The invention relates to measuring the flow rate of oil and gas and gas condensate wells. Devices for measuring well production are known, which contain flow lines of wells, a common collector, a metering and switching unit, a multi-way switch connected to the flowlines of the well and a metering unit, the control unit 1. The disadvantage of these devices is the lack of measurement capability in one metering and switching setting of flow rates of wells with different working pressures. Closest to the invention to the technical essence is a device for measuring. well flow rate, containing well flow lines and common low and high pressure common collectors, switching actuator mounted on the flow line of each well, one outlet of which is connected to the common manifold of the corresponding working pressure and the other outlet to the filling manifold, metering and switching unit and a well control and measurement unit 2. A disadvantage of the known device is the unreliability in operation due to the complexity of its execution, due to the presence of a large t he switching executive bodies - two constipation GOVERNMENTAL executive authority for flowline each well, one of which is directed in the production wells common header corresponding working pressure, and others - the production wells through fill manifold zamernopereklyuchayuschuyu installation. The large number of shut-off actuators complicates and, accordingly, reduces the reliability of the control systems of the switching actuators as well. The purpose of the invention is to increase the reliability of the device for measuring the flow rate of a well. The goal is achieved by the fact that a device for measuring wells, containing flow lines of wells, common collectors of low and high operating pressures, is installed on the flow line of each well a switching body, one output of which is connected to a common collector of the corresponding working pressure, filling manifold , a metering and switching unit and a well flow rate control and measurement unit, the switching actuator is designed as a distribution valve, and A collector in the form of two filling lines corresponds to low and high working pressures, each of which is equipped with a shut-off actuator connected to the well control and flow measurement unit, the input of each of which is connected to a different outlet of the distribution valve of all wells of the corresponding working pressure, the output of which is connected to metering -Switching installation. The drawing shows a schematic diagram of the proposed device for measuring the flow rate of wells. The device contains discharge lines 1 and 2, respectively, of wells of low and high operating pressures (three wells of low and high operating pressures are shown each). Flow lines 1 of low pressure wells are connected to the inlet of distribution valve 3, and flow lines 2 of high pressure wells are connected to the input of distribution valve 4. Some outputs of distribution valves 3 and 4 are connected respectively via filling lines 5 and 6 and shut-off actuators 7 and 8 to the metering and switching unit 9, and the second outputs of the distribution valves 3 and 4 are connected respectively to the common low pressure collector 10 and to the common high pressure common collector 11. Distributive valves 3 and 4, shut-off actuators 7 and 8, and a metering and switching unit 9 are fitted to a unit 12 for controlling and measuring well production. The device works as follows. In the operating mode, gas-liquid products of low and high working pressure wells through the corresponding lines 1 and 2 and distribution valves 3 and 4 enter the corresponding common collectors 10 and 11. When measuring the flow rate of the low working pressure, the command from the well control unit 12 is measured and switching of the distributor body 3 and opening of the shut-off actuator 7, in which the production of this well stops flowing into the common low pressure manifold 10 and is directed through the bottom The main line 5 is connected to the metering and switching unit 9. The control and well flow measurement unit 12 together with the metering and switching unit 9 measures the low pressure well flow. At the end of the well flow measurement, a reverse switch command is sent from the well control unit 12 and the well flow measurement distribution valve 3. At the same time, the production of this well is again directed to the common low pressure manifold 10.

The flow rate of other low operating pressure wells is measured similarly.

At the completion of the measurement of the flow rate of the low working pressure, the control and measurement of the flow rate of the wells 12 is given a command to close the stop valve 7.

To measure the flow rate of the high working pressure, a command is sent from the control unit 12 and the measurement of the flow rate to switch the distribution valve 4 and open the shut-off actuator 8, at which the production of this well stops flowing into the common high-pressure collector 11 and

is directed through the filling line 6 and the open shut-off valve 8 to the metering and switching unit 9.

At the end of the measurement of the flow rate of the well, the control unit 12 and the measurement of the flow rate of the wells are given a command to reverse switch the distribution valve 4 of this well to a high operating pressure.

After measuring the flow rate of all the high pressure wells, the control unit 12 and measuring the flow rate of wells are instructed to close the stop valve 8.
