[0002] Displacement flow apparatus is an experimental device used to simulate and study the seepage characteristics of oil reservoirs. It is widely used in petroleum, chemical and environmental science fields. Through equipment such as constant temperature chambers, the seepage environment of rock sample formation can be reproduced to a large extent, thereby simulating data such as rock sample permeability and porosity.
[0003] When conducting displacement experiments, the rock sample needs to be placed in a cylindrical holder, and then the holder is installed in a heating device. The two ends of the holder are connected to the input and output devices of the displacement fluid and kept sealed. Existing displacement devices mainly install the holder manually, which is not only inefficient, but also has poor stability during installation. Vibration and bumps during manual installation can cause the internal rock sample to shift, resulting in errors in the test results. Utility Model Content

[0024] 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. Example 1
[0025] Please refer to the appendix. Figure 1-6 It includes a constant temperature chamber 1 and a rock sample holder 4. The constant temperature chamber 1 is equipped with a displacement fluid inlet pipe 6 and a displacement fluid outlet pipe 7. It also includes a chamber cover 2, a mounting mechanism 3 and an automatic assembly mechanism 5, wherein:
[0026] The lid 2 is detachably installed on the upper end of the constant temperature chamber 1, and the lid 2 is provided with an installation port 22;
[0027] The installation mechanism 3 includes an installation basket 32 that is movably connected to the installation port 22, and a rock sample holder 4 is placed on the installation basket 32.
[0028] The automatic assembly mechanism 5 includes symmetrically arranged connecting conduits 55 that can move laterally via cylinders 51. The connecting conduits 55 are respectively installed and connected to the displacing fluid input pipe 6 and the displacing fluid output pipe 7. The connecting conduits 55 correspond to and cooperate with the two ends of the rock sample holder 4.
[0029] Please refer to the appendix. Figure 1-2 The cover 2 is connected to the constant temperature box 1 by multiple mounting bolts 21. The top of the mounting basket 32 is equipped with a sealing cover 31 that can close the mounting opening 22, and a handle 34 is installed on the top of the sealing cover 31.
[0030] Specifically, the handle 34 facilitates the insertion and removal of the installation basket 32, and the sealing cover 31 can seal the installation port 22 to isolate it from the outside world, thus avoiding affecting the temperature inside the constant temperature chamber 1.
[0031] Please refer to the appendix. Figure 3 The upper end of the installation basket 32 is equipped with multiple equally spaced clamping plates 33. The upper end of the clamping plate 33 is provided with a clamping groove 331. The bottom of the rock sample holder 4 is symmetrically equipped with foot plates 41 that can be inserted into the clamping groove 331. The clamping groove 331 and the foot plate 41 are movably connected and cooperate.
[0032] Furthermore, a placement rack 23 corresponding to the installation port 22 is installed at the bottom of the box cover 2. The installation basket 32 is movably connected to and fits the placement rack 23, and the connecting conduit 55 is movably connected to the left and right sides of the placement rack 23.
[0033] Specifically, the rock sample holder 4 can be fixed to the upper end of the installation basket 32 by the cooperation of the clamping plate 33 and the foot plate 41, so as to prevent the rock sample holder 4 from shaking and shifting when it is placed into the installation basket 32, which would prevent it from being properly connected to the connecting conduit 55.
[0034] It is important to note that the rock sample holder 4 should be placed centered on the upper end of the mounting basket 32 to ensure that the connecting tubes 55 at both ends can be properly inserted into the rock sample holder 4 and connected to it under the drive of the cylinder 51. If it is not placed centered, one side of the rock sample holder 4 will not be able to connect to the connecting tube 55.
[0035] Please refer to the appendix. Figure 4 A cylinder 51 is symmetrically installed inside the constant temperature chamber 1. The output end of the cylinder 51 is fixedly connected to the connecting tube 55. A sealing rubber ring 53 is installed at the end of the connecting tube 55. The rock sample holder 4 has sealing grooves 42 symmetrically provided at both ends to cooperate with the sealing rubber ring 53.
[0036] In this embodiment, the cylinder 51 drives the connecting conduit 55 to move horizontally, so that the connecting conduit 55 connecting the displacement fluid input pipe 6 and the displacement fluid output pipe 7 is sealed and connected to the rock sample holder 4 through the sealing groove 42 and the rubber sealing ring. Example 2
[0037] Based on the above embodiment one, please refer to the appendix. Figure 5 The placement frame 23 has guide cylinders 52 symmetrically installed at both ends, and a guide plate 54 is installed on the outer wall of the connecting tube 55. The guide plate 54 is movably connected to and fits the guide cylinder 52.
[0038] Furthermore, the displacing fluid inlet pipe 6 and the displacing fluid outlet pipe 7 are both connected to the bottom of the connecting conduit 55. The bottom of the guide cylinder 52 is provided with a movable groove 521 for the displacing fluid inlet pipe 6 and the displacing fluid outlet pipe 7 to move. A retractable double-layer telescopic hose 61 is installed in the middle of the displacing fluid inlet pipe 6 and the displacing fluid outlet pipe 7.
[0039] In this embodiment, the guide plate 54 and guide cylinder 52 can restrict the movement path of the connecting conduit 55, so that the connecting conduit 55 always remains horizontal when it is installed and extended, and will not deviate, thus improving the accuracy of the rock sample holder 4 during installation. At the same time, the movable groove 521 will not affect the movement of the displacement fluid input pipe 6 and the displacement fluid output pipe 7.
[0040] The working principle and usage process of this utility model are as follows: The rock sample holder 4 with the foot plate 41 is placed in the center on the upper end of the installation basket 32 with the side facing down. The foot plate 41 at the bottom of the rock sample holder 4 is locked in the slot 331 on the card plate 33 to keep the rock sample holder 4 in a fixed position. Then, the installation basket 32 is placed into the installation opening 22. The installation basket 32 passes through the installation opening 22 and enters the constant temperature chamber 1. After the installation basket 32 is completely entered into the constant temperature chamber 1, the sealing cover 31 at the upper end of the installation basket 32 is attached to the surface of the chamber cover 2 to seal the installation opening 22.
[0041] Start cylinder 51. Cylinder 51 drives two connecting tubes 55, which are connected to the displacing fluid inlet pipe 6 and the displacing fluid outlet pipe 7, to move from both sides toward the sealing grooves 42 on both sides of the rock sample holder 4. During this process, the connecting tubes 55 drive the guide plate 54 to move inside the guide cylinder 52. The guide cylinder 52 guides the movement path of the guide plate 54, keeping the guide plate 54 moving in a straight line, and thus guiding the connecting tubes 55 so that the connecting tubes move in a straight line without deviating. The output length of cylinder 51 is adapted to the length of rock sample holder 4. Under the action of cylinder 51, the sealing rubber ring 53 on the connecting tube 55 is inserted into the sealing groove 42 and connected to the rock sample holder 4, completing the installation.
