Description

A kind of electronic salvaging release of repetitive and salvaging method for releasing thereof
Technical field
The present invention relates to the auxiliary salvaging in a kind of down-hole/release integrated electric instrument, particularly relate to a kind of repetitive salvaging/method for releasing of Electronic control.
Background technology
The underground fishing tool of current use has a lot, and its main feature is rigidity fisher, and specificity is stronger, is only applicable to salvage, and can not realize release; And the release of aboveground application also can only carry out release can not realize salvage.
Traditional fisher, because deadweight is comparatively large, the instrument that easy impact failure is salvaged in salvaging process, weight is large, is inconvenient to go up terminated cable direct control, can not ensures the safety of the salvaged instrument in lower end.
For the operating feature of downhole stored pipe nipple, traditional release is inconvenient to operate, and release is complicated, and storage apparatus of being inconvenient to arrange in pairs or groups realizes sharp work.And some earth layer measuring instrument needs addressing to stop or release, can not realize repeating salvaging/release movement, the sharp work of this type of earth layer measuring instrument of can not arranging in pairs or groups.
For above-mentioned problems of the prior art, a kind of novel electromechanical integration repetitive salvaging/releasing device of research and design, thus the problem existing for overcoming in prior art is very necessary.
Summary of the invention
The object of this invention is to provide the electronic hole salvaging release tools of a kind of repetitive, power transmission shaft action is realized by the motion of Electric Machine Control screw pair, drive tightening sleeve moves back and forth, compress or unclamp claw structure, thus the salvaging/release movement realized repeatedly, coordinate the liquid level gauging sensor that release is installed, can judge that release arrives the position of down-hole, help operator to judge work opportunity.
Because this release uses electric operating, operation is simple and reliable, and reusable, so greatly simplify difficulty and the complexity of fishing, better improves operating efficiency.
The object of the invention is to be realized by following technical proposals.
The electronic salvaging release of a kind of repetitive, comprise connect successively from top to bottom top connection, transmission system, in establish the center tap of liquid level sensor, in establish the lower contact of click-on mechanism, be provided with in described transmission system by the reciprocator of Electric Machine Control, reciprocator's interlock click-on mechanism, realize release and the locking action of click-on mechanism, thus complete salvaging and dispose procedure.
Preferably, described reciprocator comprises the motor be located in transmission system, and motor output shaft is connected with feed screw nut pair, is connected with the power transmission shaft be connected with click-on mechanism under feed screw nut pair.
Preferably, described power transmission shaft extends in center tap cavity, is located bottom power transmission shaft by tightening sleeve, and power transmission shaft is provided with back-moving spring I, and back-moving spring I is spacing by tightening sleeve.
Preferably, described liquid level sensor is located at center tap and transmission system connection, for measuring the HTHP of liquid level.
Preferably, described click-on mechanism comprises four claws be distributed in lower contact cavity, each claw is connected on claw mount pad by pin, claw mount pad is provided with the claw compression contact that bottom extends into four claw lower ends, claw compresses contact upper end cover back-moving spring II, and back-moving spring II is located by end cap.
Preferably, described claw compresses contact and is applied in the through hole of end cap and claw mount pad, by the compression of back-moving spring and retracting spring power, claw is opened and closed.
Preferably, described lower contact cavity is set to the structure can holding fishing joint, and four claw interior shapes are corresponding with captured difform fishing joint.
Preferably, described fishing joint shaped upper part is ball-type, and the inner arc shape after four claws close up corresponds to ball-type.
Correspondingly, The present invention gives a kind of method that repetitive salvages release, comprise the steps:
1) instrument moves to above fishing joint, slowly toward declining, until the bulb partial insertion click-on mechanism of fishing joint, claw compresses contact moves and claw is drawn in automatically because of gravity, now fishing joint is free state, and claw is also in salvaging original state, does not lock;
2) driven by motor feed screw nut pair down end motion, back-moving spring I discharges, and makes clamping sleeve near click-on mechanism, until claw is pushed down by tightening sleeve completely; Now, fishing joint is pinned completely, and salvaging action completes;
3), after instrument and fishing joint are pinned, can draw with cable and deliver to addressing position;
4) driven by motor feed screw nut pair up end motion, power transmission shaft pulls clamping sleeve, make clamping sleeve away from click-on mechanism, until the claw in click-on mechanism is not subject to the pressure of clamping sleeve, the strength of back-moving spring II is released claw downwards and is compressed contact, make claw open further, the fishing joint now captured in claw inside discharges automatically by gravity.
Operation is simple and reliable in the present invention, and can reuse in the appointment moment, so greatly simplify difficulty and the complexity of fishing, better improves operating efficiency.
Feature of the present invention is:
1) the salvaging load that this salvaging release mates limits according to the pin shear stress in click-on mechanism, can realize only using less axial force (about 600N-1000N transmission system provides), the comparatively heavy load (49000N click-on mechanism provides) after locking can be realized, and salvage the load that load does not affect transmission system.
2) power of this salvaging release tightening sleeve locking state is determined by spring precompressed value completely, has nothing to do with leading screw and motor load, and now power transmission shaft is that free release conditions are only by environment stress.
3) when tightening sleeve performs release movement, motor needs the pressure overcoming spring, with the frictional force of sealing ring, therefore a release movement temporary duration, discharge complete rear motor and can automatically reset to the state of tightening up according to program, ensure that screw pair does not carry.
4) whole click-on mechanism is all outer is exposed in well fluid environment, do not consider that pressure changes, and the change of ambient temperature pressure makes conservation treatment for this release that affects of transmission system.
5) whole click-on mechanism can be changed by integral demounting, and convenient for maintaining cleans, and improves operating efficiency further.
6) upper loading limit of whole salvaging release is determined by cable, usually can not be used in the instrument that is hampered and salvage, use reliably safer in non-resistance instrument salvaging situation.
