Abstract
The utility model discloses an integrative packer for metal spiral sealing and anchoring with long service life. The integrative packer is characterized in that a fixed threaded bushing, a one-stage spiral memory steel bar, a separated sliding sleeve, a second-stage spiral memory steel bar and a fixed connector penetrate through a central tube in sequence; a spiral convex guiding groove is formedin the fixed threaded bushing; a spiral concave guiding groove is formed on the peripheral surface of the central pipe corresponding to the fixed threaded bushing; one end of the one-stage spiral memory steel bar is fixed with the fixed threaded bushing; the other end of the one-stage spiral memory steel bar is fixed on one side of the separated sliding sleeve; the other side of the separated sliding sleeve is fixed at the end of the second-stage spiral memory steel bar; the other end of the second-stage spiral memory steel bar is fixed with the fixed connector; a straight convex guiding groove is formed in the separated sliding sleeve; a straight concave guiding groove is formed on the peripheral surface of the central section of the central tube; concave grooves and convex grooves are formed on two sides of the one-stage spiral memory steel bar and two sides of the second-stage spiral memory steel bar in an equidistant spacing manner; and the concave groove and the convex groove of the adjacent spiral bars are matched with each other. The concave groove and the convex groove of the adjacent spiral bars in the spiral memory steel bars are matched, so as to ensure stable anchoring.
Description
Technical field
The utility model relates to the oil well rig field, more particularly, relates to a kind of metal spiral sealing grappling one packer that is used for petroleum production engineering and underground work.
Background technology
The downhole packer that uses has many kinds at present, mainly form by parts such as top connection, central tube and sealed colloids, for example current version is a Y341 class packer, there is easily aging problem in its critical piece rubber tube, rubber tube uses the back loss of elasticity for a long time, cause and to withdraw, the problem of bit freezing occurs, had a strong impact on result of use.
The utility model content
Technical problem to be solved in the utility model is that overcoming current version is the deficiency that Y341 class packer exists, and a kind of metal spiral sealing grappling one packer of long service life is provided.
The utility model metal spiral sealing grappling one packer is achieved by following technical proposals, and retaining thread cover, one-level spiral memory steel bar, separation sliding sleeve, deuterostrophies memory steel bar and anchor tip pass central tube successively; In the retaining thread cover spiral prominence guide groove is set, overlaps corresponding central tube outer peripheral face with retaining thread the recessed guide groove of spiral is set, one-level spiral memory steel bar one end is fixed in the retaining thread cover, and the one-level spiral memory steel bar other end is fixed in separates sliding sleeve one side; Separate a fixedly end of deuterostrophies memory steel bar of sliding sleeve opposite side, the other end of deuterostrophies memory steel bar is fixed in anchor tip; In the separation sliding sleeve straight protruding guide groove is set, central tube middle part outer peripheral face is provided with straight recessed guide groove; The both sides of described one-level spiral memory steel bar and deuterostrophies memory steel bar are equidistant is provided with groove and tongue, and the groove of adjacent spiral bar matches with tongue.
The utility model can effectively be saved casing space, and spiral memory steel bar has high temperature resistant and characteristics high pressure, makes the utility model can high temperature resistant and high pressure, effectively increases the service life.The grappling that matches with tongue of the groove of the adjacent spiral bar of spiral memory steel bar is stablized in the utility model.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A sectional view (spiral memory steel bar cross section).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, retaining thread cover 3, one-level spiral memory steel bar 2, separation sliding sleeve 1, deuterostrophies memory steel bar 4 and anchor tip 5 pass central tube successively; In the retaining thread cover spiral prominence guide groove is set, overlaps corresponding central tube outer peripheral face with retaining thread the recessed guide groove of spiral is set, one-level spiral memory steel bar one end is fixed in the retaining thread cover, and the one-level spiral memory steel bar other end is fixed in separates sliding sleeve one side; Separate a fixedly end of deuterostrophies memory steel bar of sliding sleeve opposite side, the other end of deuterostrophies memory steel bar is fixed in anchor tip; In the separation sliding sleeve straight protruding guide groove is set, central tube middle part outer peripheral face is provided with straight recessed guide groove; The both sides of described one-level spiral memory steel bar and deuterostrophies memory steel bar are equidistant is provided with groove and tongue (as shown in Figure 2), and the groove of adjacent spiral bar matches with tongue.
The utility model operating principle is as follows: piston can promote the retaining thread cover when suppressing, the retaining thread cover is to the counter-rotation of spiral memory steel bar, the steel bar of spiral memory simultaneously is squeezed, the groove of adjacent spiral bar matches with tongue, and expansion step by step, the sealing sword can embed sleeve pipe and carries out grappling when spiral memory steel bar is expanded to maximum, and the mutual crush seal of spiral memory steel bar forms a shuttle shape.Identical during deblocking with original structure, to carry on directly, pin disconnects, and spiral memory steel bar can restore to the original state automatically.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
