Abstract
The invention discloses a plate type centering device with a controllable outer diameter and a manufacturing method of the plate type centering device. A main body of the plate type centering device is manufactured into a split structure, namely the main body of the plate type centering device consists an upper main body and a lower main body, two ends of a centering plate are respectively connected onto the upper main body and the lower main body, the upper main body and the lower main are separated away or close to each other so as to lead the centering plate to deform, and accordingly the outer diameter of the plate type centering device is controlled or adjusted. The plate type centering device is simple in structure. The main body is the split structure and consists of the upper main body and the lower main body which are movable connected, the upper main body and the lower main body are separated away or close to each other so as to lead the centering plate to deform, and accordingly the outer diameter of the plate type centering device is adjustable. Abrasion of the centering plate is avoided, the service life of the plate type centering device is long, and simultaneously, underground work effect is ensured. In addition, connection of a combined structure consisting of a motor and a transmission shaft is realized, movement stability of the upper main body and the lower main body is guaranteed, and service reliability of the plate type centering device is improved. Due to the advantages, the plate type centering device is favorable for large-range popularization.
Description
Technical field
The invention belongs to oil field downhole instrument technical field, particularly a kind of controlled outside dimension chip centralizer and preparation method thereof.
Background technology
At present, tester is carried out when going into the well work in the oil field, adopts centralizer more.The chip centralizer is comparatively use always a kind of, and its function of setting upright is realized by body resistance-strengthening tablets.The outside dimension of traditional chip centralizer is unadjustable.If the external diameter of chip centralizer is less, it is bad then to set upright effect; If the external diameter of chip centralizer is bigger, then in the process of going into the well, the body resistance-strengthening tablets easy abrasion, thus cause the chip centralizer to be unfavorable for using.These drawbacks limit the popularization on a large scale of chip centralizer.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of simple in structure, and the outside dimension scalable, result of use is better, the life-span is longer, is beneficial to controlled outside dimension chip centralizer of popularization and preparation method thereof, to overcome the deficiency of prior art.
The present invention constitutes like this: the preparation method of a kind of controlled outside dimension chip centralizer of the present invention is; The body making of chip centralizer is become split type structure; The body making that is about to the chip centralizer is made up of last main body and following main body; And the two ends of body resistance-strengthening tablets are connected on main body and the following main body separating or, can make the controlled or adjusting of outside dimension of chip centralizer like this through last main body and following main body near making body resistance-strengthening tablets deformation.
Of the present invention a kind of controlled outside dimension chip centralizer according to the said method structure; Comprise main body and the following main body that is connected with last subject activity; Side in last main body and following main body is respectively equipped with upper spring and lower spring; Between upper spring and lower spring two ends, be respectively equipped with slip ring and downslide rotating ring, between last slip ring and downslide rotating ring, be connected with body resistance-strengthening tablets.
In the above-mentioned controlled outside dimension chip centralizer, the described main body that goes up is to be in transmission connection with power transmission shaft that is connected with motor and following main body screw thread through motor provided thereon.
In the aforesaid controlled outside dimension chip centralizer, be provided with sealing ring 10 at the joint that descends main body 2 outsides with last main body 1.
Owing to adopted technique scheme, compare with prior art, structure of the present invention is comparatively simple.The split-type structural that it adopts upper and lower subject activity to connect, through upper and lower body portion from or near making body resistance-strengthening tablets deformation, make outside dimension scalable of the present invention.Avoided the wearing and tearing of body resistance-strengthening tablets, application life is longer; Simultaneously, guaranteed work in the down-hole.In addition, the present invention adopts the combining structure of motor and power transmission shaft to be connected, and has guaranteed the stationarity of upper and lower main body motion, has improved the reliability that the present invention uses.Owing to possess above-mentioned advantage, the present invention helps promoting the use of on a large scale.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The last main body of being labeled as of accompanying drawing: 1-, main body under the 2-, 3-upper spring, 4-lower spring, the last slip ring of 5-, 6-downslide rotating ring, 7-body resistance-strengthening tablets, 8-motor, 9-power transmission shaft, 10-sealing ring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Embodiments of the invention: the present invention improves to form on the basis of existing chip centralizer; The preparation method of a kind of controlled outside dimension chip centralizer of the present invention is; The single agent structure transformation of the way of existing chip centralizer is made split type structure; The body making that is about to the chip centralizer is made up of last main body and following main body; And the two ends of its body resistance-strengthening tablets are connected on main body and the following main body separating or, can make the controlled or adjusting of outside dimension of chip centralizer like this through last main body and following main body near making body resistance-strengthening tablets deformation.
The structural representation of the of the present invention a kind of controlled outside dimension chip centralizer that makes up according to method of the present invention is as shown in Figure 1; This controlled outside dimension chip centralizer comprises the structure that has the commercially available chip centralizer that is provided with the single main body structure now; The main body that it is single is changed system into the split-type structural of being made up of last main body 1 and following main body 2; Main body 2 under flexibly connecting on the last main body 1; Make it to separate or near motion, a upper spring 3 and lower spring 4 are installed respectively, install slip ring 5 and downslide rotating ring 6 respectively in the bottom of upper spring 3 and the upper end of lower spring 4 in the side of last main body 1 and following main body 2; To go up slip ring 5 and be socketed in respectively on main body 1 and the following main body 2, body resistance-strengthening tablets 7 will be installed between last slip ring 5 and downslide rotating ring 6 with downslide rotating ring 6; In order to guarantee the stationarity of main body 1 and following main body 2 relative motions, improve the reliability that the present invention uses, can motor 8 be installed on last main body 1, on motor 8, connect power transmission shaft 9, will descend main body 2 to be connected again with power transmission shaft 9; In order to protect the present invention, improve application life, can with the joint of last main body 1 sealing ring 10 be installed in following main body 2 outsides.
Embodiment of the present invention is not limited to the foregoing description, and the various variations of under the prerequisite that does not break away from aim of the present invention, making all belong to protection scope of the present invention.
