Description
Известен способ увеличени приемистости нагнетательных скважин путем многократных кратковременных изливов, чередующихс с короткими остановками дл восстановлени забойного давлени .There is a method of increasing the injectivity of injection wells by means of multiple short spouts alternating with short stops to restore the bottomhole pressure.
Отличительной особенностью предлагаемого способа вл етс то, что дренаж призабойной зоны производ т путем чередовани закачки воды в скважилу и излива с противодавлением на устье при поддержании на забое давлени , повышенного по сравнению с гидростатическим . При работе по предложенному способу улучшаетс очистка призабойной зоны вследствие более полного извлечени загр зн юпдего материала из полостей треш,ин при их пребывании в открытом состо нии в услови х.A distinctive feature of the proposed method is that the bottomhole zone drainage is performed by alternating water injection into the well and spout with back pressure at the mouth while maintaining pressure at the bottomhole that is higher than hydrostatic. When working by the proposed method, the cleaning of the bottomhole zone is improved due to more complete removal of the contaminated material from the trash cavities, in case of their being in the open state under conditions.
когда забойное давление превышает гидростатическое .when bottomhole pressure exceeds hydrostatic.
Жидкость дл восстановлени давлени в пласте закачиваетс через затрубное пространство скважины, изливаетс через насосно-компрессорные трубы.The fluid to restore the pressure in the reservoir is pumped through the annulus of the well, poured out through the tubing.
Предмет изобретени Subject invention
Способ увеличени приемистости нагнетательных скважин, отличающийс тем, что, с целью лучшей очистки призабойной зоны пласта , производ т дренаж призабойной зоны путем чередовани закачки воды в скважину и излива с противодавлением на устье при поддержании на забое давлени , повышенного по сравнению с гидростатическим.A method for increasing the injectivity of injection wells, characterized in that, in order to better clean the bottomhole formation zone, the bottomhole zone is drained by alternating water injection into the well and spout with backpressure at the wellhead while maintaining pressure at the bottom hole that is higher than hydrostatic.
