[0031] An embodiment of the application provides a downhole health diagnosis disc of a rod pump, which comprises a main disc 100 and an auxiliary disc 200 connected in a coaxial rotation manner, as shown in the drawings. Figure 1 In implementation, the main disc 100 and the auxiliary disc 200 can be connected in a rotation manner through rivets 300, rotation shafts and the like. The main disc 100 and the auxiliary disc 200 have a small axial gap therebetween, so as to facilitate the rotation of the two.

The dynamometer diagram area 111 comprises a plurality of typical dynamometer diagrams, the dynamometer diagram classification area 112 comprises a plurality of dynamometer diagram categories, and the first analysis number area 113 comprises a plurality of analysis numbers. The dynamometer diagram area 111, the dynamometer diagram classification area 112 and the first analysis number area 113 are annular areas, and are sequentially and correspondingly arranged from outside to inside, that is, the three areas are concentric annular areas.

[0033] As shown in the drawings, Figure 3 The second main surface 120 of the main disc 100 is provided with a first dynamometer diagram analysis area 121, a second analysis number area 122 and a first measure number area 123.

[0037] In practice, the colors of the areas where the indicator diagram types are located can be changed at intervals, and the colors of the indicator diagram types and the corresponding indicator diagram areas are different, so that the area separation is obvious and easy to find.

[0038] In use, the technician obtains the to-be-analyzed dynamometer card of the rod pump pumping unit well by the polished rod dynamometer, compares the obtained to-be-analyzed dynamometer card with the dynamometer card of the dynamometer card area 111 of the main disc 100, finds the similar dynamometer card, looks up the number of the first analysis number area 113 corresponding to the similar dynamometer card, rotates the auxiliary disc 200, the first transparent area 215 can rotate relative to the second main disc surface 120, so that the corresponding area on the second main disc surface 120 can be seen by the technician, so that the equal number can be found in the second analysis number area 122 of the second main disc surface 120 of the main disc 100 or the third analysis number area 212 of the first auxiliary disc surface 210 of the auxiliary disc 200, the first dynamometer card analysis area 121 or the second dynamometer card analysis area 211 corresponding to the number is the analysis process of the to-be-analyzed dynamometer card, and the number of the first measure number area 123 or the second measure number area 213 corresponding to the number is the type number of the measure, and then the corresponding measure can be found in the measure area 214 and implemented.

[0041] Example 2. The number of the first analysis number area 113 corresponding to the similar dynamometer card of the to-be-analyzed dynamometer card is 24, the auxiliary disc 200 is rotated, and the analysis process corresponding to the number 24 in the third analysis number area 212 is looked up in the Figure 4 corresponding second measure number area 213 is 18, and then the No. 18 measure is found in the measure area 214 and implemented.

[0042] It should be noted that Figure 3 the dynamometer card analysis corresponding to the number 1 in the second analysis number area 122 is the normal working dynamometer card analysis process, so no operation is needed, and there is no corresponding measure number.

Figure 3

[0047] In some embodiments, as shown in FIG. 1, the second main surface 120 of the main disc 100 is provided with a second transparent area 125, which is a central circular area. The size of the second transparent area 125 is greater than that of the first analysis number area 113, so that a technician can directly see the contents of the first analysis number area 113 from one side of the main disc 100.

In implementation, the arrow 217 can be colored, for example, red, which is more obvious. Figure 4

[0049] In some embodiments, the diameters of the main disc 100 and the auxiliary disc 200 are both 210 mm, so that the overall size of the entire diagnostic disc is 210 mm, which is equivalent to the width of an A4 paper, facilitating the technician to carry it, and also enabling the technician to clearly see the contents of the main disc 100 and the auxiliary disc 200. In implementation, the thickness of the main disc 100 can be 1 mm, and the thickness of the auxiliary disc 200 can be 0.8 mm, which are also convenient for carrying.

[0050] ​​​​In some embodiments, the main disc 100 is made of white PVC plate, and the auxiliary disc 200 is made of transparent PVC plate. The PVC plate is solid and wear-resistant, durable, and not easy to stick to impurities such as oil stains.
