METHOD FOR DETERMINING MINIMAL OUTPUT ENSURING DELIVERY OF BED FLUID FROM BOTTOM HOLE OF GAS WELLS AND GAS-CONDENSATE WELLS Russian patent published in 1999 - IPC

FIELD: gas production industry. SUBSTANCE: this relates to development of gas and gas-condensate deposits. According to method, output is determined individually for each producing well. In this case, carried out in each well are gas-dynamic investigations at stationary modes of filtration. Output is changed by increasing with discrete increments of pipe union diameter beginning with minimal value at which it is known that delivery of bed fluid from well bottom hole is impossible. Velocity of fluid flow is calculated at shoe of pump-compressor pipes. Then, according to mathematical formula given in description of invention, determined is value of minimal output which ensures delivery of fluid from bottom hole of bed and in compliance with found value, preset is technological mode of production which prevents self-killing of well. Application of aforesaid method increases production of gas and gas-condensate due to prevention of self-killing of well and consequently due to preventing idling of low-output wells with subsequent enhancing outputs of high-productive producing wells. EFFECT: high efficiency. 1 cl, 1 dwg
