Abstract
The utility model relates to an oil pipe rubber anchoring device. The oil pipe rubber anchoring device mainly solves the problems that the existing oil pipe anchoring devices are easy to damage mineshafts and are easy to be jammed. The oil pipe rubber anchoring device is characterized in that the external thread of a central pipe (3) is connected with an anti-rotation body assembly (2), a liner pipe (5) which is provided with a rubber sleeve group (4) is sheathed outside the central pipe (3), and the anti-rotation body assembly (2) is contacted with the rubber sleeve group (4). The oil pipe rubber anchoring device does not damage the mineshafts and can not be jammed. The oil pipe rubber anchoring device has the advantages of simple structure and convenient using.
Description
Technical field:
The utility model relates to a kind of downhole tool used in the oil recovery field, oil field, belongs to a kind of oil pipe rubber anchoring device.
Background technology:
In the pumping production process, because fluid column load alternating action constantly is stretched oil pipe and shrinks on oil pipe and sucker rod when up-down stroke, pumping efficiency is low, and the oil pipe that works long hours also can cause fatigue damage; In order to address the above problem, prevent that oil pipe is flexible with load change in each stroke procedure, the application life that has so just reduced loss of plunger stroke and improved oil pipe normally the grappling of oil pipe afterbody.And present oil pipe anchoring device mainly is to adopt block teeth formula structure, utilization is squeezed in the purpose that reaches the grappling oil pipe on the pit shaft through the steel tooth after the Quenching Treatment, steel tooth wherein can make the pit shaft damage to the extruding of pit shaft, anchoring device uses for a long time in the down-hole and produces corrosion or cause deblocking ineffective because of amassing reasons such as sand incrustation, easily stuck and play not flowline, cause workover, bring loss to production.
The utility model content:
In order to overcome existing oil pipe anchoring device damage pit shaft and easily stuck deficiency, the utility model provides a kind of oil pipe rubber anchoring device, and this device does not damage pit shaft, can not produce stuck phenomenon yet, has characteristics simple in structure, easy to use.
The technical solution of the utility model is: a kind of oil pipe rubber anchoring device comprises top connection and the anti-assembly of turning, connection central tube under the top connection, the central tube external screw thread connects the anti-assembly of turning, and central tube is with the bushing pipe of band packing element group outward, and the anti-assembly of turning touches mutually with the packing element group.
Above-mentioned bushing pipe places under the top connection and with it and touches mutually, and the anti-assembly of turning connects seat tube by cutting part, and seat tube touches mutually with packing element group lower surface; Also the assembly of preventing turning can be placed under the top connection and with it and touch mutually, central tube connects seat tube by cutting part, and seat tube touches mutually with packing element group lower surface; In anti-turn assembly and structure that top connection is touched mutually, can be fixed with valve seat in the central tube, be equipped with valve ball on the valve seat.
The utlity model has following beneficial effect: owing to take such scheme, the central tube rotation drives anti-rotation body assembly and moves up and down, the center of rotation pipe can make the anti-assembly extruding packing element group of turning, thereby make packing element group distortion extruding pit shaft, utilize the frictional force of packing element group and pit shaft to reach the purpose of grappling oil pipe, neither damage pit shaft, can be because of the stuck not flowline that rises yet, simple in structure, easy to use.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is structure sectional views of another embodiment of the utility model.
1-top connection among the figure, the anti-assembly of turning of 2-, the 3-central tube, 4-packing element group, the 5-bushing pipe, 6-cuts part, 7-seat tube, 8-valve ball, 9-valve seat.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this device comprises top connection 1 and the anti-assembly 2 of turning, 1 time connection central tube 3 of top connection, central tube 3 external screw threads connect the anti-assembly 2 of turning, the central tube 3 outer bushing pipes 5 that are with band packing element group 4, bushing pipe 5 places top connection 1 time and touches mutually with it, and the anti-assembly 2 of turning connects seat tube 7 by cutting part 6, and seat tube 7 touches mutually with packing element group 4 lower surfaces.
As shown in Figure 2, also the assembly 2 of preventing turning can be placed top connection 1 time and touch mutually with it, central tube 3 connects seat tubes 7 by cutting part 6, and seat tube 7 touches mutually with packing element group 4 lower surfaces.Be fixed with valve seat 9 in the central tube 3, be equipped with valve ball 8 on the valve seat 9.Valve ball 8 forms ball-and-seat with valve seat 9, and the well-flushing water in the time of can stoping oil well heat to be washed flows downward and pours into oil reservoir, plays the effect of protection oil reservoir.
Above-mentioned in use dual mode is identical, all be that top connection 1 is connected under the tubing string afterbody center of rotation pipe 3 after the desired depth, so just can make the anti-assembly 2 of turning directly or by seat tube 7 push packing element groups 4, thereby make packing element group 4 distortion extruding pit shafts, utilize the packing element group 4 and the frictional force of pit shaft to reach the purpose of grappling oil pipe, neither damage pit shaft, can be because of the stuck not flowline that rises yet; During pump detection and workover, on carry central tube 3, it is disrumpent feelings to cut part 6, packing element group 4 times restores to the original state, and this device is tripped out smoothly, and is simple in structure, easy to use.
Claims (4)
1, a kind of oil pipe rubber anchoring device, comprise top connection (1) and the anti-assembly (2) of turning, top connection (1) is connection central tube (3) down, it is characterized in that: central tube (3) external screw thread connects the anti-assembly (2) of turning, the outer bushing pipe (5) that is with band packing element group (4) of central tube (3), the anti-assembly (2) of turning touches mutually with packing element group (4).
2, a kind of oil pipe rubber anchoring device according to claim 1, it is characterized in that: bushing pipe (5) places under the top connection (1) and touches mutually with it, the anti-assembly (2) of turning connects seat tube (7) by cutting part (6), and seat tube (7) touches mutually with packing element group (4) lower surface.
