Abstract
Изобретение относится к области разработки неоднородных по геолого-физическим свойствам изолированных литологически или тектонически экранированных многопластовых нефтенасыщенных залежей (линз), вскрытых одиночной скважиной. Обеспечивает максимальный коэффициент извлечения нефти и накопленную добычу нефти при уменьшении периода разработки. Способ разработки изолированной литологически или тектонически экранированной неоднородной нефтенасыщенной залежи, вскрытой одиночной вертикальной скважиной, расположенной в центральной или краевой зоне залежи, включает определение зоны выклинивания или тектонического экранирования залежи и анализ профиля залежи, бурение не менее одного бокового ствола через вертикальную скважину с входом в нефтенасыщенную залежь на расстоянии не менее 50 м от вертикального ствола в зону с наибольшими извлекаемыми запасами и вскрытие верхнего нефтенасыщенного пропласта залежи, перфорацию в вертикальной скважине в интервале нефтенасыщенной залежи, установку по меньшей мере одного пакера выше зоны перфорации, закачку рабочего агента в залежь и отбор пластового флюида. Согласно изобретению боковой ствол строят с субвертикальным окончанием, которым вскрывают нефтенасыщенные пропластки, из ствола вертикальной скважины и субвертикального окончания бокового ствола путем их перфорирования и создания не менее чем на одном уровне глубокопроникающих радиальных каналов фильтрации в каждом пропластке формируют по меньшей мере одну ориентированную по дирекционному углу систему охвата залежи выработкой (систему вытеснения и систему сбора пластового флюида).The invention relates to the development of heterogeneous in geological and physical properties of isolated lithologically or tectonically shielded multilayer oil-saturated deposits (lenses) opened by a single well. Provides maximum oil recovery and cumulative oil production while reducing development time. A method for developing an isolated lithologically or tectonically shielded inhomogeneous oil-saturated reservoir, opened with a single vertical well located in the central or marginal zone of the reservoir, includes determining a pinch zone or tectonic screening of the reservoir and analyzing the profile of the reservoir, drilling at least one lateral well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance into the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil well through the vertical well with the entrance to the oil in the oil well. reservoir at a distance of at least 50 m from the vertical shaft to the zone with the largest recoverable reserves and the opening of the upper oilfield enasyschennogo proplasta deposits perforations in a vertical well in the range of oil-saturated reservoir, setting at least one packer above the perforations, injecting a working fluid reservoir and the reservoir fluid selection. According to the invention, the lateral stem is built with a subvertical ending, which opens oil-saturated streaks, from the vertical well bore and the subvertical end of the lateral trunk by perforating them and creating at least one level of deep-penetrating radial filtration channels in each interlayer forming at least one oriented along the directional angle reservoir coverage system (displacement system and formation fluid collection system).
