Description
Technical field
The present invention relates to oilfield drilling and production technology field, more particularly to a kind of Bidirectional bearing packer.
Background technology
There is leakage phenomena in oil well casing casing caused by the reasons such as cementing quality, connection screw thread, ground movement, corrosion,
Unfavorable factor is brought to oil well measure construction and influences crude output.Once leakage situation occurs in the non-payzone of oil well, implementing to repair
Leakage points are must determine before multiple, now verify that the method for casing leakage point generally uses Bidirectional bearing packer, in payzone with top
Position closing oil jacket annular space, verifies casing by casing pressuring method.But existing a few money Bidirectional bearing packers are in reality
Apply and test in set work progress, have unfavorable factor in varying degrees, cause construction to have some setbacks, it is impossible to accurately judge leak position
Problem.
Such as：Slip-type Bidirectional bearing packer：Because slip-type Bidirectional bearing packer by above putting puts tubing string, transition card
Watt track back seat card forms fulcrum, and using discharging, tubing string suspending weight compression packing element is setting, but such a Bidirectional bearing packer is not suitable for
Verify the leakage points position construction shallower and deeper away from well head, it is setting bad caused by tubing string suspending weight deficiency when shallow-layer is constructed, it is deep
Because slips contrail is difficult during layer construction, cause setting difficulty.Particularly the above problem is outstanding in horizontal well and high angle hole
For protrusion.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and a kind of Bidirectional bearing packer is provided, suitable for shallow
Layer is setting, setting easy.
The present invention to achieve the above object, using following technical scheme：A kind of Bidirectional bearing packer, it is characterised in that：
Including outer spine cylinder, top connection, central tube, packing element, glue tube base, upper cone, outer barrel, slips, lower cone and lower contact；On described
The lower part of connector is threadedly coupled with the top of the central tube, and the top of the outer spine cylinder is slidably matched with the top connection, institute
State the middle part of outer spine cylinder and the relevant position of central tube and be respectively equipped with the ratchet of mutual cooperation, the lower part of the outer spine cylinder and institute
The top for stating packing element coordinates, and the lower part of the packing element and the top of the glue tube base coordinate, and the top of the upper cone is inserted into
In the glue tube base, the lower part of the upper cone and the top of the slips coordinate, the lower part of the slips and the lower cone
Top coordinate, the outer sleeve is connected on the slips and with the lower cone, carries circular hole in outer sleeve, slips from this
Stretched out in circular hole, the lower part of the lower cone and the top of the lower contact coordinate.
The upper and lower surfaces of the slips are taper surface, and are coordinated with the contact surface on upper cone and lower cone.
The beneficial effects of the invention are as follows:When outer spine cylinder pushes, packing element shrinks upper cone and moves downward, and props up slips, realizes
Card is made, while packing element is setting.It can realize reliable sealing, upper lower contact uses cast iron materials, facilitates drilling.The ratcheting realization of ratchet
It is reliable setting.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the working state schematic representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and the preferred embodiment embodiment that the present invention will be described in detail.As depicted in figs. 1 and 2,
A kind of Bidirectional bearing packer, including outer spine cylinder 1, top connection 2, central tube 3, packing element 4, glue tube base 5, upper cone 6, outer barrel 7, card
Watts 8, lower cone 9 and lower contact 10；The lower part of the top connection is threadedly coupled with the top of the central tube, the outer spine cylinder
Top be slidably matched with the top connection, the middle part of the outer spine cylinder and the relevant position of central tube are respectively equipped with phase interworking
The ratchet of conjunction, ratchet can block outer spine cylinder and central tube, and the lower part and the top of the packing element of the outer spine cylinder coordinate,
The lower part of exactly outer spine cylinder withstands on the top of packing element, and the lower part of the packing element and the top of the glue tube base coordinate, that is, glue
The lower part of cylinder is withstood on glue tube base, and the top of the upper cone is inserted into the glue tube base, the lower part of the upper cone and institute
The top for stating slips coordinates, specifically, the upper and lower surfaces of the slips are taper surface, and with connecing on upper cone and lower cone
Contacting surface coordinates.The top of the lower part of the slips and the lower cone coordinates, the outer sleeve on the slips and with it is described
Lower cone connects, and circular hole is carried in outer sleeve, and slips is stretched out from the circular hole, the lower part of the lower cone and the lower contact
Top coordinates.
When outer spine cylinder pushes, packing element shrinks upper cone and moves downward, and props up slips, card is made in realization, while packing element is setting.Energy
Realize reliable sealing, upper lower contact uses cast iron materials, facilitates drilling.The ratcheting realization of ratchet is reliable setting.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
