Seal failure causes underground work to fail.And existing packer can not be finely divided the oil reservoir of different permeabilities layer note
Water, can not realize the stable high yield in oil field.
Utility model content
It is proposed in the above background technology to solve the purpose of this utility model is to provide a kind of gradually deblocking packer
Problem.
To achieve the above object, the utility model provides following technical solution：A kind of gradually deblocking packer, including center
Manage, be connected with the left of the central tube and set connector, ball seat, the outer wall of the central tube are connected with the right side of the central tube
Three packing elements are uniformly provided with from left to right, and each left and right sidewall of packing element and the junction of central tube are all provided with
There is rigidity spacer ring, be equipped with bidirectional anchor, packing main body on the central tube in each packing element successively from left to right
And eccentric injection mandrel, the cavity described in left end between packing element and central tube are the first water filling layer, every device glue described in middle-end
Cavity between cylinder and central tube is the second water filling layer, and the cavity described in right end between device packing element and central tube is the 3rd water filling
Layer.
Preferably, the diameter of the rigidity spacer ring is more than the diameter of central tube.
Preferably, the outer wall of the packing element is uniformly provided with groove.
Preferably, the outer wall for setting connector is equipped with external screw thread.
Preferably, the outer wall of the bidirectional anchor, packing main body and eccentric injection mandrel is equipped with anti-corrosion layer.
Preferably, a diameter of 150-170 millimeters of the packing element.
Compared with prior art, the beneficial effects of the utility model are：This gradually deblocking packer, wherein packing element
Good protecting effect, the rigidity of packing element left and right sidewall are played to bidirectional anchor, packing main body and eccentric injection mandrel
The setting of spacer ring, avoids when down-hole pressure is excessive, and during beyond the pressure-bearing limit of packing element, packing element is also easy to produce brokenly
The phenomenon of damage.Multiple packing main bodys are used in series, deblocking load is substantially reduced, ensures being smoothed out for job execution.It is left
Side seal is every the deblocking power of main body, and from the interference of right side packing main body deblocking power, and the deblocking power needed is small, so that each packing
Main body from left to right carries out gradually deblocking, efficiently reduces the difficulty of construction, accelerates the progress of construction, can be in oil-field flooding
Oil recovery field largely uses.
