Background
The packer is a downhole tool which is connected to a downhole string and used for packing an annular space between an oil pipe and an oil and gas well casing or an open hole well wall, when the annular space between the oil pipe and the oil and gas well casing or the open hole well wall needs to be packed, the packer is connected to the downhole string, and after the annular space is packed to a designed depth, a packing part on the packer is expanded to pack the annular space between the oil casing and the annular space through hydraulic driving and other modes. Different types of packers have different modes of activation and unsealing. After the hydraulic expansion type packer is lowered to the designed depth, pressurization is carried out in an oil pipe, high-pressure liquid acts on the inner cavity of the rubber sleeve through a pressure transmission pore in the packer, and the rubber sleeve expands to seal the annular space of the oil sleeve under the action of throttling pressure difference. When the oil pressure is released and the pressure of the oil sleeve is balanced, the rubber sleeve contracts to return to the original shape by the resilience force of the rubber sleeve to realize unsealing. After the compression packer is arranged to the designed depth, the compression packer pressurizes from the inside of the oil pipe, high-pressure liquid acts on the piston mechanism through a pressure transmission pore inside the packer, and the compression rubber sleeve expands to seal the annular space of the oil sleeve under the action of throttling pressure difference. When the oil pressure is released and the pressure of the oil sleeve is balanced, the rubber sleeve is restored to the original state by the resilience force of the rubber sleeve, and the rubber sleeve is unsealed.
