Detailed implementation manners

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0024] An embodiment of the present utility model discloses a simulation plugging experiment device for a new type of polymer plugging agent.

[0025] The present utility model provides a simulation plugging experiment device for a new type of polymer plugging agent as shown in Figures 1-3 which includes a bottom plate 1 and a support block 2. A plurality of support legs 3 are fixedly arranged between the bottom plate 1 and the support block 2. A support frame 4 is fixedly arranged on the top of the support block 2. A plurality of detection holes 5 are formed in the support block 2 and are arranged in a circumferentially symmetric manner. A cracking detection block 6 is arranged in each detection hole 5 through a clamping assembly. A vertical rod 7 is rotatably penetrated through the support block 2. A motor 8 is fixedly arranged on the top of the bottom plate 1. The motor 8 is a reduction motor. The output end of the motor 8 is fixedly connected to the vertical rod 7. A horizontal plate 9 is fixedly sleeved on the upper end of the vertical rod 7. A feeding pipe 10 is fixedly penetrated through the horizontal plate 9. A discharge pipe 11 is communicated with the bottom of the feeding pipe 10. A check valve 19 is fixedly sleeved on the pipe wall of the discharge pipe 11. An extrusion discharging mechanism for discharging is arranged between the upper end inside the feeding pipe 10 and the support frame 4. The extrusion discharging mechanism includes a push rod 12. A piston for pushing 13 is fixedly arranged at the bottom of the push rod 12. The piston for pushing 13 is arranged inside the feeding pipe 10. A plurality of pushing blocks 14 are fixedly arranged on the inner wall top of the support frame 4 and are arranged in a circumferentially symmetric manner. The lengths of the plurality of pushing blocks 14 are arranged in a circular increasing manner. The plurality of pushing blocks 14 are arranged in cooperation with the push rod 12. A plurality of water receiving plates 18 are fixedly arranged on the top of the bottom plate 1. The water receiving plates 18 are arranged in cooperation with the detection holes 5.

[0026] Before conducting the simulation experiment, pull the push piston 13 out of the feeding pipe 10, put the leak plugging agent into the feeding pipe 10, and then insert the push piston 13 back into the feeding pipe 10. Subsequently, place a plurality of cracking detection blocks 6 into the detection holes 5 and determine the positions of the detection blocks. Then, start the motor 8 so that the vertical rod 7 drives the cross plate 9 and the feeding pipe 10 to rotate. During this process, the top of the push rod 12 contacts and cooperates with the push block 14, and the push rod 12 is driven by the push block 14 to move downward, causing the push piston 13 to push the leak plugging agent in the feeding pipe 10 through the discharge pipe 11 and the one-way valve 19 and drop it on the cracking positions of the detection blocks. As the length of the push block 14 increases, the push rod 12 continuously moves downward, and the tops of multiple detection blocks are coated with the leak plugging agent, thereby reducing manual operation. Finally, spray water on the tops of multiple detection blocks, and judge the leak plugging effect of the leak plugging agent by observing whether there are water droplets on the surface of the water receiving plate 18.

[0027] In order to fix the detection positions of the cracking detection blocks 6, as Figures 2-3 shown, the clamping assembly includes a bidirectional lead screw 15. Two symmetrically arranged clamping plates 16 are in contact with the inner wall of the detection hole 5. The cracking detection block 6 is arranged between the two clamping plates 16. The bidirectional lead screw 15 is rotatably arranged in the detection hole 5 and is threadedly arranged inside the clamping plate 16. A rotating block 17 is fixedly sleeved on the rod wall of the bidirectional lead screw 15.

[0028] After the cracking detection block 6 is placed in the detection hole 5, push the rotating block 17, so that the rotating block 17 drives the bidirectional lead screw 15 to rotate, and thus the two clamping plates 16 can approach each other and stably clamp the cracking detection block 5, thereby completing the determination of the position of the cracking detection block 6 and improving the experimental stability.

[0029] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
