Abstract
The invention discloses a detection method of an ejecting angle of an ejecting arm on a water injection instrument. The ejecting arm on the water injection instrument is hinged with a shell body through a hinge pin, one end of the ejecting arm is connected with an eccentric shaft in a contact mode, and an opening angle of the ejecting arm is controlled through rotation of the eccentric shaft. According to the detection method, a permanent magnet is arranged on the eccentric shaft, the eccentric shaft rotates and drives the permanent magnet to rotate synchronously, and the ejecting angle of the ejecting arm can be confirmed by a rotating angle of the permanent magnet. Through the simple method, the opening angle of the ejecting arm on the water injection instrument under the shaft can be detected directly on the ground, blind adjustment in the prior art is avoided, and the shortcoming of repeated test modification through feelings is overcome. According to the detection method, work efficiency is improved, work stability of the water injection instrument under the shaft is guaranteed, usage performance of the water injection instrument is improved, and good application effect is achieved.
Description
Technical field
The present invention relates to eject detection method and the device that arm ejects angle on a kind of water filling instrument, belong to the subsurface equipment technical field of structures.
Background technology
Oilfield exploitation is after the later stage, and general the employing to the mode of stratum water filling or polymer flooding guarantees crude production rate.Therefore the exploitation of water filling instrument is an important process.The water filling instrument need to be supported on the workbench of down-hole by ejecting arm when underground work, ejects the ejection angle of arm and has determined the stability of water filling instrument in the down-hole, and present three type water-quantity regulating devices used are without regulating arm opening angle measuring ability.Due to the water filling instrument in underground work, ground operating personnel can't see the open configuration that ejects arm on the water filling instrument, can only regulate with feeling, whether then transfer instrument sensation instrument is supported on workbench, if sensation does not support, just regulate again, sometimes need repeated multiple timesly just can be supported on workbench.Work efficiency is extremely low, and the stability of instrument is also poor.
Summary of the invention
The object of the invention is to, provide and eject detection method and the device that arm ejects angle on a kind of water filling instrument.Can in the aboveground ejection angle that judges accurately ejection arm on the water filling instrument, improve the water filling instrument at the job stability of down-hole, to overcome the deficiencies in the prior art.
Technical scheme of the present invention:
Eject the detection method that arm ejects angle on the water filling instrument, the ejection arm on the water filling instrument is hinged through bearing pin and housing, ejects arm one end and is connected with the excentric shaft contact, controls by the rotation of excentric shaft the opening angle that ejects arm; The method is to be provided with permanent magnet on excentric shaft, and excentric shaft rotarily drives the permanent magnet synchronous rotary, determines to eject the ejection angle of arm by the anglec of rotation of permanent magnet.
In preceding method, described permanent magnet is arranged on the height point correspondence position of excentric shaft or the low spot correspondence position of excentric shaft, the magnetic field intensity inductor is set near permanent magnet, magnetic field intensity strengthens when permanent magnet rotates near the magnetic field intensity inductor, when permanent magnet rotation during away from the magnetic field intensity inductor magnetic field intensity weaken, the magnetic field intensity that detects by the magnetic field intensity inductor determines to eject the opening angle of arm.
In preceding method, described magnetic field intensity inductor converts magnetic field intensity signal to voltage signal, and voltage signal is connected with ground computing machine through wire, demonstrates intuitively on computers the opening angle that ejects arm on the water filling instrument.
Eject angle detection device according to ejecting arm on the water filling instrument of preceding method formation, comprise the excentric shaft that is connected with the ejection arm contact, excentric shaft is provided with permanent magnet, is provided with the magnetic field intensity inductor near permanent magnet, and the magnetic field intensity inductor is connected with the computing machine on ground through wire.
Aforementioned ejection arm ejects in angle detection device, and described permanent magnet is arranged on the height point correspondence position of excentric shaft or the low spot correspondence position of excentric shaft.
Compared with prior art, the present invention is by simple method, and the ejection arm of direct-detection to the water filling instrument at the opening angle of down-hole, solves prior art and blindly regulate on the ground, by the sensation examination defective of transferring repeatedly.Both improve work efficiency, guaranteed again the job stability of water filling instrument in the down-hole.Make water filling instrument usability more perfect, obtained good effect.
