Изобретение относитс к трубопроводное транспорту нефти и может быть испойьзованр дл транспорта газожидкостной смеси продукции скважин на нефт ных месторождени х. Известен способ транспорта газожид костной смеси продукции скважин на нефт ных месторождени х, согласно KOTOpow газожидкостную смесь nocnie выхода из скважины подвергают обработке дёэмульгатором,а на конечном участке трубопровода раздел ют на газовую и жидкую фазы, отбир1аемав в пункты сбора отдельными потоками 1 Известен также способ ранспо та продукции скважин на нефт ных месторождени х , согласно KOTopoKV газожйдкрстную смесь раздел ют на газовую и жидкую фазы у усть скважины, а п® рекачку полученных фаз на пункты осуществл ют после их предваритель нбгс) йк ешейи по одному трубопрово ду 12. Недостатком этих способов вл ютс значительные энергозатраты, оЙус ювленные совместным транспортом газовой и жидкой фаз.: Это объ сн етс образованием в та ких потоках вторичных течений на йо- верхности жидкой фазы (волн, вихрей. отрывога tf распылением жидкой фазы), .вызывающих повышение сопротивлени движению потока. Цель изобретени - снижение энергозатрат . Это достигаетс тем, что перекачку фаз ведут раздельными потоками поочередно , по мере заполнени рабочего объема разделител жидкой фазой. Кроме того, в поток жидкой фазы ввод т дезкульгатор. На чертеже изображено устройство, лри помс ци которого осуществл ют предлагаемый способ. Газожидкостна смесь (газ, нефть и вода) из скважины по трубопроводу I поступает в разделитель (емкость) 2, где происходит разделение смеси на газовую и жидкую (нефть и вода) фазы. По достижении границей раздела газ - жидкость верхнего заданного уровн , запорное переключающее устройство 3, например, (трехходовой кран) соедин ет с трубопроводом 4 нижнюю полость разделител . Это обеспечивает вытеснение из разделител ЖИДКОЙ фазы. При достижении границей раздела газ -жидкость нижнего заданного уровн , с трубопроводом соедан етс верхн полостьThe invention relates to pipeline transportation of oil and can be used for transporting a gas-liquid mixture of well production in oil fields. A known method of transporting gas-liquid bone mixture of well production at oil fields, according to KOTOpow, gas-liquid mixture of nocnie exit from the well is subjected to demulsifier treatment, and in the final pipeline section it is divided into gas and liquid phases, selected by separate flows to collection points 1 This production of wells at oil fields, according to KOTopoKV, the gas-fluid mixture is divided into the gas and liquid phases at the wellhead, and p® pump the obtained phases into points after their completion. nbgs) doubles drainer through one pipeline 12. The disadvantage of these methods is the significant energy consumption associated with the joint transport of the gas and liquid phases: This is due to the formation of secondary currents on the surface of the liquid phase (waves, vortices (tf spraying liquid phase), causing an increase in flow resistance. The purpose of the invention is to reduce energy consumption. This is achieved by transferring the phases in separate streams alternately as the working volume of the separator is filled with the liquid phase. In addition, a desculver is introduced into the liquid phase stream. The drawing shows a device in which the proposed method is carried out. The gas-liquid mixture (gas, oil and water) from the well through pipeline I enters the separator (tank) 2, where the mixture is separated into gas and liquid (oil and water) phases. When the gas-to-liquid interface reaches an upper predetermined level, a locking switching device 3, for example (a three-way valve) connects to the pipeline 4 the lower cavity of the separator. This ensures that the liquid phase is expelled from the separator. When the gas-liquid reaches a lower predetermined level, the upper cavity is connected to the pipeline
