The invention relates to the field of
oil field thickened oil
recovery equipment, in particular to a double-packer
steam injection integrated device and method for
oil field thickened oil
recovery. According to the technical scheme, the lower end of an upper packer is connected with a lower packer through an interlayer spacing
pipe and a connecting core
pipe, and a setting device and a one-way oil extraction device are installed at the lower end of a
steam injection valve; a releasing core
pipe is installed in an inner cavity of the upper packer, the lower end of the releasing core pipe is connected with an interlayer spacing pipe, a connecting core pipe and a compensation core pipe, the lower end of the compensation core pipe penetrates through the lower packer to be connected to a setting
steam injection plug, a setting device is arranged on the lower side of a ball seat, and the setting device is fixedly connected to an inner cavity of a shell of the steam injection valve through a locking anchoring force pin. The device has the beneficial effects that the device is tripped into a well at a time, so that the setting of two oil
layers is reliable, the loss of injected substances and energy during steam injection is avoided, the steam injection efficiency is improved, meanwhile, the
corrosion to an
oil well sleeve is reduced, and the service life of an
oil well is prolonged; and the construction procedures are reduced, the labor intensity of workers is reduced, and the construction period is shortened.
