Изобретение относится к нефтегазодобывающей промышленности, а именно к устройствам для разобщения ствола скважины при проведении в ней различных технологических операций, в том числе связанных с изменением температуры закачиваемых рабочих агентов. Технический результат заключается в повышении надежности работы пакера, облегчения его снятия и подъема. Пакер содержит ствол, на котором установлен посадочный шлипсовый узел и уплотнительный элемент с гидроприводом, имеющим фиксатор положения поршня. Новым является то, что пакер снабжен дополнительным посадочным шлипсовым узлом, установленным на стволе, к которому крепится цилиндр гидропривода уплотнительного элемента, а шток поршня этого гидропривода выполнен в виде патрубка, взаимосвязанного с уплотнительным элементом.The invention relates to the oil and gas industry, and in particular to devices for separating a wellbore during various technological operations, including those associated with a change in temperature of injected working agents. The technical result consists in increasing the reliability of the packer, facilitating its removal and lifting. The packer contains a barrel on which a landing slips assembly and a sealing element with a hydraulic actuator having a piston position lock are installed. What is new is that the packer is equipped with an additional landing slip assembly mounted on the barrel to which the cylinder of the hydraulic actuator of the sealing element is attached, and the piston rod of this hydraulic actuator is made in the form of a pipe interconnected with the sealing element.
