(57) Abstract: The device is used in the oil industry for oil extraction. The upper portion of the container with the reagent is linked by pipeline with the annular space, the lower part is connected by a hose to a discharge line. The tube is provided with a control valve. Pipeline and flow line indicated' by-pass line. The gas pressure regulator is installed on the bypass line. Metered flow of the reagent in the flow line is the displacement of the reagent from the container by the gas from the annulus. The gas pressure in the annulus is supported by gas pressure regulator. The use of the invention improves the reliability, simplifies the design, reduces the energy input device for dosing a reagent into the flow line. 1 Il. The invention relates to the oil industry and can be used in oil production. To improve the efficiency of oil use different reagents and introduce them to different parts of the system recovery. Known metering installation type BR (Safin C. A., Mandrikov C. M., Shinkarev, S. A. Technology and technical means of chemical production processes. electronically unit, gear pump, controls, and management. The disadvantages of installations of BR are the complexity, intensity, economiccost in energy consumption, do not allow to dose at low feed rates of the reagent. Known more simple and cheap dosing device of the hydrostatic action (Safin C. A., Mandrikov C. M., Shinkarev, S. A. Technology and technical means of chemical production processes. - M.: VNIIEM, 1985, S. 38), Such a device includes a container of reagent which is connected with the annular space of the well and the reagent is dosed in the annular space by replacing it with gas from the annulus of the well. This dosing device is used as a drip feed of reagent is carried out by the action of gravity. Often clogged channel for dispensing the reagent. The device is not reliable, the device is difficult to manufacture and service. To increase reliability, simplify the design and reduce energy costs in the known device with a container for the reagent associated with the annular space of the bore of the pipeline, the pipe for dosing and filling of the reagent, HAZOP IGNOU line tube, equipped with a control valve, and the gas pipeline and flow line indicated in the bypass line, which includes a gas pressure regulator. This solution allows you to provide a dosage of a reagent in the flow line from the wellhead without any drive and pump through the use of gas pressure in the annulus of the well. This increases the reliability of the device for the dosage of reagent, reduced capital and operating costs. The drawing shows the proposed device. The device includes a production casing of the well 1, the pump-compressor pipe 2, flow line 3 slide 4, the container 5 for the reagent, the pipeline 6 with the valve 7, the bypass line 8 with the gas pressure regulator 9, the gauge 10, the tube 11 with a valve 12, a pipe 13 with the latch 14, the level indicator 15, the control taps 16. The device is assembled and operates as follows. Near the wellhead is installed, the container 5 for the reagent, which binds the pipeline 6 valve 7 with the annular space of the well between the production column wells 1 and pump-compressor pipe 2. uliuli valve 12 for dosing the reagent. In the discharge line 3 and the pipeline 6 is installed gauges 10 and are connected to the bypass line 8, on which is installed a gas pressure regulator 9. The container 5 is equipped with a pipe 13 with a valve 14 for filling the reagent, a level indicator 15 and a control taps 16 for additional control of the level of reagent or sample. After Assembly of the device on the proposed scheme, the container is filled with the necessary reagent by pumping it through a pipe 13. The capacity of the container and the quantity of the reagent is determined by considering the consumption of reagent and a predetermined period between refills. When the well annulus accumulated gas under pressure, supported by gas pressure regulator 9. The gas pressure regulator always maintains the gas pressure in the annulus and in the pipeline 6 is greater than the pressure in the flow line 3. Gas of the same pressure presses the reagent in the container 5. When this reagent under this pressure exceeds the pressure in the flow line, is displaced through the valve 12 and the tube 11 in the sliding line 3. Reagent consumption is controlled by the sensor 15 or the control taps 16. If necessary, the reagent consumption is regulated by p is metrov 10 and, if necessary, regulated by the gas pressure regulator 9. when adjusted position of the gas pressure regulator 9 for a certain gas pressure of excess gas is bypassed through the pipe 8 into the discharge line 3. In appropriate container for the reagent is equipped with a heater. The proposed device makes use of the pump and motor to dispense the reagent in the flow line. It regulates the flow rate of the reagent with the regulating valve and changing the value of the gas pressure in the container for the reagent. Thus, a simple device allows efficient use of the reagents in the extraction response with low capital and operating costs. Device for dosing the reagent discharge line containing a container for the reagent associated with the annular space of the bore of the pipeline, the pipe for dosing and filling of the reagent, characterized in that the pipeline connected to the upper portion of the container with the annular space, and its lower part is connected with the discharge line tube is provided with a control valve, and the gas pipeline and flow line indicated in the bypass line, which includes a gas pressure regulator.
