By adopting the tool, the hydraulic anchor volume tube can be easily, conveniently and quickly pulled out, time and labor are greatly saved and damage of the tool accessories is avoided.
Description
Technical field
The present invention relates to a kind of draw-off gear, specifically is a kind of puller of hydraulic anchor volume pipe.
Background technology
Hydraulic anchor is in the field produces well, is used for preventing the downhole tool that tubing string moves up and down from generally being made up of volume pipe and the anchor fluke that is nested in wherein, and inside, volume pipe bottom is marked with liquid, pressurising, and the volume pipe mouth of pipe is provided with the pressing plate that compresses anchor fluke.In hydraulic anchor when work, build the pressure in the volume pipe, anchor fluke under the effect of fluid pressure, protruding, the chucking internal surface of sleeve pipe is realized the grappling action; After volume pipe internal pressure balance, anchor fluke is regained under the elastic force effect of baffle plate inner spring, removes the grappling effect.
The volume pipe of hydraulic anchor on the RTTS packer is passing through the construction of sand fracturing and acid fracturing, and volume pipe possibility slight deformation accumulates the mud sediment thing easily in the volume pipe, make the volume pipe clamp live, be difficult to extract.In the prior art, generally be adopt pipe wrench repeatedly the action volume inside pipe wall, it is rotated up and down, treat the loosening back of volume pipe, extract through manpower again.Because smooth surface, the no step of volume pipe are stressed thereby pipe wrench is had no way of, and make the volume pipe be difficult to be pulled out; Simultaneously, such method of pulling out can cause in various degree and must bite and damage the volume tube body, consuming time again, consumption power.For example: maintain a volume pipe and need about 4 hours consuming time.
Summary of the invention
The objective of the invention is:
Provide a kind of under petroleum gas reservoir reconstruction condition the maintaining instrument of used RTTS packer, specifically be the puller of hydraulic anchor volume pipe.
The technical scheme that the present invention adopted is:
A kind of hydraulic anchor volume pipe puller, said puller comprises axle, slide block, overcoat and locking device, slide block is connected with axle one end; The outside of overcoat cooperates installation with volume pipe inboard; 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 is in the track outer end, and said locking device is the stopping means of the relative position between slide block and the overcoat.
Said volume pipe inboard is a periphery; Overcoat comprises several flap slips sheet and terminal pads thereof; Terminal pad one end connects flap slips sheet, the other end connects axle; Said slide block is a bullet, and the medial surface of flap slips sheet is that inner conical surface, the lateral surface of corresponding bullet side face is the periphery of corresponding volume inside pipe wall.
Said flap slips sheet evenly distributes, is symmetricly set on the outer rim of terminal pad.
On the said flap 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 present invention produced is:
After adopting the present invention's " a kind of hydraulic anchor volume pipe puller ", can be easily, easily and fast extract hydraulic anchor volume pipe.This hydraulic anchor volume pipe 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.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cross section partial enlarged drawing of Fig. 1;
Label is represented among the figure: 1-slide block, 2-flap slips sheet, 3-overcoat, 4-gravity drop hammer, 5-axle, 6-locking nut.
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 present invention is the puller of this hydraulic anchor volume pipe, and this puller comprises axle 5, slide block 1, overcoat 3, locking device and external force bringing device, and its effect end is the inwall of volume pipe.The outside of overcoat 3 cooperates installation, set inside that a slide block 1 is arranged with the volume inside pipe wall, 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 is in the track outer end.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 the volume pipe.
Because said volume pipe inboard is a periphery, overcoat 3 comprises several flap slips sheet 2 and terminal pads thereof, and terminal pad one end connects flap slips sheet 2, the other end connects axle 5.Slide block 1 is a bullet, and flap slips sheet 2 is arranged between the male cone (strobilus masculinus) and volume inside pipe wall of slide block 1, and its medial surface is that inner conical surface, the lateral surface of corresponding slide block 1 male cone (strobilus masculinus) is the periphery of corresponding volume inside pipe wall.Flap slips sheet 2 evenly distributes, is symmetricly set on the outer rim of terminal pad, between have the space, this specific embodiment adopts 4 lobe flap slips sheets 2.The both sides of flap slips sheet 2 all adopt sliding the wiping to cooperate, and promptly flap 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 volume inside pipe wall.In addition, be to ensure the sliding intensity that cooperates of wiping, on the lateral surface of flap slips sheet 2, axially be provided with wave-formed mouth along axle 5, and, because.Flap 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, be provided with external screw thread on the axle 5 vertically, 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.
Method for using of the present invention is: flap slips sheet 2 is inserted in the hydraulic anchor volume pipe; 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, make that the wave-formed mouth on the flap slips sheet 2 expands; Make it bite the volume inside pipe wall effectively with radial load that 360 directions produce, 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 on the hydraulic anchor volume inside pipe wall, loosening volume pipe.
