Abstract
1. Способ эксплуатации залежи углеводородов, включающий прокладку горизонтальных скважин, перфорацию их и формирование трещин с помощью гидравлического разрыва пласта, проводимого последовательно, начиная с конца, дальнего от вертикального участка скважины, с изоляцией каждого перфорируемого интервала от остальной колонны пакером, отличающийся тем, что гидравлический разрыв пласта в каждом интервале осуществляют с последовательно уменьшающейся величиной давления разрыва от максимально возможной расчетной его величины, не превышающей предельно допустимую величину для пород данного пласта, в первом интервале до минимально возможной в последнем. ! 2. Способ эксплуатации залежи углеводородов по п.1, отличающийся тем, что горизонтальный участок расположен или в покрышке продуктивного пласта, или в верхней части продуктивного пласта, или в самом продуктивном пласте, удаленном от обводненной части продуктивного пласта на расстояние не менее 2-5 м. ! 3. Способ эксплуатации залежи углеводородов по п.1, отличающийся тем, что пакеры для изоляции перфорируемых интервалов спускают на гибкой трубе, а проведение гидравлических разрывов и подготовительно-заключительные операции гидравлического разрыва осуществляют за один цикл путем перемещения гибкой трубы по горизонтальному участку горизонтальной скважины, начиная с конца, дальнего от вертикального участка горизонтальной скважины.1. A method of operating a hydrocarbon deposit, including laying horizontal wells, perforating them and forming cracks using hydraulic fracturing, carried out sequentially, starting from the end farthest from the vertical section of the well, with isolation of each perforated interval from the rest of the column with a packer, characterized in that hydraulic fracturing in each interval is carried out with a successively decreasing value of the fracture pressure from its maximum design value, not exceeding the maximum permissible value for the rocks of a given formation, in the first interval to the minimum possible in the latter. ! 2. The method of exploitation of a hydrocarbon deposit according to claim 1, characterized in that the horizontal section is located either in the cover of the reservoir, or in the upper part of the reservoir, or in the reservoir itself, at a distance from the flooded part of the reservoir at least 2-5 m.! 3. The method of operating a hydrocarbon deposit according to claim 1, characterized in that the packers for isolating the perforated intervals are lowered on a flexible pipe, and hydraulic fracturing and preparatory-final hydraulic fracturing operations are carried out in one cycle by moving the flexible pipe along a horizontal section of a horizontal well, starting from the end farthest from the vertical section of the horizontal well.
