| titleOfInvention | Method of acquisition and transportation of production of oil wells with high gas factor and system for its implementation |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: method involves removal of production of oil wells from group measuring plants under wellhead pressure, its passage through jet equipment provided with nozzle, receiving chamber, mixing chamber and diffuser, its further supply to separation assembly where the above product is separated into gas-containing separation product - gas-oil-water phase supplied to the pressure pipeline and water-oil part performing the function of working medium which is supplied to the power unit inlet and from its outlet - to the nozzle of the jet equipment. As jet equipment there used is jet device, and before the product of oil wells is passed through the above jet device, its turbulisation is performed. Then it is supplied to the receiving chamber of jet device and then through mixing chamber of the latter and its diffuser to separation assembly with two separation stages, which consists of in-series arranged hydraulic cyclone and gravitational separator. At that, there performed is subsequent separation of the product of oil wells in hydraulic cyclone into free gas discharged to pressure pipeline and gas-oil-water liquid supplied to gravitational separator where the above liquid is divided into gas-oil-water phase supplied to pressure pipeline and water-oil part performing the function of working medium which is supplied through pipeline and auxiliary process equipment providing stable operation of power unit and jet device to the power unit inlet, and from its outlet to the nozzle of jet device. The proposed system contains intake line 1 of the product of oil wells from group metering units 2, jet device 3, turbuliser 4, separation unit consisting of in-series arranged hydraulic cyclone 5 and gravitational separator 6, and power unit 7. Line 1 is connected to the input of transported liquid of turbuliser 4. After turbuliser 4 the product homogeneous as to density is supplied through receiving chamber 8, mixing chamber 9 of jet device 3 to diffuser 10 which is connected to input 11 of hydraulic cyclone 5. In the latter the separation of oil well product is performed into free gas discharged from upper part of hydraulic cyclone 5 to pressure pipeline 12, and gas-oil-water liquid supplied via discharge 13 to gravitational separator 6. In the latter there performed is its separation into gas-oil-water phase supplied via discharge 14 to pressure pipeline 12 and water-oil part - working medium - supplied through discharge 15 to pipeline 16. In order to ensure stable operation of power unit and jet device, pipeline 16 is equipped with auxiliary process equipment, for example foam suppressant 17, and/or heat exchanger 18, and/or filter 19. Pipeline 16 is connected to power unit 7 the outlet of which is connected to nozzle 20 of jet device 3. n EFFECT: enlarging possibilities and improving reliability of acquisition and transportation of the product of wells with high gas content of 100 to 1000 and more m 3 per one tonne of the product and at available non-uniform alternating flow of oil wells products with liquid-gas sequence, at simultaneous possibility of stable and uninterrupted operation during long time period at the provided transportation of the above product, mainly in quantity of hundreds and thousands of cubic metres per hour in conditions of gas blocks. n 14 cl, 1 dwg |
