Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of temporary plugging agents, and particularly relates to a temporary plugging agent quantitative feeding device for temporary plugging and fracturing. BACKGROUND

[0002] A temporary plugging agent is a material used for temporarily blocking a specific formation or fracture in oil and gas field fracturing operations. Its main function is to prevent certain liquids or gases from flowing for a short time during fracturing, ensuring that the fracturing fluid can accurately flow to the area that needs to be fractured and will not penetrate into the area that does not need to be fractured. The temporary plugging agent plays a crucial role as a temporary blocking medium during fracturing. With the widespread use of temporary plugging agents, a temporary plugging agent quantitative feeding device for temporary plugging and fracturing is particularly important.

[0003] The utility model with the authorized publication number CN221643930U discloses a temporary plugging agent quantitative feeding device for temporary plugging and fracturing, which comprises a bottom plate, a box body fixedly connected to the top of the bottom plate, a motor one fixedly connected to the top of the box body, a rotating shaft fixedly connected to the output end of the motor one, uniformly distributed stirring rods fixedly connected to the outer wall of the rotating shaft, a baffle fixedly connected to the middle of the inner wall of the box body, a sliding plate slidingly connected to the front end of the baffle, left and right fixed blocks fixedly connected to the front end of the box body, and a threaded rod rotatably connected between the two fixed blocks.

[0004] By the mutual cooperation of the rotating shaft, the stirring rods, the baffle, the sliding plate, the threaded rod, the fixed blocks, and the beveled blocks, the above technical solution realizes the tilting discharge of the feeding device, avoids the need to manually tilt the entire device, and simultaneously stirs the temporary plugging agent to make it more loose and avoid accumulation. The auxiliary plugging agent is also pushed into the through hole to avoid partial blockage or remaining on the baffle. However, the above technical solution cannot adjust the size of the hole according to the size of the temporary plugging agent particles during use, which limits the use range of the device. Meanwhile, the manual adjustment of the multiple through holes of the baffle and the sliding plate to correspond to each other causes the temporary plugging agent in the upper part of the box body to fall into the lower part of the box body, which not only reduces the working efficiency of the device but also easily causes the temporary plugging agent to block when the baffle and the sliding plate are misaligned. The technical solution fails to timely detect and effectively handle the blockage of the device, further reducing the use effect of the device.

[0005] Therefore, we propose a temporary plugging agent quantitative feeding device for temporary plugging and fracturing to solve the above problems. CONTENT OF THE UTILITY MODEL
