ShengjiPetro has nearly 20-year’s history in manufacturing multiphase metering devices. It was a joint venture company of Lanzhou Haimo Technologies Co., Ltd. ShengjiPetro drafted sinopec’s flowmeter standards. ShengjiPetro 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.
How to quickly realize the integration of single-well
throttling and metering in oil fields?
Oilfield single-well metering is the largest and most tedious basic work in all metering work.
The data collected by single-well metering is mainly used for oil well production calculation, reserves control, production evaluation, and management, and provides data for the development of oil fields.
So online real-time metering of single wells in oil fields requires accurate, simple, and safe measurement devices.
The existing flow detection is usually measured by a metering station. The single-well liquid production enters the oil pipeline through the wellhead’s restrictor, and the oil well production fluid is transported to the dedicated metering flow station through the oil pipeline process, and the construction and maintenance cost of the metering station is very high. Only multiple oil wells can share a metering station to complete the measurement of each well through the switching interface, but it is impossible to provide real-time flow information for all wells. The equipment is large in size, high in cost, and inconvenient to install and use.
In response to this situation, Shengji Company has developed a single-well throttling and metering integrated device, which can not only realize the real-time online measurement of single wells, but also directly replace the original throttle to complete the throttling function.
The device includes a displacement sensor, a pressure sensor, a temperature sensor, a float, a device body, an upper flange, a bottom flange, and a data acquisition and analysis module. The device body is provided with an oil nozzle and a plug.
The oil nozzle connects with the throttle channel. The upper part of the throttle channel is provided with a vertical channel. The vertical channel is connected with the upper cavity.
The two sides of vertical channel are provided with bypass channels. The vertical channel and the bypass channel make the liquid flow form an M-shaped flow cross section. The exit is connected to the process interface.
1-displacement sensor, 2- pressure sensor, 3- temperature sensor, 4- upper flange, 5- device body, 6- float, 7- nozzle, 8- plug, 9- bottom flange, 10- vertical channel, 11-throttling channel, 12-process interface, 13-bypass channel, 14-upper cavity, 15-data acquisition and analysis module, R-inlet,C-outlet.
The well fluid enter from the inlet of the device body, after being throttled by the oil nozzle, flows upward along the vertical channel through the throttle channel, and push a float upwards, then enters the upper cavity through the annulus between the float and vertical channel, reach the outlet bypass channel and connect the manifold to the oil pipeline.
The impact force of the fluid entering from the inlet on the float and the gravity of the float itself form a pair of interaction forces and achieve dynamic equilibrium.
The flow rate of the fluid is related to the annulus area between the float and the vertical channel.
The higher the float, the larger the annulus area, and the greater the fluid flow, so the rise height of the float reflects the magnitude of the fluid flow.
In addition, the gas in the fluid will have a vortex effect near the annular gap between the float and the vertical channel.
The vortex effect will cause high-frequency vibration of the float. The vibration frequency of the float reflects the flow rate of the gas.
The device is compact, small in volume, high in metering accuracy and low in price, and realizes real-time online metering of a single well.
The single-well flowmeter and the throttle are combined together, and the same device is used to complete the flowmeter and throttle functions at the same time.
