Description
Известный способ временной изол ции пластов обладает некоторой сложностью, заключающейс в необходимости производить работы по замораживанию части интервала продуктивного пласта.The known method of temporarily isolating formations has some difficulty, namely, the need to perform work on freezing part of the interval of the productive formation.
Предлагаемый способ не имеет этого недостатка, так как, с целью временной изол ции пласта, в скважине образуют песчаные пробкиперекрывающие нижележащие пласты. Частным случаем применени предлагаемого способа может быть поинтервальный гидроразрыв пласта.The proposed method does not have this drawback, since, in order to temporarily isolate the formation, sand plugs form in the wellbore overlapping the underlying formations. A particular case of the application of the proposed method may be interval fracturing.
Сущность применени этого способа заключаетс в том, что вначале производ т гидроразрЫБ нижнего горизонта при установке пакера между нижним и верхним горизонтами. Затем в скважине образуют песчаную почти непроницаемую пробку, перекрывающую нижний горизонт и, установив пакер выше верхнего горизонта, производ т гидроразрыв последнего .The essence of the application of this method lies in the fact that at first the hydraulic horizons of the lower horizon are produced when the packer is installed between the lower and upper horizons. Then a sandy almost impenetrable plug is formed in the well, which overlaps the lower horizon and, setting the packer above the upper horizon, fracturing of the latter is performed.
Таким же способом производ т гидроразрыв многопластового месторождени или гидроразрыв одного пласта.The same method is used to fracture a multilayer field or hydraulic fracturing of a single formation.
Предмет изобретени Subject invention
Способ изол ции пластов по авт. св. № 120806, отличающийс тем, что, с целью временной изол ции пласта, в скважине образуют песчаные пробки, перекрывающие нижележащие пласты.The method of seam isolation according to ed. St. No. 120806, characterized in that, in order to temporarily isolate the formation, sand plugs form in the well, overlying the underlying formations.
