The osiooMfCH is a useful model for the field of measurement technology and is designed for measuring parameters of 11 products and 1 oil producing oil and gas production in oil-producing industry and can be used to measure oil, gas and water in oil well production.

A device is known for measuring the flow rate of oil wells (I), comprising a vertical cylindrical separator with a hydrocyclone, equipped with sophisticated gratings that form measurement cavities, inside of which lower and upper and lower level sensors are placed at the side wall of the separator, pressure sensors, gas line are installed at different levels with a valve, combining into a common output collector, and the released liquid line is made in the form of a siphon and a mimroprocessor.

The measurement process of this device is based on the assumption that the measuring cavity will be constantly periodically filled and supported.

However, with a change in the correlation of the inflow and outflow rates, the liquid does not have time to leave the separator, the measurement technological cycle is violated, which does not allow with sufficient toxicity and fatigue to ensure the measurement of the entire volume of liquid coming from the squash,

A known method of measuring the flow rate of a gas-liquid stream (2) in which the flow of liquid SLEF is supplied to a measuring chamber filled in the form of two vertically mounted hermetic cylinders, connected to each other at the top of the pipeline and the flow rate and flow rate composing the flow of components are determined by the time of deflation and emptying time and cylinder filling time.

The disadvantage of this method of measuring the flow rate of a gas-liquid stream is that the fluid stream contains constant components, and, as you know, the production flow of wells has a cork mode, which is formed on the path from the bottom of the wells to the measurement object, and further, therefore, this method does not reliable data on the coadjunate composition of the liquid, which confirmed the study of this method of measurement in various oil fields.

 2 The essence of the useful moded z & ktchv, & kya. in that the device for measuring the parameters of oil well projections contains a measuring tank, which is designed as a technical one and equipped with a sliding shelf for separating gas from the liquid and a casher for separating the liquid from gas, an electric heater for heating the liquid to separate the water, a measuring scale for then the determination of the volume of liquid and the sensors of the poor and upper liquid level to determine the measurement time.

To measure gas, the device is equipped with a membrane gas meter. The measured fluid carrying parameter determination is pumped to the manifold by a pump through an assembly valve.

Figure L shows a general view of a device for measuring production parameters of low production wells. The production of an oil well through an inlet pipe and a gate valve (BB) is directed to the measuring capacity of EY.

Capacity Ш is made in the form of a technical measure and is equipped with drain shelves for separating gas of liquid and a droplet separator for separating liquid droplets from gas.

From tank Ш the gas is piped through the valve 38 and the sump passes through a gas meter G25, in which the amount of gas is measured and then through the pipeline the gas enters the torch §,

The separating liquid accumulates in the EY tank and, upon a signal from the liquid level sensor D, the liquid supply is manually shut off.

Before the production of the well is supplied, tank Ш is supplied with a demulsifier from the tank (B) through the valve (31) in the amount of 40 mlg,

After the accumulation of capacity, the EI liquid is produced:

-including heater electric OE;

-HEATING LIQUID to Tederatura 401-

- Sludge liquid for at least 2 hours.

After sludge, the volume of liquid is measured on the measuring scale of the tank количество the amount of liquid i volume units. At the same time, the amount of liquid in mass units is determined by the current signal from the pressure transducer and the calibration table.

Further, the measured boundary is determined by the interface between water and oil, and the water content of the soyavashna products is determined by the ratio o (b) of water and liquid.

Up to the amount of fluid and the time it takes to fill the tank, the well production rate is determined in total or mass units.

After determining the main: oraletrahs in the well, the pump N is pumped out through the Cl valve and valves (37) to the common well encoder, the device returns to its original state.

For safe operation, the device is equipped with a manometer, lamps, electric heater and fan.

A drainage tank is located in the frame of the technological unit of the device. J. 2. Sources of information; The author's certificate I1553661A1 was registered on December 1, 2012. Patent f 1777446, author's certificate and I777446AI was registered on May 18, 1993.
