[0002] Fracturing sand is a kind of high-purity quartz sand, which is finely processed and has strong compressive resistance and roundness. This kind of fracturing sand is often used in the petroleum industry as a petroleum proppant and is an indispensable substance. After the quartz sand is screened, it needs to be sampled for testing. Through sampling, the distribution of fracturing sand in the fracture can be understood, and then the effect of the fracturing operation can be evaluated. It helps to judge key information such as whether the fracture is fully extended and whether the proppant is effectively filled. At present, the sampling of quartz sand is carried out by manually using a shovel to sample different areas. This method is not only time-consuming and laborious but also has low efficiency.

[0020] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail the quartz sand sampling device for fracturing of the present utility model with reference to the drawings.

[0021] As Figures 1 to 3As shown in the figure, a sampling device for quartz sand used in fracturing of the present utility model includes a sampling frame. The sampling frame is provided with a through hole from top to bottom. A first handle 6 is provided on the outer wall of the sampling frame, and the first handle 6 is symmetrically arranged with respect to the center of the sampling frame, which facilitates the manual grasping and use of the sampling frame. In order to prevent the quartz sand from detaching from the sampling frame, an anti-detachment component 4 is rotatably arranged at the inner bottom end of the sampling frame. When using the sampling device for quartz sand used in fracturing, one can hold the first handle 6, then align the bottom opening of the sampling frame with the position of the quartz sand to be sampled and insert it. After inserting it to an appropriate position, then pull out the sampling frame to complete the sampling work of the sampling frame for the quartz sand.

[0022] The above-mentioned sampling frame includes a bearing frame 1 and a cover plate 2. The cover plate 2 is rotatably arranged with the bearing frame 1 through a connecting member, and a lock 3 for connecting with the cover plate 2 is provided on the bearing frame 1. After the sampling frame finishes sampling the quartz sand, open the lock 3 to release the connection between the cover plate 2 and the sampling frame, and then the detection of the quartz sand at each position in the sampling frame can be carried out. Specifically, the connecting frame is preferably a hinge 8, and the thin hinge 8 can reduce the friction when the sampling frame is inserted into the quartz sand.

[0023] The anti-detachment component 4 for preventing the quartz sand in the sampling frame from falling off is rotatably arranged in the bearing frame 1, and the anti-detachment component 4 is symmetrically arranged with respect to the center of the bearing frame 1. The anti-detachment component 4 specifically includes a connecting ring 41 provided on the inner bottom wall of the bearing frame 1. The connecting ring 41 is symmetrically arranged with respect to the center of the bearing frame 1. A rotating shaft 42 is rotatably arranged on the connecting ring 41. A flap 44 is provided on the rotating shaft 42, and the flap 44 is connected with the inner wall of the bearing frame 1 through a traction rope 45, so that the flap 44 is inclined with respect to the bearing frame 1, and the free ends of the two flaps 44 are in contact to form a closed state for the lower port of the bearing frame 1, thereby achieving the effect of blocking the quartz sand in the bearing frame 1. A torsion spring 43 is also sleeved on the rotating shaft 42, and one end of the torsion spring 43 is connected with the bearing frame 1, and the other end is connected with the flap 44. During the process of inserting the bearing frame 1 into the quartz sand, the quartz sand entering the bearing frame 1 will push the inclined flap 44 upwards. When the flap 44 rotates, it will apply a force to the torsion spring 43. After the bearing frame 1 finishes sampling and is pulled out from the quartz sand, during the pulling-out process, the torsion spring 43 pushes the flap 44 to rotate towards the initial position, so that the free ends of the two flaps 44 are in contact again, achieving the purpose of blocking the quartz sand in the bearing frame 1.

[0024] Preferably, a discharging component 5 is inserted into the carrying frame 1. Through the discharging component 5, the samples in the material taking frame can be quickly removed, saving the time of opening the cover plate 2 and improving work efficiency. Specifically, the discharging component 5 includes two extension plates 51 inserted into the carrying frame 1, and each extension plate 51 is connected to the carrying frame 1 through a buckle 3 so that the extension plate 51 is fixed on the carrying frame 1. A connecting plate 52 is also provided at the top ends of the two extension plates 51, and the connecting plate 52 is used to connect the two extension plates 51. In order to increase the stability of the two extension plates 51, the bottom ends of the two extension plates 51 are connected by a support plate 53. And an anti-disengagement component 4 is provided on the inner wall of the bottom end of the extension plate 51. The extension plate 51 is fixed to the bearing plate through the buckle 3, and then the first handle 6 is held to insert the carrying frame 1 together with the cover plate 2 into the quartz sand. When the carrying frame 1 is inserted, the carrying frame 1 carries the discharging component 5 and the anti-disengagement component 4 into the quartz sand through the buckle 3. After inserting to an appropriate position, the carrying frame 1 is pulled out, and the sampling work of the quartz sand is completed. When it is necessary to remove the quartz sand in the carrying frame 1, the fixation between the extension plate 51 and the bearing plate can be released, and then the extension plate 51 and the anti-disengagement component 4 are pulled out of the bearing shell through the connecting plate 52. When the anti-disengagement component 4 is pulled out, the quartz sand in the carrying frame 1 will be pulled out, which is convenient, fast and simple to operate. To facilitate the use of the discharging component 5, a second handle 7 is provided at the top end of the connecting plate 52. And in order to know the depth of insertion of the carrying frame 1 into the quartz sand, a scale 11 is provided on the outer wall of the carrying frame 1.

[0025] Specifically, the buckle 3 includes a C-shaped buckle 31 and a convex block 32. The C-shaped buckle 31 is provided on the side wall of the carrying frame 1, and convex blocks 32 are provided on both the cover plate 2 and the extension plate 51, and the convex block 32 cooperates with its corresponding C-shaped buckle 31. As Figure 1 shown, the convex block 32 on the extension plate 51 can limit its position on the bearing plate to prevent the extension plate 51 and the anti-disengagement component 4 connected thereto from crossing the bottom opening of the carrying frame 1. And the convex block 32 provided on the cover plate 2 will also be limited on the carrying frame 1 to prevent the cover plate 2 from crossing the carrying frame 1. During use, the C-shaped buckle 31 is rotated onto the convex block 32 to complete the connection between the C-shaped buckle 31 and the convex block 32.

[0026] Usage method: Use the buckle 3 to connect the carrying frame 1 with the extension plate 51 on the discharging component 5, and use another buckle 3 on the carrying frame 1 to connect the carrying frame 1 with the cover plate 2. Then hold the first handle 6, align the bottom opening of the carrying frame 1 with the sampling position and insert it. When inserting, the anti-disengagement component 4 is lifted, so that the quartz sand enters the carrying frame 1. Then the carrying frame 1 is pulled out. When pulling out, the two flap plates 44 in the two anti-disengagement components 4 rotate towards the initial position and close the bottom opening of the carrying frame 1 to prevent the quartz sand in the carrying frame 1 from flowing out. Thus, the sampling of the quartz sand is completed.
