In the APR testing tool, the outer wall of RTTS packer is provided with several hydraulic anchors, the circular hole, the close installation that are provided with on the anchor fluke outer wall applying sleeve outer wall, the outer face of anchor fluke be provided with one along end face radially, run through the square groove of anchor fluke both sides.To the petroleum gas reservoir reconstruction time, on this RTTS packer the anchor fluke of hydraulic anchor through the construction of sand fracturing and acid fracturing after, its seal easy deformation, expansion, therefore, the anchor fluke that the anchor fluke that wear and tear is extracted, more renewed.But the anchor fluke outside does not make things convenient for clamping or the parts that close, and has only the square groove can be stressed.In the prior art, generally be to adopt locking pliers to act on the both sides of the square groove of anchor fluke outer end repeatedly, make anchor fluke left rotation and right rotation, loosening in circular hole, extract through manpower again.The method of pulling out so not only wastes time and energy, also fragile puller and workpiece.For example: maintain an extended type hydraulic anchor (12 anchor flukes) and need 3-4 consuming time hour, and damage one of locking pliers, simultaneously, the groove face of anchor fluke outer end square groove is prone to cause damage.
Summary of the invention
The maintaining instrument of RTTS packer specifically is the puller of hydraulic anchor anchor fluke after a kind of petroleum gas reservoir reconstruction is provided, in the APR testing tool.
The technical scheme that the utility model adopted is:
A kind of hydraulic anchor anchor fluke puller; This hydraulic anchor anchor fluke outer face is provided with a square groove, and said puller comprises axle, slide block, overcoat and locking device, and slide block is connected with axle one end; The outside of overcoat cooperates installation with square groove on the anchor fluke; Slide block is arranged on overcoat inside, is provided with track axial along axle, that supply slide block to slide in the overcoat, and the contact surface of track and slide block is intilted inclined-plane; The initial position of slide block in the track outer end, corresponding square groove bottom position, said locking device is the stopping means of the relative position between slide block and the overcoat.
Square groove on the said anchor fluke is a groove that runs through anchor fluke both sides, three structures; Corresponding with it; Overcoat also adopts three structures; Comprise two positioned opposite the slips sheet and with the link of axle, said slide block is a prismatoid, the medial surface of slips sheet is that interior inclined-plane, the lateral surface on inclined-plane, corresponding prismatoid both sides is the plane of the straight wall of corresponding anchor fluke square groove.
On the said slips sheet outer surface, axially be provided with wave-formed mouth along axle.
Said slide block and track contact surface are provided with the spacing shoulder that cooperatively interacts.
Be provided with external screw thread on the said axle vertically, locking device is to cooperate the locking nut of installing with external screw thread.
Said axle is provided with along the gravity drop hammer of axle axial action.
The beneficial effect that the utility model produced is:
After adopting the utility model " a kind of hydraulic anchor anchor fluke puller ", can be easily, easily and fast extract the hydraulic anchor anchor fluke.This hydraulic anchor anchor fluke puller is simple in structure; Use simple, easy to operate, very practicality, safe and reliable, can effectively reduce, shorten maintenance period the difficulty in this packer maintenance; Avoid damage simultaneously to metal fittings; Improved work limitation, tool fitting and personnel are difficult for damaging, time and manpower is saved greatly.

Label is represented among the figure: 1-slide block, 2-slips sheet, 3-overcoat, 4-gravity drop hammer, 5-axle, 6-locking nut, 7-square groove.
The specific embodiment
Like Fig. 1, shown in Figure 2; In the APR testing tool; The outer wall of RTTS packer is provided with several hydraulic anchors, the circular hole, the close installation that are provided with on the anchor fluke outer wall applying sleeve outer wall, the outer face of anchor fluke be provided with one along end face radially, run through the square groove 7 of anchor fluke both sides.
The utility model is a kind of hydraulic anchor anchor fluke puller, and the effect end of this hydraulic anchor anchor fluke puller is the square groove 7 on the anchor fluke outer face, and this puller comprises axle 5, slide block 1, overcoat 3, locking device and external force bringing device.The outside of overcoat 3 cooperates installation, set inside that a slide block 1 is arranged with square groove 7 on the anchor fluke, and this slide block 1 connects an end of axle 5.Be provided with in the overcoat 3 along axle 5 axially, the track that supplies slide block 1 to slide, the contact surface of this track and slide block 1 is intilted inclined-plane, the initial position of slide block 1 in the track outer end, the position of corresponding square groove 7 bottom surfaces.Simultaneously, also be provided with locking device and external force bringing device on the puller, locking device is the stopping means of the relative position between slide block 1 and the overcoat 3, and the external force bringing device is the stressing device that external force acts on the puller, extracts for anchor fluke.
Because the square groove 7 on the anchor fluke is grooves that run through anchor fluke both sides, three structures, corresponding with it, overcoat 3 also adopts three structures, comprise two positioned opposite slips sheet 2 and with the link of axle 5.Slide block 1 is a prismatoid; Two sidewalls of its corresponding square groove 7 in two inclined-planes; Slips sheet 2 is arranged between the inclined-plane and square groove 7 sidewalls of slide block 1, and its medial surface is that interior inclined-plane, the lateral surface on inclined-plane, corresponding prismatoid both sides is the plane of corresponding anchor fluke square groove 7 straight walls.Slips sheet 2 both sides all adopt sliding the wiping to cooperate, and promptly slips sheet 2 medial surfaces cooperate with sliding wiping the in slide block 1 inclined-plane, and lateral surface cooperates with also sliding wiping of square groove 7 straight walls.In addition, be to ensure the sliding intensity that cooperates of wiping, on the lateral surface of slips sheet 2, axially be provided with wave-formed mouth along axle 5; Slips sheet 2 medial surfaces and slide block 1 inclined-plane are provided with the spacing shoulder that cooperatively interacts, as the stopping means of the relative position between slide block 1 and the overcoat 3.
Simultaneously, the other end of axle 5 axially is provided with external screw thread along axle 5, and the locking device of axle 5 is to cooperate the locking nut of installing 6 with external screw thread.
In addition, axial along axle 5, on axle 5, also be provided with gravity drop hammer 4.
The method for using of the utility model is: slips sheet 2 is inserted in the square groove 7 of anchor fluke; Turn locking nut 6; Make axle 5 under the effect of external screw thread and locking nut 6, move right, slide to the right in orbit thereby drive slide block 1, to slide into spacing shoulder place stuck when slide block 1.At this moment, clash into gravity drop hammer 4 axially, to the right along axle 5 again, make axle 5 that jarring campaign to the right is delivered in the anchor fluke square groove 7, loosening anchor fluke.
