Description

Technical Field

[0001] This utility model belongs to the field of reagent storage technology, specifically relating to a storage container for iron ion stabilizer used in fracturing and acidification that is easy to stack. Background Technology

[0002] Iron ion stabilizers for fracturing and acidizing are oilfield chemical additives mainly used to suppress iron ions during acidizing or fracturing operations.

[0003] For iron ion stabilizers used in fracturing and acidizing, the conventional storage method is to store them in storage drums. The storage specifications are generally 50.0kg±0.5kg / drum or 200.0kg±2.0kg / drum. Based on the principle of avoiding deformation or damage to the storage drums due to heavy pressure, the storage drums should be stacked in single or double layers (not exceeding 3 layers).

[0004] For the handling of iron ion stabilizer storage tanks used in fracturing and acidizing, it is generally required that the storage tanks be strictly prohibited from rolling, colliding or tipping over. Therefore, existing transport vehicles need to fix the tanks to prevent displacement, which requires additional transfer racks or fixing devices, increasing transportation costs. Installing and removing transfer racks or fixing devices will increase transportation time and reduce transportation efficiency. Utility Model Content

This solves the problem that existing transport vehicles need to fix the tank to prevent displacement, which requires additional transfer racks or fixing devices, increasing transportation costs. Furthermore, installing and removing transfer racks or fixing devices increases transportation time and reduces transportation efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, a storage container for iron ion stabilizer used in fracturing and acidizing, which is easy to stack, includes:

[0028] Barrel body 1; The inner side wall at the top of barrel body 1 is provided with threads;

[0029] Bucket lid 7; The outer wall of bucket lid 7 is provided with threads, and bucket body 1 and bucket lid 7 can be engaged with each other through the threads;

[0030] Two first arc grooves 2; the first arc groove 2 is a blind groove structure with one end closed and the other end open. The first arc groove 2 is set vertically. The two first arc grooves 2 are symmetrically distributed on the outer side wall of the barrel 1 along the central axis of the barrel 1. The open end of the first arc groove 2 is set towards the top of the barrel 1.

[0031] Two second arc grooves 4; the second arc groove 4 is a blind groove structure with one end closed and the other end open. The second arc groove 4 is set vertically. The two second arc grooves 4 are symmetrically distributed on the outer side wall of the barrel 1 along the central axis of the barrel 1. The open end of the second arc groove 4 faces the bottom of the barrel 1. The plane where the two second arc grooves 4 are located is perpendicular to the plane where the two first arc grooves 2 are located. The sum of the length of one first arc groove 2 and the length of one second arc groove 4 is equal to the height of the barrel 1. The depth and width of the first arc groove 2 and the second arc groove 4 are the same. The arc diameter of the first arc groove 2 and the second arc groove 4 is equal to the outer diameter of the barrel 1.

[0032] Fixed insert plate 5; Fixed insert plate 5 is set on the groove surface of the closed end of the second arc groove 4, and the groove surface of the closed end of the first arc groove 2 is provided with a fixing hole 3 that can cooperate with the fixed insert plate 5.

[0033] In this embodiment, the present application provides a first arc groove 2 and a second arc groove 4 that can cooperate with each other. During transportation or stacking, each first arc groove 2 of a barrel 1 can cooperate with a second arc groove 4, so that a fixing plate 5 is inserted into a fixing hole 3, thereby restricting the relative rotation between barrels 1. At the same time, the planes on which the two second arc grooves 4 on a barrel 1 are located are perpendicular to the planes on which the two first arc grooves 2 are located. This structure allows any barrel 1 to cooperate with four other identical barrels 1. Moreover, the present application achieves the cooperation of the fixing plate 5 and the fixing hole 3 by opening arc grooves on the barrel wall, which saves more space and improves space utilization compared to adding male and female buckles on the outside of the barrel wall.

[0034] Example 2: The difference between this example and Example 1 is that, as Figure 2 As shown, a limiting ring 9 is provided on the inner side wall of the top of the storage barrel. The outer side of the limiting ring 9 is fixedly connected to the inner side wall of the storage barrel. When the barrel cover 7 is screwed on by the thread until it is pressed against the top surface of the limiting ring 9, the barrel cover 7 is in a tightened state.

[0035] Example 3: The difference between this example and Example 2 is that, as Figure 2 As shown, the storage bucket also includes a rubber gasket 10, which is stacked on the limiting ring 9. The bottom surface of the rubber gasket 10 is fixedly connected to the top surface of the limiting ring 9. When the bucket lid 7 is in the tightened state, the bottom surface of the bucket lid 7 is pressed against the top surface of the rubber gasket 10.

[0036] Example 4: The difference between this example and Example 3 is that the rubber gasket 10 is made of fluororubber.

[0037] In this embodiment, fluororubber exhibits excellent resistance to strong acids, strong alkalis, organic solvents, fuel oil, and salt spray, and can operate in environments where iron ion stabilizers are present in fracturing and acidizing processes.

[0038] Example 5: The difference between this example and Example 3 is that, as Figure 2 As shown, a limiting block 8 is provided at the bottom of the barrel 1. The limiting block 8 is a flat cylinder. The top surface of the limiting block 8 is fixedly connected to the bottom surface of the barrel 1. The central axis of the limiting block 8 coincides with the central axis of the barrel 1. The diameter of the limiting block 8 is equal to the inner diameter of the barrel 1. The height of the limiting block 8 is equal to the distance between the top of the barrel and the barrel lid 7 when the lid 7 is in the tightened state.

[0039] In this embodiment, when stacking the barrels 1, any one barrel 1 can cooperate with the other four identical barrels 1 to form a single-layer structure. Furthermore, this application achieves the cooperation of the fixing plate 5 and the fixing hole 3 by opening an arc groove on the barrel wall, thereby maximizing the utilization of the lateral space. When utilizing the longitudinal space, one barrel 1 can be placed on top of another barrel 1, and the limiting block 8 of the upper barrel 1 is inserted into the top of the lower barrel 1. The bottom surface of the limiting block 8 of the upper barrel 1 is pressed against the top surface of the lid 7 of the lower barrel 1 to achieve lateral limiting and prevent lateral displacement.

[0040] Example 6: The difference between this example and Example 1 is that, as Figure 1 As shown, the lid 7 has two opening slots 6.

[0041] In this embodiment, the opening slot 6 is used to facilitate the operator to insert tools into the bucket lid 7, and then the opening slot 6 provides a force point to rotate the bucket lid 7 to open or close the storage bucket.

[0042] Example 7: The difference between this example and Example 2 is that, as Figure 2 As shown, the barrel body 1, barrel cover 7 and limiting ring 9 are all made of polyethylene. Polyethylene has a wide range of media resistance and high tensile strength and impact resistance, which can adapt to the transportation and operation environment of iron ion stabilizers for fracturing and acidizing.
