Abstract
The utility model relates to an oil well drilling and production technology field especially relates to a bidirectional bearing packer, include an outer sour jujube section of thick bamboo, top connection, center tube, packing element, packing element seat, go up cone, urceolus, slips, lower cone and lower clutch, the lower part of top connection with the upper portion threaded connection of center tube, the upper portion of an outer sour jujube section of thick bamboo, the lower part of an outer sour jujube section of thick bamboo with the upper portion cooperation of packing element, the lower part of packing element with the upper portion cooperation of packing element seat, it inserts to go up the upper portion of cone in the packing element seat, the lower part of going up the cone with the upper portion cooperation of slips, the lower part of slips with the upper portion cooperation of cone down, outer barrel casing is in on the slips and with the cone is connected down, down the cone the lower part with the upper portion cooperation of lower clutch. When an outer sour jujube section of thick bamboo pushed down, the cone downstream was gone up in the packing element shrink, props up the slips, realizes doing the card, and the packing element seat seals simultaneously. Can realize reliable sealing, the ratchet meshing realizes that reliable seat seals.
Description
Technical field
The utility model is related to oilfield drilling and production technology field, more particularly to a kind of Bidirectional bearing packer.
Background technology
Oil well casing causes sleeve pipe leakage phenomena occur because of reasons such as cementing quality, connection screw thread, ground movement, corrosions,
Oil supply well measure construction brings unfavorable factor and affects crude output.Once leakage situation occurs in the non-payzone of oil well, implementing to repair
Leakage points are must determine before multiple, the method for now verifying casing leakage point typically adopts Bidirectional bearing packer, in payzone with top
Position closing oil jacket annular space, is verified by sleeve pipe pressuring method to sleeve pipe.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 to judge leak position
Problem.
Such as：Slip-type Bidirectional bearing packer：Because slip-type Bidirectional bearing packer puts tubing string by above putting, transition card
Watt track back seat card forms fulcrum, setting using release tubing string suspending weight compression packing element, but this kind of Bidirectional bearing packer is not suitable for
The position construction shallower and deeper away from well head of checking leakage points, it is deep because tubing string suspending weight deficiency causes setting bad when shallow-layer is constructed
Because slips contrail is difficult during layer construction, cause setting difficulty.Particularly the problems referred to above are outstanding in horizontal well and high angle hole
For protrusion.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of Bidirectional bearing packer, is suitable for
It is setting in shallow-layer, it is setting easy.
The utility model for achieving the above object, is employed the following technical solutions：A kind of Bidirectional bearing packer, its feature exists
In：Including outer spine cylinder, top connection, central tube, packing element, glue tube base, upper cone, outer tube, slips, lower cone and lower contact；Institute
The bottom for stating top connection is threadedly coupled with the top of the central tube, and the top of the outer spine cylinder is slided with the top connection and matched somebody with somebody
Close, the outer middle part of spine cylinder and the relevant position of central tube are respectively equipped with the ratchet for cooperating, under the outer spine cylinder
Portion coordinates with the top of the packing element, and the bottom of the packing element coordinates with the top of the glue tube base, the top of the upper cone
In being inserted into the glue tube base, the top of the bottom of the upper cone and the slips coordinates, the bottom of the slips with it is described
The top of lower cone coordinates, and the outer sleeve is connected on the slips and with the lower cone, and circular hole, card are carried in outer sleeve
Watt stretch out from the circular hole, the bottom of the lower cone coordinates with the top of the lower contact.
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 utility model are:When outer spine cylinder is pushed, packing element shrinks upper cone and moves downward, and props up slips,
Card is made in realization, while packing element is setting.Reliable sealing can be realized, upper lower contact uses cast iron materials, facilitates drilling.Ratchet is ratcheting
Realize reliable setting.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is working state schematic representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1 and Fig. 2 institutes
Show, 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 tube
7th, slips 8, lower cone 9 and lower contact 10；The bottom of the top connection is threadedly coupled with the top of the central tube, described outer
The top of spine cylinder is slidably matched with the top connection, and the outer middle part of spine cylinder and the relevant position of central tube are respectively equipped with phase
The ratchet for mutually coordinating, ratchet can block in outer spine cylinder and central tube, and the bottom of the outer spine cylinder is matched somebody with somebody with the top of the packing element
Close, that is, the bottom of outer spine cylinder withstands on the top of packing element, the bottom of the packing element coordinates with the top of the glue tube base, also
It is that the bottom of packing element is withstood on glue tube base, the top of the upper cone is inserted in the glue tube base, the bottom of the upper cone
Coordinate with the top of the slips, specifically, the upper and lower surfaces of the slips are taper surface, and with upper cone and lower cone on
Contact surface coordinate.The top of the bottom of the slips and the lower cone coordinates, the outer sleeve on the slips and with
Lower cone connection, carries circular hole in outer sleeve, slips stretches out from the circular hole, the bottom of the lower cone with it is described under connect
The top of head coordinates.
When outer spine cylinder is pushed, packing element shrinks upper cone and moves downward, and props up slips, and card is made in realization, while packing element is setting.Energy
Reliable sealing is realized, upper lower contact uses cast iron materials, facilitates drilling.Ratchet is ratcheting to realize that reliability is setting.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
