Abstract
Description
Technical Field
[0001] This utility model relates to the field of petroleum engineering technology, and in particular to an air foam oil displacement corrosion detection device that is easy to collect. Background Technology
[0002] Air foam flooding technology is a method to enhance oil recovery. By injecting foaming agents and foam stabilizers into the oil reservoir, gas and water are mixed to form a foam liquid, which improves the mobility ratio of the oil and thus enhances the recovery rate.
[0003] Currently, air foam flooding processes may introduce corrosive gases, such as oxygen, which can corrode injection and production pipelines and equipment, thus requiring corrosion testing. However, traditional methods for studying the corrosivity of air foam flooding agents involve manually brushing the agent onto a specialized testing plate. This method inevitably risks accidental skin contact with the agent, leading to injury and posing a safety risk. Furthermore, manual application makes it difficult to evenly distribute the agent on the testing plate, potentially affecting the testing results. Utility Model Content

A detection box is fixedly connected to the top outer wall of the workbench. A push frame and a liquid collection drawer are inserted into the detection box from top to bottom. A detection plate is fixed in the push frame by a centering locking mechanism. A reciprocating brushing mechanism is provided in the detection box.
[0007] The reciprocating coating mechanism includes a reciprocating lead screw rotatably installed in the detection box, a reciprocating slider adapted to be installed in the middle of the reciprocating lead screw, a hollow rod fixedly connected to one outer wall of the reciprocating slider, two mounting seats symmetrically fixed to the bottom outer wall of the hollow rod, a sponge coating brush roller rotatably installed on the two mounting seats, a liquid addition assembly, a guide assembly, and a drive assembly.
[0008] Preferably, the liquid addition assembly includes a liquid addition pipe fixedly connected to the top of the hollow rod and a funnel fixedly connected to the top of the liquid addition pipe. The top of the detection box is provided with a slide, and the outer wall of the liquid addition pipe is slidably connected to the inner wall of the slide.
[0009] Preferably, the guide assembly includes a guide block fixed to one outer wall of the hollow rod and a guide shaft welded inside the detection box, and the guide block and the guide shaft are slidably connected.
[0010] Preferably, the drive assembly includes a mounting cover fixedly connected to the side wall of the detection box, a drive motor fixedly mounted on one outer wall of the mounting cover, a driving bevel gear fixedly mounted on the output shaft of the drive motor, and a driven bevel gear fixedly mounted on one end of the reciprocating screw and meshing with the driving bevel gear, and the output shaft of the drive motor passes through one side of the mounting cover.
[0011] Preferably, the centering locking mechanism includes a groove formed on the inner wall of the bottom of the push frame, a bidirectional screw rotatably installed in the groove, two T-shaped locking rods symmetrically screwed to the two opposite threaded ends of the bidirectional screw, and a rotating cap fixedly connected to the outer wall of one end of the bidirectional screw, wherein the outer walls of the two T-shaped locking rods are slidably connected to the inner wall of the groove.
[0012] Preferably, the bottom of the hollow rod is provided with uniformly distributed drip holes, and the sponge applicator roller is in contact with the top surface of the detection plate.
[0013] The beneficial effects of this utility model are as follows:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 This embodiment discloses an air foam oil-displacement corrosivity detection device that is easy to collect, which includes a workbench 1 with braked casters fixedly installed at the four corners of the bottom, and a detection box 2 fixedly connected to the top outer wall of the workbench 1.
[0025] In this embodiment, a push frame 3 and a liquid collection drawer 4 are inserted into the test box 2 from top to bottom. The test plate 5 is fixed in the push frame 3 by a centering locking mechanism. A U-shaped handle is welded to the front outer wall of the liquid collection drawer 4. The material of the test plate 5 is usually aluminum sheet. This material is chosen because it can provide reliable corrosion data in the simulated corrosion environment. The test box 2 is equipped with a reciprocating brushing mechanism.
