Abstract
Способ разработки газонефтяных залежей, включающий бурение горизонтального ствола добывающей скважины в нефтяной части пласта и горизонтально-восходящего ствола, пересекающего газонефтяной контакт, перфорацию эксплуатационной колонны со вскрытием нефтяной части и газовой шапки, подъем пластовых флюидов на поверхность, в том числе за счет естественного газлифта, отличающийся тем, что перфорацию эксплуатационной колонны в газовой шапке осуществляют в двух противоположных частях скважины в пределах отдельно взятого пласта, управление перетоками газообразных и жидких флюидов в скважине между различными интервалами перфораций выполняют с помощью регулируемых с поверхности перепускных устройств, при этом добычу газа в заданных контролируемых объемах осуществляют независимо из одного или двух интервалов вскрытия газовой шапки как по заколонному пространству, так и по насосно-компрессорной трубе для создания газлифтного режима подъема жидкости на поверхность, при этом решают задачу контроля перемещения газонефтяного контакта, когда добычей газа создают в газовой шапке воронку депрессии над районом добычи жидких флюидов в нефтяной части, тем самым поддерживают стабильность газонефтяного контакта с отсрочкой времени формирования конуса газа, при этом ствол скважины в нефтяной части проводят на расстоянии от газовой шапки не менее ½ толщины нефтяной части.A method for developing gas and oil deposits, including drilling a horizontal wellbore of an producing well in the oil part of the formation and a horizontally ascending well that crosses the gas-oil contact, perforating the production string with opening the oil part and the gas cap, raising formation fluids to the surface, including due to natural gas lift, characterized in that the perforation of the production string in the gas cap is carried out in two opposite parts of the well within a single formation, control the flow of gaseous and liquid fluids in the well between different intervals of perforations is performed using surface-controlled bypass devices, while gas production in predetermined controlled volumes is carried out independently from one or two opening intervals of the gas cap both in the annular space and in the tubing to create a gas-lift mode of lifting the liquid to the surface, while solving the problem of controlling the movement of the gas-oil contact, when gas production is created in the gas PKE funnel depression over the area of liquid fluids in oil extraction portion, thereby supporting gas contact stability with a delay time of formation gas cone, and the wellbore in the oil portion is performed at a distance from the gas cap is not less than ½ the thickness of the oil portion.
