Abstract

Изобретение относится к способам разработки залежей углеводородов, начиная с любого периода их добычи. Обеспечивает управляемость добычи углеводородов скважинами с псевдогоризонтальным и/или горизонтальным стволом в продуктивном пласте, обеспечивает повышение коэффициента извлечения нефти, предотвращает расформирование залежей нефти и предотвращает образование застойных зон. Сущность изобретения: способ разработки залежей нефти с помощью эксплуатации добывающих и нагнетательных скважин с горизонтальным или псевдогоризонтальным стволом, открытым в продуктивном пласте, усиливают продолжением обсадной колонны до конца этих стволов, цементированием всей обсадной колонны снаружи и равномерным распределением перфорации вдоль участка колонны в зоне всего горизонтального и/или части псевдогоризонтального ствола скважины. Создают равномерную депрессию или репрессию вдоль перфорированного участка с обеих сторон в нефтяной зоне, соответственно в обсадных колоннах добывающих или нагнетательных скважин. Располагают горизонтальные и/или псевдогоризонтальные стволы добывающих и нагнетательных строящихся скважин параллельно между собой, но поперёк преимущественного направления трещин в продуктивном пласте. Раздельно извлекают фракцию нефти от газоконденсата и газа из коллектора и закачивают в него объём термохимически подготовленного, насыщенного газом жидкого вытеснителя, равный объёму добываемой из него жидкости, с объемной скоростью, не приводящей к гидроразрыву продуктивного пласта в нефтяной зоне, а также закачивают подогретый газ в газовую зону коллектора при температуре выше пластовой.The invention relates to methods for the development of hydrocarbon deposits, starting with any period of their production. It provides controllability of hydrocarbon production by wells with a pseudo-horizontal and / or horizontal wellbore in the reservoir, provides an increase in oil recovery, prevents the dissolution of oil deposits and prevents the formation of stagnant zones. The inventive method of developing oil deposits by operating production and injection wells with a horizontal or pseudo-horizontal wellbore open in the reservoir, is enhanced by continuing the casing to the end of these trunks, cementing the entire casing from the outside and evenly distributing the perforations along the section of the column in the entire horizontal zone and / or parts of a pseudo-horizontal wellbore. They create a uniform depression or repression along the perforated area on both sides in the oil zone, respectively, in the casing of production or injection wells. They have horizontal and / or pseudo-horizontal shafts of production and injection wells under construction in parallel with each other, but across the predominant direction of fractures in the reservoir. Separately, the fraction of oil from gas condensate and gas is extracted from the reservoir and a volume of a thermochemically prepared liquid gas displacer, which is equal to the volume of liquid produced from it, is pumped into it with a volumetric rate that does not cause a fracturing of the reservoir in the oil zone, and the heated gas is pumped into it collector gas zone at a temperature above the reservoir.
