Description

Technical Field

[0001] This utility model relates to the field of petroleum sampling technology, specifically a petroleum extraction sample oil layer sampling device. Background Technology

[0002] Petroleum sampling refers to the process of collecting a small number of representative samples from various stages of petroleum production, storage, transportation, processing, or sales (including crude oil, refined oil, lubricating oil, and other petroleum products) according to specific technical specifications and procedures. These samples will be used for subsequent physical property analysis, chemical composition testing, quality evaluation, safety assessment, or compliance verification, and are a key link in the petroleum industry's quality control, safe production, and trade settlement.

[0003] An investigation revealed that a utility model patent (publication number: CN221628138U) discloses an oil well sampling device for oil extraction. The device includes a base plate with a sampling mechanism on top and a guide assembly on one side. During operation, the operator can activate a servo motor to release a first cable on a rotating column, allowing the sampling barrel to pass through the base plate and enter the oil well. Once the sampling barrel is submerged, the operator pulls a second cable, causing a limiting column and a fixing plate to rise, compressing a spring and allowing the bottom of the limiting column to enter the sampling barrel, thus allowing oil to enter. The operator then releases the second cable, releasing the spring pressure and returning the limiting column to its original position, sealing the bottom of the sampling barrel to prevent oil leakage. Reversing the servo motor raises the sampling barrel, and the operator can then pull the second cable again to release the oil from the sampling barrel, facilitating operation.

[0004] Although the aforementioned patent improves the stability and efficiency of the sampling process and enhances the accuracy of oil sampling through the arrangement of the sampling mechanism, base plate, and guiding components and the cooperation of various parts, the large number of components inside the sampling bucket to ensure that it can be opened at a designated level for easy sampling not only compresses the space inside the bucket, resulting in a small sampling volume, but also makes it difficult to completely sample the oil when taking it out of the bucket. This leaves residue inside the bucket that is difficult to clean, affecting multiple sampling uses and making it very inconvenient to improve sampling efficiency.

[0005] Therefore, this utility model provides an oil layer sampling device for oil extraction to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides an oil extraction sample collection device for oil reservoirs, aiming to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An oil extraction sample reservoir sampling device includes a frame and a sampling assembly, wherein the sampling assembly includes a retainer fixedly connected to the inner side wall of the frame; The sampling assembly includes a winch mounted on the top of a retainer. A take-up roller is coaxially driven at the output end of the winch. A rotating seat is fixedly connected to the top of the retainer. A sampling roll is rotatably connected to the inner wall of the rotating seat, and the sampling roll is rotatably sleeved on the end of the take-up roller. A sampling bucket is fixedly connected to the outer wall of the take-up roller via a stranded wire. A slide is fixedly connected to the outer wall of the sampling bucket. A slide rod is slidably connected to the inner wall of the slide. A sealing plug is fixedly sleeved on the outer wall of the slide rod, and the sealing plug abuts against the inner wall of the sampling bucket. The top of the slide rod is wound onto the outer wall of the sampling roll via a traction line.

[0008] As a preferred technical solution of this application, a partition plate is fixedly connected to the inner top of the sampling barrel, and a sealing cover is installed on the upper top of the sampling barrel above the partition plate.

[0009] As a preferred technical solution of this application, a micro motor is installed at the top of the sampling bucket inside the sealing cover, and a rotating rod is coaxially driven at the output end of the micro motor.

[0010] As a preferred technical solution of this application, the rotating rod passes through the partition plate and a baffle is fixedly sleeved at its end, and the outer wall of the baffle is in movable contact with the inner wall of the sampling barrel.

[0011] As a preferred technical solution of this application, a coaxial device is slidably connected to the outer wall of the sampling roll, and the coaxial device is inserted into the end of the take-up roller.

[0013] As a preferred technical solution of this application, a support plate is fixedly connected to the bottom end of the frame, and a caster wheel is installed at the bottom end of the support plate.

[0014] (III) Beneficial Effects 1. By designing the sampling assembly, the efficiency and accuracy of oil sampling can be improved through the cooperation of various components. Through the coordination of the sampling bucket, slide, slide rod, sealing plug, and traction line, the sampling bucket can quickly reach the sampling layer thickness using the counterweight plate. By releasing the traction line, the slide rod moves the sealing plug, thereby opening the inlet of the sampling bucket and allowing oil to quickly enter the bucket. Then, the traction line is wound up to seal the sampling bucket, and finally, the bucket is lifted to complete the sampling. This assembly has a simple structure and is highly practical. It can not only increase the single sampling volume, but also has sufficient space inside the bucket, which is convenient for operators to clean.

