Abstract
The utility model relates to an oil well drilling and production technology field especially relates to a hydraulic packer, including top connection, center tube, anchor body, go up fluke, dog, down fluke, urceolus, piston, outer central tube, go up cone, packing element, cone, slip spider, slips, lower clutch down, the top connection with the center tube is connected, anchor body installs center tube upper portion, it places in respectively with lower fluke to go up the fluke among the anchor body, the outer central tube cover is in the center tube middle part, the lower part of piston with the epicone physical contact, the lower part of packing element with the down upper portion contact of cone, the lower part of lower cone with the contact of the upper portion of slip spider, the lower part of lower clutch with the lower part threaded connection of center tube. It is closely quick that the card is made to this device, and when the center tube was suppressed, liquid passed the space of center tube, through outer central tube, promotes the piston and move down. The piston pushing centrum moves down, the compression packing element, and simultaneously, the slip spider struts the slips, realizes doing the card.
Description
Technical field
This utility model is related to oilfield drilling and production technology field, more particularly to a kind of hydraulic 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 hydraulic packer, in payzone with upper bit envelope
Oil jacket annular space is closed, sleeve pipe is verified by sleeve pipe pressuring method.But existing a few money hydraulic packers are tested set and are applied in enforcement
During work, there is unfavorable factor in varying degrees, causes construction to have some setbacks, it is impossible to accurately judge leak position problem.
Such as:Slip type hydraulic packer:Because slip type hydraulic packer puts tubing string by above putting, behind conversion slips track
Seat card forms fulcrum, setting using release tubing string suspending weight compression packing element, but this kind of hydraulic packer be not suitable for verifying leakage points away from
The shallower and deeper position construction of well head, when shallow-layer is constructed, because tubing string suspending weight deficiency causes setting bad, because of card when deep layer is constructed
Watt contrail difficulty, causes setting difficulty.Particularly the problems referred to above are especially prominent in horizontal well and high angle hole.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of hydraulic packer, it is adaptable to shallow
Layer is setting, setting easy.
This utility model for achieving the above object, is employed the following technical solutions:A kind of hydraulic packer, it is characterised in that:
Including top connection, central canal, anchor body, upper anchor fluke, block, lower anchor fluke, outer tube, piston, exterior central tube, upper cone, packing element, under
Cone, slip spider, slips, lower contact;The top connection is connected with the central canal, and the anchor body is arranged on the central canal
Top, the upper anchor fluke and lower anchor fluke are respectively placed in the anchor body, fixed by the block between upper anchor fluke and lower anchor fluke
Position, the outer tube is connected with the bottom of the anchor body, and the exterior central tube is enclosed within the central canal middle part, and the piston is placed in
It is slidably matched between the outer tube and the exterior central tube and with the two, the central canal and exterior central tube are provided with and the work
The corresponding through hole in plug bottom, the bottom of the piston contacts with the upper cone, the bottom of the upper cone and the packing element
Upper contact, the upper contact of the bottom of the packing element and the lower cone, the bottom of the lower cone and the slip spider
Upper contact, the bottom of the slip spider coordinates with the slips, and the bottom of the slips connects with the top of the lower contact
Touch, the bottom of the lower contact is connected with the lower thread of the central canal.
The beneficial effects of the utility model are:This device makees card quickly closely, and when central canal is suppressed, liquid passes through center
The space of pipe, by exterior central tube, promotes piston to move down.Piston promotes vertebral body to move down, and compresses packing element, meanwhile, slip spider is strutted
Card is made in slips, realization.
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 hydraulic packer, including top connection 1, central canal 2, anchor body 3, upper anchor fluke 4, block 5, lower anchor fluke 6, outer tube 7, work
Plug 8, exterior central tube 9, upper cone 10, packing element 11, lower cone 12, slip spider 13, slips 14, lower contact 15;The top connection with
The central canal connection, the anchor body is arranged on the central canal top, and the upper anchor fluke and lower anchor fluke are respectively placed in described
In anchor body, positioned by the block between upper anchor fluke and lower anchor fluke, the outer tube is connected with the bottom of the anchor body, institute
State exterior central tube and be enclosed within the central canal middle part, the piston is placed between the outer tube and the exterior central tube and slides with the two
Dynamic to coordinate, the central canal and exterior central tube are provided with the through hole corresponding with the piston base, the bottom of the piston with
Upper cone contact, the upper contact of the bottom of the upper cone and the packing element, the bottom of the packing element and the lower cone
The upper contact of body, the upper contact of the bottom of the lower cone and the slip spider, the bottom of the slip spider and the card
Watt coordinate, the upper contact of the bottom of the slips and the lower contact, under the bottom of the lower contact and the central canal
Portion is threadedly coupled.
This device makees card quickly closely, and when central canal is suppressed, liquid passes through the space of central canal, by exterior central tube,
Piston is promoted to move down.Piston promotes vertebral body to move down, and compresses packing element, meanwhile, slip spider struts slips, and card is made in realization.
The above is only preferred implementation 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 this 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.
