Abstract

Разветвление можно изолировать от давления гидроразрыва с применением хвостовика, проходящего из основного ствола через разветвление в боковой ствол, при этом, по меньшей мере, участок хвостовика может извлекаться из бокового ствола перед завершением строительства скважины. Разветвление можно временно изолировать от высокого давления, например высокого давления в процессе гидроразрыва пласта для интенсификации притока. Часть хвостовика может извлекаться с применением отсоединяющего механизма или соответствующей методики.The branching can be isolated from hydraulic fracturing pressure using a liner passing from the main bore through a branching into the lateral bore, at least a portion of the liner may be removed from the lateral bore before completion of the well construction. The branching can be temporarily isolated from high pressure, for example high pressure during hydraulic fracturing to stimulate the flow. A portion of the shank may be removed using a release mechanism or appropriate technique.