[0026] Specifically, the reciprocating coating mechanism includes a reciprocating screw 6 rotatably installed inside the detection box 2, a reciprocating slider 7 adapted to be installed in the middle of the reciprocating screw 6, a hollow rod 8 fixedly connected to one outer wall of the reciprocating slider 7, two mounting seats 9 symmetrically fixed to the bottom outer wall of the hollow rod 8, a sponge coating brush roller 10 rotatably installed on the two mounting seats 9, a liquid addition assembly, a guide assembly, and a drive assembly.
[0027] Furthermore, the bottom of the hollow rod 8 is provided with evenly distributed drip holes, and the sponge applicator roller 10 is in contact with the top surface of the detection plate 5.
[0028] Furthermore, the liquid filling assembly includes a liquid filling pipe 11 fixedly connected to the top of the hollow rod 8 and a funnel 12 fixedly connected to the top of the liquid filling pipe 11. A slide 21 is provided on the top of the detection box 2, and the outer wall of the liquid filling pipe 11 is slidably connected to the inner wall of the slide 21.
[0029] Furthermore, the guide assembly includes a guide block 13 fixed to one outer wall of the hollow rod 8 and a guide shaft 14 welded inside the detection box 2. The guide block 13 and the guide shaft 14 are slidably connected. In this way, the guide block 13 and the guide shaft 14 can ensure the stability of the reciprocating motion of the hollow rod 8 through the guiding cooperation.
[0030] Furthermore, the drive assembly includes a mounting cover 15 fixedly connected to the side wall of the detection box 2, a drive motor 16 fixedly mounted on one outer wall of the mounting cover 15, a driving bevel gear 17 fixedly mounted on the output shaft of the drive motor 16, and a driven bevel gear 18 fixedly mounted on one end of the reciprocating screw 6 and meshing with the driving bevel gear 17. The output shaft of the drive motor 16 passes through one side of the mounting cover 15.
[0031] Specifically, the centering locking mechanism includes a groove on the inner wall of the bottom of the push frame 3, a bidirectional screw 19 rotatably installed in the groove, two T-shaped locking rods 20 symmetrically screwed to the two opposite threaded ends of the bidirectional screw 19, and a rotating cap fixedly connected to the outer wall of one end of the bidirectional screw 19. The outer walls of the two T-shaped locking rods 20 are slidably connected to the inner wall of the groove.
[0032] The working principle of this embodiment is as follows: First, the detection plate 5 is placed in the push frame 3. Then, the bidirectional screw 19 is rotated by the rotating cap. Then, under the limit of the slide groove, the two T-shaped locking rods 20 that are threaded to the bidirectional screw 19 will be aligned and close together to lock the detection plate 5 in the push frame 3 to ensure the accuracy of the subsequent brushing work.
[0033] Next, push the push box 3 into the detection box 2. At this time, pour the prepared air foam oil repellent into the funnel 12. Then the air foam oil repellent will flow from the liquid filling pipe 11 into the hollow rod 8, and then drip from the evenly distributed dripping holes at the bottom of the hollow rod 8 into the sponge coating brush roller 10.
[0034] Next, the drive motor 16 drives the active bevel gear 17 to rotate, and then the driven bevel gear 18 meshing with the active bevel gear 17 drives the reciprocating screw 6 to rotate. Then, under the guidance of the guide assembly, the reciprocating slider 7 drives the sponge coating brush roller 10 at the bottom of the hollow rod 8 to roll back and forth on the surface of the detection plate 5. This not only effectively improves the safety of the detection process, but also allows the air foam oil repellent to be automatically and evenly applied to the detection plate 5, which facilitates the improvement of detection efficiency and effect.
[0035] Finally, by turning off the drive motor 16, pulling out the push frame 3, and observing the corrosion on the surface of the detection plate 5, the corrosion performance of the air foam oil repellent is determined. After the push frame 3 is pulled out, the residue dripped from the sponge application brush roller 10 can be collected by the liquid collection drawer 4.
[0036] 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.
