Background technology
Hydraulic anchor in the packer is in the oilfield producing well, is used for preventing the downhole tool that tubing string moves up and down, and generally is made of hydraulic anchor body and the anchor fluke that is nested in wherein, and anchor fluke also claims " slips ".Be provided with pressing plate groove and spring eye in the anchor fluke, with spring bearer plate and bridge screw anchor fluke be pressed on the hydraulic anchor body after loading onto spring.During hydraulic anchor work, build the pressure in the oil pipe, anchor fluke is protruding under hydraulic action, and the wedging internal surface of sleeve pipe is realized the effect of grappling oil pipe; Behind the oil pipe internal and external pressure balance, anchor fluke is regained under the spring force effect, removes the grappling effect.
In the fracture in oil and water wells transformation process, after the anchor fluke of packer hydraulic anchor was constructed through fracture acidizing, its seal was out of shape easily, expands, and the anchor fluke cat's paw is also easy to wear.Therefore, anchor fluke and the cushion rubber that the anchor fluke of wearing and tearing be extracted and more renewed.But, the anchor fluke outside does not make things convenient for clamping or the parts that close, in the prior art, generally is the both sides of adopting spring bearer plate repeated action pressing plate groove, make anchor fluke left rotation and right rotation, loosening or compression in the hydraulic anchor body, extract or be pressed in the hydraulic anchor body by manpower again.Such method not only wastes time and energy, and simultaneously, anchor fluke cat's paw and cushion rubber easily cause damage.Therefore the scene needs a kind of anchor fluke and special-purpose dismantling device of easy disassembly.
Summary of the invention
The purpose of this utility model provides can pull out formula hydraulic anchor anchor fluke and puller and erecting tools, overcomes defective of the prior art, makes things convenient for maintenance and the maintenance of hydraulic anchor anchor fluke, increases work efficiency, and alleviates the labour intensity of maintenance work.
The utility model is achieved in that can pull out formula hydraulic anchor anchor fluke comprises the anchor fluke body, is provided with pressing plate groove and spring eye at the anchor fluke body, and spring eye is located at the middle part of pressing plate groove.Be provided with two semicircles in the spring eye both sides at pressing plate groove middle part and extract undercut, this semicircle is extracted undercut and the pressing plate groove connects and the head of extracting of puller is used.
The puller that can pull out formula hydraulic anchor anchor fluke comprises slip cap, sliding axle and extracts handle, and an end of sliding axle is to extract head, and the other end is provided with screw thread and extracts handle and be connected, and slip cap is set on the sliding axle; Extracting head is the strip shape body of two ends arc, and the pressing plate groove of the width of this strip shape body and anchor fluke body is with wide, and its thickness is extracted the height of undercut less than the semicircle that connects with the pressing plate groove, makes to extract can insert wherein.Slip slip cap bump is extracted handle, and impact is acted on the anchor fluke body by extracting head.
The erecting tools that can pull out formula hydraulic anchor anchor fluke comprises mounting handle and installing connecting rods, and installing connecting rods one end is mounting head, the other end and mounting handle welding; Mounting head is the strip shape body of two ends arc, and the pressing plate groove of the width of this strip shape body and anchor fluke body is with wide, and its thickness is greater than extracting the height of undercut with the semicircle of pressing plate groove perforation.The rotation mounting handle, mounting head can not screw in the semicircle of anchor fluke body and extract in the undercut, and revolving force is acted in the pressing plate groove, and the body rotation of drive anchor fluke also presses down, and anchor fluke and cushion rubber are pressed in the hydraulic anchor body.
The utility model compared with prior art has following useful effect.After the installation of packer hydraulic anchor can be pulled out formula hydraulic anchor anchor fluke, by special-purpose dismantling device, can extract and install easily, easily and quickly the hydraulic anchor anchor fluke.The special-purpose dismantling device of this hydraulic anchor anchor fluke is simple in structure, easy to operate, practical, safe and reliable, can effectively reduce the difficulty of maintaining packer work, shortens the maintenance time.Avoid simultaneously the damage to anchor fluke cat's paw and cushion rubber, time and manpower is saved greatly, improved work limitation, reduced cost of production.
