Abstract

Изобретение относится к нефтедобыче и позволяет извлечь из пласта вязкую нефть путем термовоздействия на пласт. Нефтедобывающая скважина включает направленную вверх или по существу горизонтальную впускную секцию так, что создается скважина в форме буквы J или L. В область впускной секции нагнетают горячую текучую среду в виде пара так, что нагнетаемая горячая текучая среда течет вместе с добытой сырой нефтью в скважину, нагревая таким образом впускную секцию скважины и стимулируя поток сырой нефти в впускную секцию и через нее.The invention relates to oil production and allows you to extract from the reservoir viscous oil by thermal action on the reservoir. The oil well includes an upward or substantially horizontal inlet section so that a J or L well is created. In the region of the inlet section, hot fluid is injected in the form of steam so that the injected hot fluid flows with the extracted crude oil thus heating the inlet section of the well and stimulating the flow of crude oil into and through the inlet section.
