Examples:
Referring to fig. 1 and 2, a pressurized delivery device of a solid temporary plugging agent comprises a sleeve 1, a piston 2, a connecting rod 3, a driving assembly, an input pipe 4, an input one-way valve 5, an output pipe 6 and an output one-way valve 7.
Specifically, two sides of one end of the sleeve 1 are respectively provided with a hole, so that the outside of the sleeve 1 is communicated with the inside of the sleeve through the two holes, and the other end of the sleeve 1 is provided with a movable hole.
The two sleeves 1 are oppositely arranged, one ends of the two sleeves 1 with movable holes are close to each other, a certain distance is reserved between the two sleeves 1, and a piston 2 is slidably arranged in each sleeve 1.
The two ends of the connecting rod 3 respectively penetrate from the movable holes on the two sleeves 1 and are respectively connected with the two pistons 2. The connecting rod 3 is in sliding connection with the movable hole.
The input pipe 4 has three ends, one input check valve 5 is provided on each of the two ends, and the two ends of the input pipe 4 provided with the input check valves 5 are fixedly provided on the holes on one side of the two sleeves 1, respectively. The third end of the input pipe 4 is communicated with the supply end of the solid temporary plugging agent fluid.

The third end of the output pipe 6 is connected to a pipe in the injection well.
The solid temporary plugging agent fluid passing through the input check valve 5 can only flow into the sleeve 1, and the solid temporary plugging agent fluid passing through the output check valve 7 can only flow out of the sleeve 1.
The working principle of this embodiment is that firstly, one piston 2 is respectively arranged in two sleeves 1, and two pistons 2 are connected into a whole through one connecting rod 3, and then the connecting rod 3 is driven by a driving component to reciprocate along the length direction.
In this process, when the connecting rod 3 moves in the direction of one of the sleeves 1, the fluid in the piston 2 flows out of the sleeve 1, and the piston 2 in the other sleeve 1 moves to suck in the fluid.
Since one input check valve 5 is respectively installed at both ends of the input pipe 4, and the output check valve 7 is respectively installed at both ends of the output pipe 6. Thus, when one of the pistons 2 drives the fluid in the sleeve 1 out, the input check valve 5 on the input pipe 4 is closed and the output check valve 7 on the output pipe 6 is opened.
In this embodiment, the piston 2 in the two sleeves 1 is driven to move simultaneously by the driving assembly, so that continuous injection of temporary plugging agent fluid with pressure into the well is realized. Because the temporary plugging agent fluid obtains energy, the flow speed of the temporary plugging agent fluid is increased, and therefore, the probability of depositing solid temporary plugging agent with larger particles in the well is greatly reduced.
In one particular embodiment:
The drive assembly comprises a drive rod 8, a drive plate 9, a rotating shaft 10, a cam 11 and a motor 12. Wherein, the one end of actuating lever 8 sets up perpendicularly in the middle part of connecting rod 3, and actuating lever 8 is located between two sleeves 1.
The driving plate 9 is long-strip-shaped, the middle part of the driving plate 9 is provided with a driving groove, the driving groove penetrates through the top surface and the bottom surface of the driving plate 9 and is sleeved on one end, far away from the connecting rod 3, of the driving rod 8, and the driving groove is in sliding contact with the driving rod 8.

Preferably, the diameter of the protruding end of the cam 11 is equal to or less than the length of the inside of the sleeve 1. The orientation, steering and rotational speed of the two cams 11 are identical.
In this embodiment, the two motors 12 are synchronously started and stopped, and synchronously drive the two cams 11 to rotate, so that the driving plate 9 drives the driving rod 8 to slide in the driving groove, and when the cams 11 rotate, the driving plate 9 can drive the driving rod 8 to reciprocate along the length direction of the connecting rod 3.
In one particular embodiment:
One end of the driving rod 8, which is contacted with the inner wall of the driving groove, is provided with a rotor 13, and the diameter of the rotor 13 is smaller than the width of the driving groove. By providing the rotor 13 at the end of the drive rod 8, the friction factor between the drive rod 8 and the inner wall of the drive slot can be reduced, thereby slowing down the wear rate.
In another specific embodiment:
The input check valve 5 has the same structure as the output check valve 7, and the input check valve 5 includes a connection pipe 14, a ball 15, and a spring 16, taking the input check valve 5 as an example.

In this embodiment, the inlet of the connecting pipe 14 is flowed into the solid temporary plugging agent fluid and then impinges on the pellets 15, the pellets 15 acquire pressure and compress the springs 16, thereby separating the pellets 15 from the inlet and achieving conduction. Conversely, when the outlet of the connecting pipe 14 flows into the solid temporary plugging agent fluid, the fluid impacts on the small ball 15 and drives the small ball 15 to move towards the inlet, and in the process, the small ball 15 is plugged on the inlet under the restoring force of the spring 16 to form a plug.
Preferably, the ball 15 has a plurality of introduction holes 17 in the circumferential direction, all of the introduction holes 17 are distributed around the axis of the connection pipe 14, one of the introduction holes is provided in the middle of one end of the ball 15 connection spring 16, and the introduction holes communicate with all of the introduction holes 17.
