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

Hydraulic packer

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.