[0015] 2. By using a sampling cylinder in conjunction with a micro motor, a sealing cover, and internal partitions, rotating rods, and baffles, the sampling cylinder can achieve multi-layer sampling in a single operation through the cooperation of multiple components. After a single layer of sampling is completed, the sampling cylinder is lowered by continuing to lower the stranded wire. When the sampling point is reached again, the micro motor is activated to drive the baffles to rotate inside the sampling cylinder, causing the baffles to seal the oil sampled in the first operation. Then, the sampling work is completed again, thus achieving multi-layer sampling in a single descent. This component has a simple structure, high flexibility, and can improve sampling efficiency.

Detailed Implementation

[0018] 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.

[0019] This utility model provides a sample collection device for oil reservoirs in oil extraction, such as... Figures 1-4 As shown, the oil extraction sample reservoir sampling device includes a frame 1 and a sampling assembly. The sampling assembly includes a retainer 2 fixedly connected to the inner wall of the frame 1. The sampling assembly includes a winch 3 mounted on the top of the retainer 2. A take-up roller 4 is coaxially driven at the output end of the winch 3. A rotating seat 5 is fixedly connected to the top of the retainer 2. A sampling roll 6 is rotatably connected to the inner wall of the rotating seat 5, and the sampling roll 6 is rotatably sleeved on the end of the take-up roller 4. A sampling bucket 8 is fixedly connected to the outer wall of the take-up roller 4 through a stranded wire 7. A slide 9 is fixedly connected to the outer wall of the sampling bucket 8. A slide rod 10 is slidably connected to the inner wall of the slide 9. A sealing plug 11 is fixedly sleeved on the outer wall of the slide rod 10, and the sealing plug 11 abuts against the inner wall of the sampling bucket 8. The top of the slide rod 10 is wound onto the outer wall of the sampling roll 6 through a traction line 12.

[0020] A coaxial connector 18 is slidably connected to the outer wall of the sampling roll 6, and the coaxial connector 18 is inserted into the end of the take-up roller 4. A rotating handle is fixedly sleeved at the end of the sampling roll 6 away from the coaxial connector 18.

[0021] A counterweight plate 19 is installed inside the sealing plug 11, and a lifting ring 20 is fixedly connected to the top of the frame 1.

[0022] Specifically, the frame 1 provides sufficient support for oil sampling. The robust support of the frame 1 improves stability during the sampling process. The sampling components, through their coordinated operation, enhance sampling efficiency and flexibility, increasing the amount of sampled at one time while facilitating cleaning of the sampling container 8. During sampling, the winch 3 is activated, driving the take-up roller 4 at the output end to rotate, thus lowering the sampling roll 6. Upon reaching the sampling layer, the coaxial connector 18 on the outer wall of the sampling roll 6 is pulled out, separating the sampling roll 6 from the take-up roller 4. The unwinding operation is then performed manually by turning the handle. Since the outer wall of the sampling roll 6 is connected to a sliding rod via a traction line 12... 10. Therefore, when rotating, the sealing plug 11 at the end of the slide rod 10, in conjunction with the counterweight plate 19, can quickly move the sealing plug 11 away from the sampling bucket 8, allowing oil to enter the interior of the sampling bucket 8. After sampling is completed, the slide rod 10 is reversed by reversing the sampling roll 6, causing the sealing plug 11 to reseal the sampling bucket 8. Then, the coaxial cable 18 is inserted, and the winch 3 is started to raise the sampling bucket 8 to complete the sampling work. This component has a simple structure and strong practicality. It can increase the sampling space inside the sampling bucket 8 and increase the single sampling volume. At the same time, the sealing plug 11, which can slide a large range, can also facilitate the operator to clean the inside of the bucket after sampling, avoiding residual oil from affecting the accuracy of the next sampling data.

[0023] A partition plate 13 is fixedly connected to the inner top of the sampling bucket 8, and a sealing cover 14 is installed above the partition plate 13 at the upper top of the sampling bucket 8.

[0024] A micro motor 15 is installed at the top of the sampling bucket 8 inside the sealing cover 14, and the output end of the micro motor 15 is coaxially driven by a rotating rod 16.

[0025] The rotating rod 16 passes through the partition plate 13 and its end is fixedly sleeved with a baffle 17. The outer wall of the baffle 17 is in contact with the inner wall of the sampling bucket 8.

[0026] A support plate 21 is fixedly connected to the bottom of the frame 1, and a caster wheel is installed at the bottom of the support plate 21.

[0027] Specifically, the sampling bucket 8, in conjunction with the partition plate 13, micro motor 15, rotating rod 16, and baffle 17, allows for multi-layer sampling in a single operation, improving sampling efficiency and data accuracy. When multi-layer sampling is required, the sampling bucket 8 is lowered to the second sampling layer after the single sampling step. The micro motor 15 is then activated, using the rotating rod 16 at its output end to rotate the baffle 17. This, in conjunction with the partition plate 13, seals the sampled oil inside the bucket. The same sampling steps are then repeated to complete the second sampling. This component has a simple structure, high flexibility, reduces the labor intensity of operators, and achieves the effect of multi-layer sampling in a single operation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
