Description
Известен способ отбора и подготовки рабочего агента дл газолифтной добычи нефти, заключающийс в том, что из добываемой нефтегазовой смеси отдел ют газовую фазу,затем газ, предназначенный дл газлифта, сжимают до необходимого давлени , после чего охлаждают его до температуры, при которой осуществл етс осушка газа от вод ных паров.A known method for the selection and preparation of a working agent for gas-lift oil production consists in separating the gas phase from the extracted oil and gas mixture, then the gas intended for gas lift is compressed to the required pressure, and then cooled to the temperature at which drying takes place. gas from water vapor.
Дл осуществлени подготовки и отбора рабочего агента нефтепромыслового газа по известному способу требуютс большие капиталовложени , так как существующие компрессорные станции сложны по своей конструкции , имеют высокую стоимость, сложны в обслуживании.To carry out the preparation and selection of the working agent of the oil field gas, according to a known method, large investments are required, since the existing compressor stations are complex in design, have a high cost, and are difficult to maintain.
Сложно также однотрубное транспортирование продукции скважин до центрального сборного пункта, так сжатие газа и создание напора дл перекачки нефти производитс раздельно компрессорами и насосами.It is also difficult to transport one-pipe production of wells to the central collection point, so gas compression and creation of a head for pumping oil is carried out separately by compressors and pumps.
С целью упрощени и удешевлени процесса газлифтной добычи по предлагаемому способу подготовки и отбора рабочего агента дл газлифтной добычи нефти нефтепромысловый газ сжижают совместно с добываемой из пласта жидкостью, после чего отдел ют от нее газ при рабочем давлении сжати .In order to simplify and reduce the cost of the gas-lift production process according to the proposed method of preparing and withdrawing a working agent for gas-lift oil extraction, oilfield gas is liquefied together with the fluid produced from the reservoir, after which the gas is separated from it at an operating compression pressure.

Из емкости 2 смесь поступает на компрессор-насос 3, откудаThe pump I enters the buffer tank 2, which is designed to smooth out the pulsation of the gas-liquid flow. From tank 2, the mixture enters the compressor-pump 3, from where

Отсепарированный газ подаетс на установку осушки 5, откуда распредел етс по газлифтным скважинам, а нефть из сепаратора поступает в напорный нефтегазопровод 6, в который также сбрасываютс излишки газа высокого давлени , остальна часть продукции скважин, не участвующа в цикле подготовки газа дл газлифтной добычи нефти, откачиваетс компрессором-насосом 7.The separated gas is supplied to the drying unit 5, from where it is distributed through gas-lift wells, and the oil from the separator enters the discharge oil and gas pipeline 6, into which excess high-pressure gas is also discharged, the rest of the well production not participating in the gas preparation cycle for gas-lift oil production, pumped out by compressor-pump 7.
