The K344 expanding packer is an expanding fracturing packer which takes the expansion rubber sleeve as the sealing element, is packed by the hydraulic pressure difference, and is specially used for interlayer packing of the segmental fracturing. The matched compositions of the corresponding downhole tool and the expanding fracturing packer are used for segmental fracturing the construction process string, so as to finish the operation of dragging the multi-layer and multi-section fracturing of separate layers.
Packing: The oil pipe is added with hydraulic pressure, and the hydraulic pressure is functioned on the inner cavity of the rubber sleeve through the contact water holes below the packer. Due to the function of the pressure difference of the matched throttler, the rubber sleeve is expanded to be glued the casing. Therefore, the annular space of the oil sleeve is sealed.
Deblocking: after the pressure in the oil pipe is discharged, the pressure difference is disappeared, and the rubber sleeve is withdrawn by the elasticity.
