separator, make most gas separation, enter into horizontal separator, make gas-content liquid separation, flow out the separated gas and liquid through different pipelines, there are metering device on the pipelines to measure the gas and liquid ( there are an area for liquid accumulation in the separator to adapt low yield and discontinuous liquid).

Fundamental Diagram
1.Measuring the displacement of floater and vibration parameter to obtain flow signal.
2.Different fluid has different reaction results of applied force. More precise results will be obtained by measuring the displacement of floater, vibration parameter and assists with adjustment of pressure and temperature parameter.
3.Continuous 2-phase measurement, measuring liquid and gas at the same time;
4.It adopts section throttling principle, less pressure-loss of equipment and wide flow range.
5.The equipment adopts embedded computer. It has great human-computer interface and communication protocol which reaches 6.the digitization requirement of oilfield.
7.Less moving parts, more reliable operation.
Multiple Phase Flow Lab
The laboratory is Sinopec‘s only national multiphase flow laboratory, which can achieve the whole gas, whole liquid and a variety of proportion of gas-containing test, the maximum amount of tesingliquid can reach 7000m3/d.
