[0002] Oilfield acid fracturing, referred to as acid fracturing, is the use of acid as fracturing fluid at a pressure higher than the formation fracture pressure. During the development of oil fields, due to the need for fracturing and acidification, temporary plugging balls can temporarily reduce the permeability of the formation or temporarily plug the high permeability oil layer material. After being mixed with water-soluble polymers and injected into the well, a thin and dense temporary plugging zone of the oil layer can be quickly formed under the action of pressure difference. After a certain period of time, the plugging can be automatically or manually unblocked. Therefore, it is necessary to put the temporary plugging balls into the wellbore or wellbore through a feeding device;

[0024] In this embodiment, the top of the feeding box 1 is fixedly connected to an arc-shaped support plate 8, and the top of the arc-shaped support plate 8 is fixedly connected to a bottom plate 9;

[0025] The bottom plate 9 can block the unused discharge holes 15 , thereby blocking the temporary blocking balls inside, and the arc-shaped support plate 8 can support the bottom plate 9 .

[0026] In this embodiment, a connecting pipe 10 is fixedly connected to the outer wall of the feeding box 1, and the connecting pipe 10 and the annular groove 2 are connected through a second through hole. A conical leakage pipe 11 is fixedly connected to the top of the connecting pipe 10, and the conical leakage pipe 11 is fixedly connected to the bottom plate 9;

[0027] The bottom plate 9 is supported and reinforced again by the connecting pipe 10 and the conical leakage pipe 11, and the temporary plugging balls can flow into the annular groove 2 through the cooperation of the connecting pipe 10 and the conical leakage pipe 11, so that the material can be continuously fed to the fracturing site.

[0028] In this embodiment, a second motor 12 is fixedly connected to one side of the arc-shaped support plate 8 at the top of the feeding box 1, a driving shaft 13 is fixedly connected to the driving end of the second motor 12 and passes through the bottom plate 9, a discharge column 14 is fixedly connected to the top of the drive shaft 13, and a plurality of discharge holes 15 are pierced on the discharge column 14;

[0029] When the temporary plugging balls in one discharge hole 15 are used up, the next discharge hole 15 is replaced, and the temporary plugging balls are added to the used discharge hole 15, so there is no need to stop for replenishment, which is convenient for subsequent fracturing treatment.

[0030] In this embodiment, the diameters of the plurality of discharge holes 15 are the same as the inner diameter of the top end of the conical leakage pipe 11, and the diameters of the bottom plate 9 and the discharge column 14 are the same;

[0031] The diameter of the temporary blocking ball is smaller than the discharge hole 15 and the conical leakage pipe 11, which facilitates the falling of the temporary blocking ball.

[0032] In this embodiment, a plurality of indicator rods are fixedly connected to the center of the discharge hole 15 on the outer wall of the discharge column 14, an indicator block is fixedly connected to the center of the conical leakage pipe 11 on the outer wall of the bottom plate 9, the second through hole is inclined, the second through hole facilitates the falling of the temporary blocking ball, and the first through hole is horizontally arranged;

[0034] It should be noted that the utility model is a fracturing temporary plugging feeding device. When in use, the discharge holes 15 can be filled with temporary plugging balls, and then one of the discharge holes 15 is aligned with the conical leakage pipe 11. At this time, the temporary plugging balls fall and flow into the annular groove 2 through the connecting pipe 10. When the temporary plugging balls in one of the discharge holes 15 have fallen, the second motor 12 is started to rotate the drive shaft 13, so that the discharge column 14 rotates.
