Description

Technical Field

[0001] This utility model relates to the field of filling tool technology, specifically a filling tool for oilfield well completion. Background Technology

[0002] In oilfield well completion operations, filling tools are used to precisely deliver filling materials such as sand and gravel to the downhole center pipe or target area to achieve functions such as formation isolation and well wall support.

[0003] Traditional sand and gravel filling typically relies on gravity, where sand and gravel are poured directly into the wellhead and allowed to settle naturally into the annulus or screen pipe below the well, filling the target space. However, sand and gravel particles vary in size, and without screening, large particles can get stuck in narrow spaces, hindering subsequent filling and causing interruptions. Furthermore, large pieces of sand and gravel can enlarge the gaps in the filling. Therefore, we need a filling tool for oilfield well completion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filling tool for oilfield well completion. Through the cooperation of a screening component and a conveying component, the filling sand and gravel can be screened to ensure that the sand and gravel are of uniform size and to prevent large particles from clogging narrow places and hindering subsequent sand and gravel filling.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a filling tool for oilfield well completion, comprising: a conveyor frame, a conveyor belt installed on the inner wall of the conveyor frame, a screening component provided at the upper end of the conveyor frame, and a conveying component provided on the right side of the conveyor frame;

A screening frame is fixedly connected to the opposite side of the two sliding blocks. A frame is fixedly connected to one side of the screening box. Two turntables are rotatably connected to the inner wall of the frame. A traction rod is rotatably connected between the two turntables through a rotating shaft. The end of the traction rod away from the turntable is rotatably connected to a traction frame through a rotating shaft. Two guide rods are fixedly connected to one side of the traction frame.

[0007] Preferably, the conveying assembly includes a funnel fixedly connected to the right side of the conveying frame, a conveying pipe fixedly connected to the lower end of the funnel, a motor fixedly connected to one side of the conveying pipe, a rotating rod fixedly connected to one end of the motor through the conveying pipe, and a spiral blade fixedly connected to the outer wall of the rotating rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a filling tool for oilfield well completion, including: a conveyor frame 1, a conveyor belt 2 installed on the inner wall of the conveyor frame 1, and the conveyor belt 2 is the existing technology, which mainly uses a motor to drive the conveyor belt to transport sand and gravel, which will not be described in detail. A screening component 3 is provided at the upper end of the conveyor frame 1, and a conveying component 4 is provided on the right side of the conveyor frame 1.

[0024] The screening assembly 3 includes a screening box 301 fixedly connected to the upper end of the conveyor frame 1. An inlet 302 is fixedly connected to the upper end of the screening box 301. Slide grooves 303 are formed on the front and rear sides of the inner wall of the screening box 301. Sliding blocks 304 are slidably connected to the inner walls of both slide grooves 303. Screening frames 305 are fixedly connected to the opposite sides of the two sliding blocks 304. A frame 306 is fixedly connected to one side of the screening box 301. Two turntables 307 are rotatably connected to the inner wall of the frame 306. A traction rod 308 is rotatably connected between the two turntables 307 via a rotating shaft. A traction frame 309 is rotatably connected to the end of the traction rod 308 away from the turntables 307 via a rotating shaft. Two guide rods 310 are fixedly connected to one side of the traction frame 309. The screening assembly 3 screens the filled sand and gravel to ensure that the sand and gravel meet the required filling size.

[0025] The conveying assembly 4 includes a funnel 401 fixedly connected to the right side of the conveying frame 1. A conveying pipe 402 is fixedly connected to the lower end of the funnel 401. A motor 403 is fixedly connected to one side of the conveying pipe 402. A rotating rod 404 is fixedly connected to one end of the motor 403, which passes through the conveying pipe 402. A spiral blade 405 is fixedly connected to the outer wall of the rotating rod 404. The conveying assembly 4 can convey the screened sand and gravel to the central pipe.

[0026] The ends of the two guide rods 310 away from the traction frame 309 both pass through the screening box 301 and are fixedly connected to one side of the screening frame 305, and the guide rods 310 are slidably connected to the screening box 301. The movement of the guide rods 310 drives the screening frame 305 to move inside the screening box 301.

[0027] Buffer pads 3011 are installed on the inner wall of the screening box 301 and on both the left and right sides of the screening frame 305. A through hole is opened at the lower end of the screening box 301. The buffer pads 3011 reduce the collision between the screening frame 305 and the inner wall of the screening box 301 during the movement, while the through hole facilitates the screening of sand and gravel to fall into the upper end of the conveyor belt 2.

[0028] A second motor 3061 is fixedly connected to the front side of the frame 306. The output end of the second motor 3061 passes through the frame 306 and is fixedly connected to one side of a turntable 307. The turntable 307 is driven to rotate by the second motor 3061.

[0029] Four support frames 5 are fixedly connected to the lower end of the conveyor frame 1, and the four support frames 5 are arranged symmetrically. The stability of the conveyor frame 1 is improved by the four support frames 5.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the required sand and gravel are fed into the screening box 301 through the feed inlet 302 and fall into the screening frame 305. At this time, the motor 3061 is started to drive the turntable 307 to rotate. The rotation of the turntable 307 drives the guide rod 310 to slide through the traction rod 308 and the traction frame 309. The sliding of the guide rod 310 causes the screening frame 305 to reciprocate within the screening box 301, screening the sand and gravel and removing sand and gravel that do not meet the specified size. In addition, during the movement of the screening box 301, the buffer pad 3011 reduces the size of the screening frame 305. The collision with the inner wall of the screening box 301, and when the screening frame 305 moves to the rightmost or leftmost position of the inner wall of the screening box 301 via the slider 304, the lower end of the feed port 302 is still at the upper end of the screening frame 305, ensuring the normal feeding of sand and gravel. The screened sand and gravel are conveyed by the conveyor belt 2 and fall into the funnel 401. The sand and gravel enter the conveying pipe 402 through the funnel 401. At this time, the motor 403 is started to drive the rotating rod 404 to drive the spiral blade 405 to convey the sand and gravel at a uniform speed, ensuring that the sand and gravel are sent into the central pipe.
