Claims (1)

Предлагаются способ и средства для предупреждения разжижения или перемещения пакового гравия в промышленных скважинах для добычи текучей среды, которое может возникнуть в результате повышения давления жидкости, вызванного закупоркой скважины или иными всплесками давления. Клапан перепада давления, выполненный в виде запорного клапана, предусмотрен в трубе ниже паккера, расположенного вокруг трубы и над верхом пакового гравия. Запорный клапан устанавливается в закрытом положении под действием, например, пружины, которое меньше, чем давление, вызывающее передвижение или разжижение гравиевого пака. Всплеск давления такого, как закупорка скважины или снижение скорости потока, увеличивает давление в трубе, которое вынуждает клапан открываться, вследствие чего давление в паке гравия срабатывается до уровня ниже критического.A method and means are provided for preventing liquefaction or movement of packaged gravel in industrial wells to produce fluid that may result from an increase in fluid pressure caused by blockage of the well or other pressure surges. The differential pressure valve, made in the form of a shut-off valve, is provided in the pipe below the packer located around the pipe and above the top of the pack of gravel. The shut-off valve is installed in the closed position under the influence of, for example, a spring that is less than the pressure causing movement or liquefaction of the gravel pack. A burst of pressure such as a blockage in the well or a decrease in flow rate increases the pressure in the pipe, which forces the valve to open, resulting in pressure in the gravel pack being triggered to a level below critical.
