Abstract
The utility model relates to a tool for achieving the feed-in/pull-out of an oil layer protection valve. The tool is characterized in that the tool comprises a tool body made of a metal material, a connection box formed at one end of the tool body, a connection key and a shearing pin hole formed in the axial direction on the circumference of the tool body for the purpose of being connected with the oil layer protection valve, and a seal ring groove and a clamp spring groove formed in sequence in the position adjacent to the other end of the tool body; and an optional clamp spring can be arranged inside the clamp spring groove. The utility model is characterized in that the utility model is a combination of a feed-in tool and a pull-out tool during the well completion operation and production at an oil field, that is, the utility model can not only feed the oil layer protection valve in a well, but also pull the oil layer protection valve out of the well after being equipped with the clamp spring. In addition, the tool has the advantages of simple structure and design, convenient operation, low manufacturing cost and the like.
Description
Technical field
The utility model belongs to the oilfield well completion technical field, relate to particularly that a kind of oilfield well completion work production uses simple in structure, be convenient to operate and safe and reliable oil layer protection valve is sent into/the recovery instrument.
Background technology
In present known completion practice, the oil layer protection valve sends into/and the recovery instrument comprises hydraulic pressure and two kinds of delivery modes of machinery.For the hydraulic setting instrument, hydraulic channel is generally arranged, piston and ratchet structure, following behind the setting position, pitching, pressurization sets; For mechanical setting tool, when needing to discharge, generally, free behind the upper lifting pipe string by transferring tubing string weight and making running tool go to the off-position to anticlockwise.Above-mentioned two kinds of instruments can only be sent into and setting tool generally speaking, and can't realize the function of the instrument that trips out and complex structure.
Summary of the invention
The utility model for solve that the technical problem that exists in the known technology provides that a kind of oilfield well completion work production uses simple in structure, be convenient to operate and safe and reliable oil layer protection valve is sent into/the recovery instrument.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the oil layer protection valve is sent into/the recovery instrument; it is characterized in that: comprise tool body by metal material system; tool body one end is shaped on the connection box; on the circumference of tool body is axial, be shaped on the moment of torsion that is used for being connected and transmit key and shear pin hole with the oil layer protection valve; be shaped on seal groove and jump ring groove successively near tool body other end position, removable jump ring is housed in the jump ring groove.
The utility model can also adopt following technical scheme:
Be evenly distributed with moment of torsion on described tool body circumference is axial and transmit key, it is pyramidal structure that moment of torsion transmits the key end, and makes integrative-structure with tool body.
It is the Long Circle pin hole that described tool body circumference is axially gone up equally distributed shear pin hole.
Advantage and the good effect that the utlity model has are: but the utility model the oilfield well completion work production be lowered to removal process in direct circulation or anti-circulation, rotatable transfer torque.When needs are lowered to the oil layer protection valve, described sending into/recovery instrument (not selecting the spring that is installed) is connected with the oil layer protection valve, be lowered to drilling rod (or oil pipe) and send into/the recovery instrument, the back that puts in place presses down by gravity and cuts off shear pin and realize slipping out of the hand.Because the utility model adopts technique scheme; when needs reclaim the oil reservoir protective valve; the sending into of oil layer protection valve/recovery instrument outside is put jump ring (reclaim and must select the spring that is installed); be lowered to drilling rod (or oil pipe) and send into/the recovery instrument; to send into/recovery instrument insertion oil layer protection valve; transmit key by moment of torsion simultaneously and apply moment of torsion being recovered instrument; and be recovered the oil layer protection valve and apply upper lifting force by the jump ring lock hanging; the grappling that top packer inserts sealing is removed in rotation, and the upper lifting pipe post realizes reclaiming the oil reservoir protective valve then.The utility model integrates and is lowered to and the recovery instrument, can be lowered to the oil layer protection valve, and choosing is adorned a jump ring and can be realized that again the oil layer protection valve reclaims out well.In addition this instrument also have structure design simple, be convenient to advantages such as operation and cost of manufacture are low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is A-A sectional view of Fig. 1.
Among the figure: 1, connect box; 2, tool body; 3, moment of torsion transmits key; 4, shear pin hole; 5, jump ring groove; 6, seal groove.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2; the oil layer protection valve is sent into/the recovery instrument; comprise tool body 2 by metal material system; tool body one end is shaped on and connects box 1; evenly be shaped on axially at the circumference of tool body and be used for the connecting key 3 and the shear pin hole 4 that are connected with the oil layer protection valve; be shaped on seal groove 6 and a jump ring groove 5 successively near tool body other end position, removable jump ring is housed in the jump ring groove.Described seal groove and the inwall mating reaction of oil layer protection valve upper end can realize being connected the back sealing with the oil layer protection valve, are convenient to circulation and pressure testing.Do not select the spring that is installed in the jump ring groove when this instrument is used as running tool, select the spring that is installed as the recovery instrument time, the jump ring groove fit effect with the oil layer protection valve upper end that is recovered can apply upper lifting force to the oil layer protection valve.
Operating principle of the present utility model is:
The oil layer protection valve is sent into/the recovery instrument inserts upper shield along the keyway of upper shield the inside, press down then and send into/the recovery instrument, until send into/recovery instrument and the shear pin hole above the upper shield overlap, insert shear pin (shearing force is as required set the quantity of shear pin) will send into from the shear pin hole/recovery instrument and upper shield couple together, at the oil layer protection valve and send into/recovery instrument two termination pressure testing plugs carry out pressure testing and detect, confirm that sealing is qualified, last 1 cylindrical drill bar (or oil pipe) inserts sealing with the grappling formula below the oil layer protection valve assembly and inserts cyclic flusher packer top before the sand control top packer; To insert sealing and insert in the top packer, and close the preventer annulus test and require qualifiedly, check that the insert head sealing is intact to satisfying the operator.Press down 3-5 tons of shearings and send into/shear pin between recovery instrument and the oil layer protection valve upper shield, the instrument of removing and trip out ground of slipping out of the hand.When needing to reclaim the oil reservoir protective valve; the sending into of oil layer protection valve/recovery instrument outside is put jump ring; be lowered to drilling rod (or oil pipe) and send into/the recovery instrument; to send into/recovery instrument insertion oil layer protection valve; the grappling that top packer inserts sealing is removed in rotation; upper lifting pipe post is then sent into/is reclaimed instrument lower end jump ring and locks automatically in the recovery jump ring groove above the upper shield, continues the upper lifting pipe post and can reclaim out well to the oil layer protection valve.
