Description

Technical Field

[0001] The utility model relates to the technical field of micro-nano displacing agents, in particular to a micro-nano displacing agent sampling and detection device. Background Art

[0002] Micro-nano displacement agent is an additive used to improve the recovery rate of crude oil during oil drilling and exploitation. The most commonly used is polymer-type oil displacement agent. For example, ultra-high molecular weight polyacrylamide, with a 0.05% aqueous solution, can penetrate into the oil layer rock gap and produce 20% to 30% more oil. Roughly, every 1kg of oil displacement agent can produce 10 barrels of more crude oil. The segmented oil displacement of polymer solution and surfactant (microemulsion composed of petroleum sulfonate and alcohol) can displace the crude oil in the capillary of the rock formation, with an effect of almost 100%.

[0003] When producing micro-nano displacing agents, there will be differences in the movement of internal components of displacing agents produced in different batches. In order to ensure that the product quality is qualified and meets production needs, it is necessary to conduct regular sampling and testing of the products during production.

[0004] The sampling method in the prior art adopts manual sampling, which is not only cumbersome, time-consuming and labor-intensive, but also the chemicals in the degreasing agent can enter the human body through inhalation, contact or accidental ingestion, causing discomfort symptoms such as eye stinging, headache, coughing, shortness of breath, nausea, vomiting, etc. Long-term contact may also induce allergic reactions, skin inflammation and other health problems.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

When the device is used to sample the displacing agent, the sampling plate is controlled to slide in the sliding groove of the fixing frame. When the sampling hole of the sampling plate moves to the bottom of the filling tube, part of the displacing agent will enter between the sampling tube and the baffle through the sampling hole. Then the sampling plate is controlled to reset so that the sampling tube moves out of the baffle part, and the displacing agent in the sampling tube will fall downward for sampling, so that the device can sample the displacing agent according to demand.

[0016] 2. The utility model is provided with components such as a motor, a transmission plate, a push rod and a push plate. When using the device, the motor is started by controlling the motor.

The push plate will push the sampling plate to one side through the guide column 2, and then the push rod will continue to rotate and contact the guide column 1. The push rod will help the sampling plate to reset through the guide column 1, and the spring and the limit rod will help the push plate to reset, so that the device can control the lateral movement of the sampling plate according to demand.

DETAILED DESCRIPTION

[0023] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0024] See also Figure 1 and Figure 2 The utility model discloses a micro-nano displacement agent sampling and detection device, comprising a filling tube 1. The inner bottom of the filling tube 1 can be designed horizontally. The horizontal design can facilitate the installation of a fixing frame 2 and the movement of a sampling plate 4 in the filling tube 1. Specifically, a fixing frame 2 is installed inside the filling tube 1. The fixing frame 2 can facilitate the installation of the sampling plate 4. A sliding groove 3 is provided inside the fixing frame 2. The sliding groove 3 can facilitate the horizontal movement of the sampling plate 4 in the fixing frame 2.

[0025] In a preferred embodiment, a sampling plate 4 is slidably connected to the inner wall of the sliding groove 3, and the micro-nano displacing agent in the filling tube 1 can be conveniently sampled by moving the sampling plate 4. Specifically, a sampling hole 5 is opened inside the sampling plate 4. When the sampling plate 4 moves and drives the sampling hole 5 to move to the inside of the filling tube 1, part of the displacing agent will enter the sampling tube 6 through the sampling hole 5. The lower end of the sampling hole 5 is fixedly connected to the sampling tube 6. The displacing agent entering the sampling tube 6 will be discharged from the lower end when the sampling plate 4 is reset. A storage container can be set below the sampling tube 6 to collect the displacing agent sample in the sampling tube 6. The bottom surface of the fixed frame 2 is fixedly connected to a baffle 21. The baffle 21 can be set to prevent the displacing agent inside the sampling tube 6 from leaking when the sampling tube 6 is located below the filling tube 1.

[0026] See also Figure 2 and Figure 4A fixing plate 10 is fixedly connected to the outer surface of the fixing frame 2. The setting of the fixing plate 10 can facilitate the installation of the motor 11, the fixing block 12 and the fixing block 2 16. Specifically, a motor 11 is fixedly installed on a side of the fixing plate 10 away from the fixing frame 2. The setting of the motor 11 can provide power for the connecting shaft 13. The output end of the motor 11 is fixedly connected to the connecting shaft 13. When the motor 11 is started, the connecting shaft 13 will be driven to rotate. A transmission plate 14 is fixedly connected to the outer surface of the connecting shaft 13. When the connecting shaft 13 rotates, the transmission plate 14 will be driven to rotate. A push rod 15 is fixedly connected to the end of the transmission plate 14 away from the motor 11. When the transmission plate 14 rotates, the push rod 15 will be driven to rotate.

[0027] See also Figure 2 and Figure 4 A fixed block 12 and a fixed block 2 16 are fixedly connected to a side of the fixed plate 10 away from the motor 11. The fixed block 12 and the fixed block 2 16 can be conveniently installed by the connecting shaft 13 and the connecting shaft 2 17. Specifically, the outer surface of the connecting shaft 13 is rotatably connected to the fixed block 12, and the internal rotation of the fixed block 2 16 is connected to the connecting shaft 2 17. The outer surface of the connecting shaft 2 17 is fixedly connected to the push plate 18. The push plate 18 can be conveniently installed and rotated by the connecting shaft 2 17. When the push rod 15 rotates, it will first contact the upper end of the push plate 18, and the push rod 15 will push the push plate 18 to rotate. The lower end of the push plate 18 will contact the guide column 2 9 and control the sampling plate 4 to move through the guide column 2 9.

[0028] In a preferred embodiment, the fixed block 16 is fixedly connected to a limiting column 19 on a side away from the fixed plate 10. The limiting column 19 can limit the angle of rotation of the push plate 18 to help the push plate 18 to reset. A spring 20 is installed on the outer surface of the connecting shaft 17. The spring 20 can help the push plate 18 to rebound and reset when the push rod 15 loses contact with the push plate 18.

[0029] See also Figure 3 and Figure 4 The bottom surface of the sampling plate 4 is fixedly connected with a guide column 7 and a connecting column 8. When the push rod 15 contacts the push plate 18, the push rod 15 will continue to rotate. At this time, the push rod 15 will contact the guide column 7 and control the sampling plate 4 to reset by contacting the guide column 7. The setting of the connecting column 8 can facilitate the installation of the guide column 2 9. The outer surface of the connecting column 8 is fixedly connected with the guide column 2 9. The installed guide column 2 9 can cooperate with the push plate 18 to control the sampling plate 4 to move horizontally.
