Abstract
The utility model discloses an oil pipe centralizer for cable under protective well, it includes: right assembly and fixing bolt, wherein right the assembly and make by rubber materials, and be provided with the opening and be located the opening part vulcanize have with fixing bolt complex fixation nut. The utility model discloses can avoid tubular column and the direct friction of sheathed tube in the pit, cable, sensing line prevent the damage of cable, sensing line under effective protective well.
Description
Technical field
The utility model relates to a kind of tubing centrilizer for the protection of downhole cable.
Background technology
Water supply well is the well for exploiting groundwater and Drilling, and in water supply well, downhole submersible pumps cable and sense line are all outer with in submersible pump lower going-into-well at oil pipe.The vibrations of downhole cable and sense line or play friction in lower tubular column process between oil pipe and sleeve pipe, collision, all may cause the damage of cable, sense line, lead to down-hole accident and economic loss.
Utility model content
For above deficiency, the purpose of this utility model is a kind of tubing centrilizer for the protection of downhole cable of design, can avoid the direct friction of down-hole string and sleeve pipe, available protecting downhole cable, sense line, prevent the damage of cable, sense line.
The technical solution of the utility model is: a kind of tubing centrilizer for the protection of downhole cable; it comprises: righting assembly and set bolt; described righting assembly is made up of elastomeric material, and is provided with opening and is positioned at opening part sulfuration and have the hold-down nut coordinated with set bolt.
On the basis of technique scheme, comprise following attached technical scheme further:
Described righting assembly is hollow cylinder, and has some different radiis inside it and incomplete deep-slotted chip breaker.
The outside of described righting assembly is circumferentially longitudinally evenly distributed with several centering edges reducing to rub with internal surface of sleeve pipe, and arranged outside has the chamfering for conveniently making tubing string normally remove.
Have center cavity in described righting assembly, and deep-slotted chip breaker is connected with center cavity.
The cross section of described righting assembly for the circle that disconnects by opening, and set bolt is connected with hold-down nut through this opening.
Described opening is connected with center cavity.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
(1) make cable, sense line and tubing string be close to, the weight of suspended cables, prevent the vibrations of cable, sense line; (2) effective righting is carried out to water supply well tubing string, avoid the collision between oil pipe and sleeve pipe, avoid cable, sense line is squeezed and rubs; (3) can reuse.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structure chart of the present utility model, its broken section;
Fig. 2 is lateral view of the present utility model.
Detailed description of the invention
Embodiment: with reference to shown in Fig. 1-2, the utility model provides a kind of specific embodiment of the tubing centrilizer for the protection of downhole cable, and it comprises: the set bolt 2 inside having the righting assembly 1 of center cavity, be connected with righting assembly 1.Wherein righting assembly 1 be provided be positioned at outside several centering edges 3, be positioned at inner side and several deep-slotted chip breakers 4 be connected with center cavity and the hold-down nut 5 be connected with set bolt 2.Righting assembly 1 is roughly cylindrical and make for rubber, and cross section is off and disconnected circle, and set bolt 2 is connected with the opening of hold-down nut 5 by this disconnection, and hold-down nut 5 forms in opening part sulfuration.The size of this deep-slotted chip breaker 4 is different, and cable, sense line can pass from corresponding deep-slotted chip breaker 4.During use; being broken into two with one's hands by righting assembly 1 is placed on water supply well tubing string; be placed in the deep-slotted chip breaker 4 of corresponding diameter by needing the cable of protection and strain; tighten set bolt 2 and hold-down nut 5; righting assembly 1 and cable is made to be fixed on tubing string; because incomplete deep-slotted chip breaker designs, make the mode of electric cable protector appropriate cable more flexible, the cable size of adaptation is more extensive.After tripping out tubing string, if tubing centrilizer is without obviously distortion and damage in the utility model, just reusable.
The utility model compared with prior art has following advantages:
(1) make cable, sense line and tubing string be close to, the weight of suspended cables, prevent the vibrations of cable, sense line; (2) effective righting is carried out to water supply well tubing string, avoid the collision between oil pipe and sleeve pipe, avoid cable, sense line is squeezed and rubs; (3) can reuse.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
