Description

Technical Field

[0001] This utility model relates to the field of oilfield acidizing fluid detection technology, and in particular to an oilfield acidizing fluid detection device. Background Technology

[0002] Acidifying fluids, prepared by mixing hydrochloric acid, hydrofluoric acid, acetic acid, corrosion inhibitors, drainage aids, and other components according to the required proportions and quantities, are commonly used in acidizing or fracturing operations of oil and water wells in various oilfields across China. They utilize the chemical reaction between the acid and rocks, blockages, and organic matter to dissolve blockages, clear formations, establish seepage channels, and increase oil well production and water injection volume. During the production of acidifying fluids in oilfields, it is necessary to test their quality. Testing determines the concentration of each component (such as hydrochloric acid and hydrofluoric acid) in the acidifying fluid, thereby assessing its suitability.

[0003] When testing oilfield acidizing fluid, multiple test bottles containing the fluid are first placed inside multiple clamping mechanisms to hold and secure them. The caps are then tightened, and multiple motors are started. The rotation of the motor outputs causes the test bottles to rotate through the clamping mechanisms, thoroughly mixing the fluid to ensure accurate testing. Once mixed, the motors are turned off, the bottle caps are opened, and various chemical reagents are added to each bottle to test the concentration of each component (such as hydrochloric acid and hydrofluoric acid) in the acidizing fluid, thereby assessing whether the acidizing fluid is qualified.

[0004] Multiple motors drive multiple test bottles to rotate and oscillate. Due to the large number of power sources, too much electrical energy is consumed, which is not energy-efficient. Utility Model Content

A connecting plate is fixedly connected to the surface of the limiting cylinder through a connecting column. A threaded rod is threadedly connected to the surface of the connecting plate.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: an oilfield acidizing fluid detection device, including a platform 1, a motor 2 mounted on the surface of the platform 1, the output end of the motor 2 passing through a shaft hole opened on the surface of the platform 1 and fixedly connected to a lead screw 3, a lifting block 4 threadedly connected to the surface of the lead screw 3, a plurality of hinge plates 5 hinged to the surface of the lifting block 4, a plurality of sliding grooves 6 fixedly connected to the lower surface of the platform 1, a slider 7 slidably connected inside the sliding grooves 6, the slider 7 being hinged to one end of the hinge plate 5, a rack 8 fixedly connected to one end of the slider 7 via a connecting rod, a plurality of rotating shafts 9 rotatably connected to the surface of the platform 1, a clamping mechanism 10 fixedly connected to the upper end of the rotating shaft 9, a gear 11 fixedly connected to the lower end of the rotating shaft 9, the gear 11 meshing with the rack 8.

[0020] In this implementation scheme, firstly, multiple test bottles containing oilfield acidizing fluid are placed inside each clamping mechanism 10 and fixed in place by the clamping mechanism 10. Then, the bottle caps are tightened, and the motor 2 is started. The output end of the motor 2 rotates, causing the lead screw 3 to rotate, which in turn causes the lifting block 4 to rise and fall. As the lifting block 4 rises and falls, multiple hinge plates 5 simultaneously drive multiple sliders 7 to slide inside the slide groove 6. The hinge plates 5 rotate relative to the lifting block 4. The movement of the sliders 7 causes the rack 8 to move. The rack 8, through meshing, drives the gear 11 to rotate, thereby driving the clamping mechanism 10 via the rotating shaft 9. The motor 2 rotates, which in turn drives the test bottle containing the oilfield acidizing fluid to rotate. When the lifting block 4 moves to the end of the lead screw 3, the motor 2 reverses, causing the test bottle to reverse. Therefore, the test bottle can be shaken in both directions to be evenly mixed. After it is evenly mixed, the motor 2 is turned off, the cap of the test bottle is opened, and then each chemical reagent is added into the inside of each test bottle to detect the concentration of each component in the oilfield acidizing fluid, such as hydrochloric acid and hydrofluoric acid, and to evaluate whether the acidizing fluid is qualified. By setting up one motor 2, multiple test bottles can be driven to rotate in both directions, thereby rotating and shaking multiple test bottles simultaneously, which reduces the power source and saves electricity.

[0021] Specifically, the clamping mechanism 10 includes a limiting cylinder 101. The upper end of the rotating shaft 9 is fixedly connected to the limiting cylinder 101. A connecting plate 102 is fixedly connected to the surface of the limiting cylinder 101 through a connecting post. A threaded rod 103 is threadedly connected to the surface of the connecting plate 102. One end of the threaded rod 103 is rotatably connected to a clamping plate 104. A limiting rod 105 is fixedly connected to the surface of the clamping plate 104. The limiting rod 105 passes through the connecting plate 102 and is slidably connected to the connecting plate 102.

[0022] In this embodiment, the test bottle is first placed inside the limiting cylinder 101, and then the threaded rod 103 is rotated, so that the clamping plate 104 moves and moves closer to the test bottle. At the same time, the limiting rod 105 slides on the surface of the connecting plate 102 until the clamping plate 104 presses the test bottle against it, so that the test bottle can be clamped and fixed.

[0023] Specifically, an anti-slip rubber pad is fixedly connected to one end of the clamping plate 104.

[0024] In this embodiment, by fixing an anti-slip rubber pad to one end of the clamping plate 104, the static friction coefficient between the clamping plate 104 and the test bottle during clamping can be increased, thereby providing a better fixing effect on the test bottle.

[0025] Specifically, a rotating knob 106 is fixedly connected to one end of the threaded rod 103.

[0026] In this embodiment, the user can rotate the threaded rod 103 by turning the rotating knob 106, thereby clamping the test bottle and making it convenient for the user to use the clamping mechanism 10.

[0027] Specifically, the surface of platform 1 is connected to multiple placement disks 12.

[0028] In this embodiment, by connecting multiple placement trays 12 to the surface of the platform 1, the user can place the testing instrument inside the placement tray 12. The placement tray 12 serves as a limit to prevent the testing instrument from rolling and falling to the ground.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
