Abstract
The utility model discloses an eccentric water injection well alignning arm structure, including instrument outer tube in the pit, be provided with the recess in the pit on the instrument outer tube, be provided with the alignning arm in the recess, the alignning arm is connected with instrument outer tube in the pit through the round pin, the recess with sell between be provided with the torsional spring, the one end of instrument outer tube is provided with the cam in the pit, cam and alignning arm contact, the utility model discloses alignning arm length has been shortened to shorten the distance between its and the regulating arm, improve the direction success rate, change to former pressure spring structure instead the torsional spring structure, the instrument structure is optimized more, and torsional spring life is longer, improves instrument direction claw life.
Description
Technical field
The utility model patent relates to a kind of guide grab structure, particularly a kind of eccentric water injection guide grab structure.
Background technology
At present, in oilfield development process, by special water injection well, water is injected oil reservoir, keep or recover formation pressure, oil reservoir is made to have stronger driving force, to improve exploitation rate and the recovery ratio of oil reservoir, water injection well leads and realizes that instrument docks with injection well downhole flow regulator in injection well downhole flow regulator is a key component, be directed to power and directly affect survey tune, and existing water injection well guide grab adopts stage clip structure, spring easily corrodes corrupted, life-span is short, guide grab length is longer, and impact is directed to power, so existing eccentric water injection guide grab structure is still perfect not.
Utility model content
The purpose of this utility model is: provide a kind of structure simple, safe and reliable, shorten guide grab length, thus the distance shortened between itself and regulating arm, improve a kind of eccentric water injection guide grab structure being directed to power, long service life, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of eccentric water injection guide grab structure, comprise downhole instrument outer tube, downhole instrument outer tube is provided with groove, guide grab is provided with in groove, guide grab is connected with downhole instrument outer tube by pin, between groove and pin, be provided with torsion spring, one end of downhole instrument outer tube is provided with cam, and cam contacts with guide grab.
Downhole instrument outer tube arranges the axle connecting cam.
Described cam is provided with high contact plane and low contact plane.
Owing to have employed technique scheme, compared with prior art, the utility model shortens guide grab length, thus shortens the distance between itself and regulating arm, improves and is directed to power; Use former stage clip structure instead torsion spring structure, apparatus structure is optimized more, torsion spring longer service life, improves the advantages such as instrument direction pawl application life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of cam;
Description of reference numerals: 1-downhole instrument outer tube, 2-groove, 3-guide grab, 4-sells, 5-torsion spring, 6-cam, 7-axle, 8-height contact plane, the low contact plane of 9-.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of eccentric water injection guide grab structure, comprise downhole instrument outer tube 1, downhole instrument outer tube 1 is provided with groove 2, guide grab 3 is provided with in groove 2, guide grab 3 is connected with downhole instrument outer tube 1 by pin 4, between groove 2 and pin 4, be provided with torsion spring 5, one end of downhole instrument outer tube 1 is provided with cam 6, cam 6 contacts with guide grab 3.
Downhole instrument outer tube 1 arranges the axle 7 connecting cam 6.
Described cam 6 is provided with high contact plane 8 and low contact plane 9.
During utility model works, downhole instrument outer tube 1 is milled with groove 2, groove 2 can hold guide grab 3 completely, and guide grab 3, torsion spring are fixed on downhole instrument outer tube 1 by pin 4, and guide grab 3 can rotate around pin 4.Cam 6 is milled with high contact plane 8 and low contact plane 9, can realize controlling guide grab 6 to flick or draw in, when instrument is transferred, cam 6 is in high contact plane 8 and controls guide grab 3 and draw in and be convenient to instrument and go into the well, after arriving down layer position, by on carry instrument, scrape cam 6 off, cam 6 is in low contact plane 9, guide grab 3 flicks under torsion spring 5 acts on, and guide grab 3 contacts with nib profile in injection well downhole flow regulator and realizes leading.
The utility model shortens guide grab length, thus shortens the distance between itself and regulating arm, improves and is directed to power; Use former stage clip structure instead torsion spring structure, apparatus structure is optimized more, torsion spring longer service life, improves instrument direction pawl application life.
