Abstract
The utility model discloses a wing structure of a centering device. The two ends of the wing structure are connected with a testing instrument. The wing structure of the centering device comprises a centering device wing base body and a centering device rubber body arranged on the outer wall of the centering device wing base body, wherein the centering device rubber body and the centering device wing base body are integrated. A groove is formed in the centering device wing base body. The centering device rubber body comprises a rubber cylinder and a wing panel arranged on the rubber cylinder; the rubber cylinder is arranged in the position of the groove of the centering device wing base body through glue. The diameter of the centering device wing structure is the same as the diameter of the testing instrument, drilling fluid is prevented from producing eddy currents when the drilling fluid flows through a wing of the centering device via the surface of the instrument, the requirement of the wing of the centering device for anti-scouring performance is met, and the service life of the wing of the centering device is prolonged.
Description
Technical field
The utility model relates to drilling equipment, particularly a kind of centralizer wing structure.
Background technology
After the downhole data that wireless drilling measurer records is decoded by ground control box, via the Computer display data, and offer the driller operative employee by driller's display very first time, and show the important project data such as drilling tool attitude and formation parameter, instruct driller workman to carry out the work.
The structural representation of the centralizer wing that Fig. 1 is prior art, the maximum cylindrical of the centralizer wing 2 ' the diameter H of place is greater than tester 1 outside diameter K, therefore, easily produces eddy current when drilling fluid flows through the instrumentation table surface current through centralizer wing place, thereby the cutting centralizer wing, cause serious washing away.
The utility model content
The purpose of this utility model is to provide a kind of centralizer wing structure, the diameter of this centralizer wing structure is identical with the tester diameter, prevent that drilling fluid from flowing through the instrumentation table surface current and producing eddy current when centralizer wing place, meet the requirement of the scour resistance of the centralizer wing, improve the application life of the centralizer wing.
In order to realize above purpose, the utility model is achieved through the following technical solutions:
A kind of centralizer wing structure, its two ends are connected with tester, are characterized in, comprise: centralizer wing matrix, be arranged on the centralizer rubber bodies on centralizer wing matrix outer wall;
Described centralizer rubber bodies and centralizer wing matrix are integral type.
Described centralizer wing matrix is provided with groove.
Described centralizer rubber bodies comprises the rubber cylindrical shell and is arranged on the fin on the rubber cylindrical shell; Described rubber cylindrical shell glue is built in centralizer wing groove of substrate position.
The external circular diameter of described rubber tube is identical with centralizer wing matrix outside diameter, makes rubber cylindrical shell and centralizer wing matrix form complete cylinder.
The external circle of described rubber tube and centralizer wing matrix cylindrical are identical with the tester outside diameter.
The utility model compared with prior art, has the following advantages:
The utility model due to the external circle of rubber tube and centralizer wing matrix cylindrical identical with the tester outside diameter, prevent that drilling fluid from flowing through the instrumentation table surface current and producing eddy current when centralizer wing place, meet the requirement of the scour resistance of the centralizer wing, improve the application life of the centralizer wing.
The accompanying drawing explanation
The structural representation that Fig. 1 is prior art centralizer wing structure;
The sectional view that Fig. 2 is a kind of centralizer wing structure of the utility model;
The lateral view that Fig. 3 is a kind of centralizer wing structure of the utility model;
The application schematic diagram that Fig. 4 is a kind of centralizer wing structure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 2,3, 4, a kind of centralizer wing structure, its two ends are connected with tester 1, and this structure comprises: centralizer wing matrix 2, be arranged on the centralizer rubber bodies on centralizer wing matrix 2 outer walls; Described centralizer rubber bodies and centralizer wing matrix 2 are integral type.Described centralizer wing matrix 2 is provided with groove.
Described centralizer rubber bodies comprises rubber cylindrical shell 31 and is arranged on the fin 32 on rubber cylindrical shell 31; Described rubber cylindrical shell 31 glue are built at centralizer wing matrix 2 groove location places.The external circular diameter D of rubber tube is identical with centralizer wing matrix outside diameter A, makes rubber cylindrical shell 31 and centralizer wing matrix 2 form complete cylinder.Described rubber cylindrical shell 31 cylindricals and centralizer wing matrix 2 cylindricals are identical with tester 1 outside diameter.
As shown in Figure 4, during use, the centralizer wing structure is linked into to tester 1, drilling fluid flows through from top to bottom from the annular space zone between non magnetic drill collar 4 internal diameters and tester 1 outer wall, tester 1 surface is caused and washed away, due to rubber cylindrical shell 31 cylindricals and centralizer wing matrix 2 cylindricals identical with tester 1 outside diameter, drilling fluid process centralizer wing structure is without any obstruction, fin 32 is smooth surface simultaneously, and, not as the hole of installation hold-down screw of the prior art, avoid producing eddy current.
In sum, a kind of centralizer wing structure of the utility model, the diameter of this centralizer wing structure is identical with the tester diameter, prevents that drilling fluid from flowing through the instrumentation table surface current and producing eddy current when centralizer wing place, meet the requirement of the scour resistance of the centralizer wing, improve the application life of the centralizer wing.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
