Abstract
The utility model provides a rotary type oil pipe anchor which comprises a central pipe (1), an anchor jaw seat (2), an anchor jaw (3), a return spring clamp (4), a special inner hexagon bolt (5), a centralizing body (6), a spring (7), a centralizing block (8), a gland bush (9) and an inner hexagon bolt (10), wherein all the parts are connected through buckles and sequentially connected for constituting the rotary type oil pipe anchor. The centralizing block plays a centralizing role during positive rotation of a pipe column, the central pipe is in a spiral shape, and the rotation of the central pipe can extrude the anchor jaw out of the anchor jaw seat and enable the anchor jaw to be embedded on the inner wall of a sleeve, so that an anchoring role is played and setting is further completed. Contrariwise, the rotary type oil pipe anchor can be unset by lifting the pipe column upwards. The rotary type oil pipe anchor can improve resistance to radial torque, unsetting load, hardness, corrosion resistance, durability and other performances, and prevent breaking and sand sticking.
Description
Technical field
The utility model relates to a kind of rotary tubing anchor.
Background technology
Rotary tubing anchor is an a kind of conventional anchoring device of using screw pump oil production well.General have radial load grappling effect down in the screw pump bottom, prevents because the stator rotation causes the problem of friction damage between stator and the rotor.Improved the life-span of screw pump widely.The patent No. is that 00211735.5 utility model patent discloses a kind of rotary oil pipe anchor; This anchor comprises top connection, central tube and lower contact; Carry out an anchor, disanchor through rotation mode, for further improving the performance of rotary tubing anchor, such as performances such as anti-radially moment of torsion, deblocking load, hardness, corrosion resistance, durabilities; And prevent disconnected to take off, the sand card, the utility model provides a kind of rotary tubing anchor.
The utility model content
The utility model purpose is to provide a kind of rotary tubing anchor; This rotary tubing anchor comprises: central tube 1, anchor fluke seat 2, anchor fluke 3, back-moving spring card 4, special hexagon socket head cap screw 5, centralizer body 6, spring 7, wiper block 8, gland 9, hexagon socket head cap screw 10; Said component are linked in sequence and form rotary tubing anchor all by buckle.
According to the rotary tubing anchor of the utility model, wherein, central tube is spiral-shaped, positive tube post, and wiper block plays centralizing function, and central tube rotates anchor fluke is extruded from the anchor fluke seat, is embedded on the internal surface of sleeve pipe, plays the effect of grappling, thereby accomplishes the seat envelope.
According to the rotary tubing anchor of the utility model, wherein, said rotary tubing anchor is through upper lifting pipe post deblocking.
The rotary tubing anchor of the utility model has improved such as performances such as anti-radially moment of torsion, deblocking load, hardness, corrosion resistance, durabilities, and prevent effectively disconnected to take off, the sand card.
Description of drawings
Fig. 1 is the vertical section structure sketch map according to the rotary tubing anchor of the utility model.
Fig. 2 is the cross-sectional structure sketch map according to the rotary tubing anchor of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Wherein, the Reference numeral implication is: 1---central tube; 2---the anchor fluke seat; 3---anchor fluke; 4---the back-moving spring card; 5---special hexagon socket head cap screw; 6---centralizer body; 7---spring; 8---wiper block; 9---gland; 10---hexagon socket head cap screw.
One, structural principle:
As shown in Figure 1, rotary tubing anchor comprises central tube 1, anchor fluke seat 2, anchor fluke 3, back-moving spring card 4, special hexagon socket head cap screw 5, centralizer body 6, spring 7, wiper block 8, gland 9, hexagon socket head cap screw 10.These component are linked in sequence and form rotary tubing anchor all by buckle.
As shown in Figure 2, positive tube post, wiper block plays centralizing function, and central tube is spiral-shaped, and central tube rotates anchor fluke is extruded from the anchor fluke seat, is embedded on the internal surface of sleeve pipe, plays the effect of grappling, thereby accomplishes the seat envelope, otherwise, realize deblocking.
Two, functional characteristics:
1, this instrument aims at the solution radial load and designs, novel structure, and the anti-rotation performance is high, and anti-radially moment of torsion is greater than 140kNm.
2, the deblocking load is little, and the upper lifting pipe post leans on tubing string rotation deblocking.
3, body and anchor fluke all adopt nitrogen treatment, and hardness is high, and is corrosion-resistant, good antiscale property.
4, this product is not disturbed by sand production, and anti-grittiness can be good.
5, repeatedly repeat block envelope, deblocking of this product, product is not fragile, and the durability period is long, but the majority repeated application.
Three, seat envelope principle:
Just changeing 45 ° of seat envelopes.
Four, deblocking principle:
Upper lifting pipe post deblocking (because of tubing string has not the moment of torsion of eliminating, during the upper lifting pipe post, tubing string is reverse rotation voluntarily, and is up with tubing string, deblocking automatically, on put forward deblocking power≤10KN).
Five, technical data:
The instrument model for this reason instrument at a kind of goods and materials code in oil field.
Six, construction sequence:
1, is lowered to sand anchor, tail pipe, tubing anchor, screw pump (stator) successively by design.
2,, just changeing oil pipe 5 ~ 8 circles (1500m well depth) with hydraulic tongs, seat sealed tube anchor down to the design well depth.
3, be lowered to have rotor rod string to design attitude.
4, extension is taken out.
Seven, typical wells
Because oil is thick, and sand content is big, often take place disconnectedly to take off, the sand card before high flat 52 wells are taken out and executed, the longest less than of pump detection period 2 months, be lowered to this tubing anchor after, prevented the wriggling and the rotation of tubing string effectively, both improved pump efficiency, protected screw pump and tubing string again.After the measure, pump detection period 18 months.This tubing anchor adds up 60 wells of constructing in the promotion oil recovery factory at present, seat envelope success rate 100%.
