[0026] See also Figure 1-Figure 5 The utility model provides an embodiment: a quantitative water distribution device for oil field water injection wells that is convenient to adjust, comprising an upper connecting pipe 1, a connecting ring 2, a water guide pipe 3, and a lower connecting pipe 6. The bottom end of the upper connecting pipe 1 is connected to the connecting ring 2, and the bottom end of the connecting ring 2 is connected to the water guide pipe 3. One end of the water guide pipe 3 extends to the inside of the upper connecting pipe 1, and the bottom end of the water guide pipe 3 is connected to the lower connecting pipe 6. A sealing ring 5 is adhered to the outer side of one end of the water guide pipe 3, and an adjusting mechanism 7 is arranged inside the water guide pipe 3;

[0027] The adjusting mechanism 7 includes a driven shaft 701, and the driven shaft 701 is arranged inside the water pipe 3, an adjusting block 708 is sleeved on the outside of the driven shaft 701, and a connecting block 702 is fixed on one side of the adjusting block 708, a sealing sheet 703 is adhered to one side of the connecting block 702, a driven bevel gear 706 is sleeved on the outside of the top of the driven shaft 701, a driving bevel gear 707 is meshed on one side of the driven bevel gear 706, a clamping block 705 is fixed on both sides of the driven bevel gear 706 and the driving bevel gear 707, an adjusting rod 704 is passed through the inside of the driving bevel gear 707, and one end of the adjusting rod 704 extends to the outside of the lower connecting pipe 6;

[0028] The cross section of the sealing sheet 703 is arc-shaped, and the material of the sealing sheet 703 is rubber;

[0029] There are two groups of driven bevel gears 706, each group of driven bevel gears 706 is provided with two, and the cross-sections of the two groups of driven bevel gears 706 are both annular;

[0030] Specifically, Figure 1 , Figure 5 As shown, when in use, by screwing the adjusting rod 704, the driven shaft 701 is driven to rotate under the action of the clamping block 705 and the active bevel gear 707, thereby driving the adjusting block 708 to move downward, and under the action of the connecting block 702, the sealing sheet 703 is moved away from the water nozzle 8. Through the above operation, the amount of water injection can be quickly adjusted, thereby improving practicality;

[0031] A water nozzle 8 is provided on one side of the water pipe 3, and a water storage tank 9 is provided inside the lower connecting pipe 6 on one side of the water nozzle 8, and a water injection mechanism 4 is provided inside the lower connecting pipe 6;

[0032] The water injection mechanism 4 includes a floating block 402, and the floating block 402 is arranged on the outside of the water pipe 3, the top of the floating block 402 is provided with a support column 403, and the top of the support column 403 is adhered with a sealing gasket 404, and the top of the sealing gasket 404 is adhered with a stopper 401;

[0033] The cross section of the floating block 402 is in a circular ring shape, and the floating block 402 is made of foam plastic material;

[0034] There are two support columns 403, and the two support columns 403 are symmetrically distributed;

[0035] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, when the interior of the water storage tank 9 is filled with water, the float block 402 generates buoyancy, and under the action of the support column 403, the stopper 401 is pushed to move upward, thereby injecting water into the formation, thereby improving the work efficiency of the water injection.

[0036] Working principle: When the utility model is in use, first, when water is injected, the active bevel gear 707 is driven to rotate by screwing the adjusting rod 704. Since the active bevel gear 707 and the driven bevel gear 706 are meshed with each other, the active bevel gear 707 rotates and drives the driven bevel gear 706 to rotate synchronously. The clamping block 705 can limit the moving driven bevel gear 706 and the active bevel gear 707 to avoid positional deviation during the movement. The driven bevel gear 706 rotates and drives the driven shaft 701 to rotate synchronously, thereby driving the adjusting block 708 to move downward, and driving the sealing plate 703 to move downward synchronously under the action of the connecting block 702, so that the sealing plate 703 is away from the water nozzle 8. The above operation makes it easy to adjust the size of the water nozzle 8, thereby achieving the purpose of adjusting the water injection amount, thereby improving its practicality.

[0037] Then, water is injected through the upper connecting pipe 1, enters the interior of the water pipe 3, and is discharged into the interior of the water storage tank 9 through the water nozzle 8 until the surface of the water fits against the floating block 402. During the continuous water injection process, the floating block 402 is affected by the buoyancy and moves upward. While the floating block 402 moves upward, it pushes the support column 403 to move upward synchronously, thereby pushing the block 401 to move upward synchronously, until one side of the sealing pad 404 is away from the lower connecting pipe 6, thereby facilitating the injection of water into the formation. The above operation facilitates the rapid water injection operation, thereby improving its work efficiency.
