Изобретение относится к нефтяной промышленности. Способ разработки месторождений вязких и битумных нефтей, в частности в пластах с малыми толщинами, включает эксплуатацию месторождений с помощью горизонтальных скважин. Для предотвращения преждевременного прорыва вытесняющего агента (пара, газа или растворителя) в добывающей скважине, проходящей в подошвенной части залежи, и повышения нефтеотдачи пласта увеличивается глубина выхода ствола добывающей скважины из-под продуктивного пласта, для создания своеобразного нефтяного затвора и для контроля за давлением в газовой подушке наружная обсадная колонна перфорируется в вертикальной части в районе кровли пласта, причем глубина жидкостного затвора зависит от свойств нефти ожидаемого дебита и пластового давления. Насосно-компрессорные трубы с насосом спускаются до нижней точки обсадной колонны, а нагнетательные скважины располагают параллельно добывающим, проводя горизонтальную часть в кровельной зоне пласта.The invention relates to the oil industry. The method of development of viscous and bituminous oil deposits, in particular in formations with small thicknesses, involves the exploitation of deposits using horizontal wells. To prevent premature breakthrough of the displacing agent (steam, gas or solvent) in the production well, passing in the bottom part of the reservoir, and increasing the oil recovery of the reservoir, the exit depth of the production well from the production reservoir increases gas cushion outer casing is perforated in the vertical part in the area of the roof of the reservoir, and the depth of the liquid gate depends on the properties of oil expected flow rate and about pressure. The tubing with the pump down to the lowest point of the casing, and the injection wells are located parallel to the production, conducting a horizontal part in the roof zone of the reservoir.
