[0023] The drilling plugging simulation test device includes a constant pressure pump, a piston container, a square circulation pipeline, a formation model, a buffer container, a back pressure valve and an electronic balance which are connected in sequence through pipelines. The high-pressure circulation pump is used to drive the flow of drilling fluid in the square circulation pipeline to simulate the upward and backward flow rate of the drilling fluid in the formation, so that the plugging test is closer to the plugging site, and thus more realistic and reliable test results can be obtained. However, the simulation test device is not easy to move, and the simulation test device occupies a large area, is not easy to repair and replace, has certain limitations, and is not convenient to use.

[0024] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a drilling plugging simulation test device. When it is needed, it is only necessary to turn on the dual-axis motor 21 and adjust the position between the mounting plate 11 and the mounting plate 2 12, so as to achieve quick disassembly between the boosting mechanism 13, the cylinder 14 and the plugging liquid container 15, which is more convenient and quick, and improves the convenience of the device.

[0025] The present application is described below with reference to the accompanying drawings and specific embodiments: Combination Figure 1-Figure 4 The embodiment of the present application provides a drilling plugging simulation test device, including a test component 1; the test component 1 includes: a mounting plate 11 with mounting plates 12 on both sides; a booster mechanism 13 is plugged into the top of one of the mounting plates 12; a plugging liquid container 15 is plugged into the top of another mounting plate 12; a cylinder 14 is plugged into the top of the mounting plate 11; a mounting groove 16 is opened at the top of the mounting plate 11 and the mounting plate 2, and the booster mechanism 13, the cylinder 14 and the plugging liquid container 15 are respectively inserted into one of the mounting grooves 16, and a magnetic attraction mechanism is arranged between the mounting grooves 16; an adjustment component 2 is arranged on the mounting plate 11; the adjustment component 2 includes: a dual-axis motor 21 is fixedly connected to Connected to the mounting plate 11; the threaded rod 22 is fixedly connected to the output end of the dual-axis motor 21 and is rotationally connected to the mounting plate 11; the slider 23 is slidably connected to the mounting plate 11 and is threadedly connected to the threaded rod 22; the push plate 24 is fixedly connected to the slider 23, and the two push plates 24 are respectively fixedly connected to the two mounting plates 12; the connecting plate 25 is slidably connected in the mounting plate 11, and the two connecting plates 25 are respectively fixedly connected to the two mounting plates 12; the mounting seat 26 is fixedly connected to the mounting plate 12 and the top of the mounting plate 11, and a sealing component 3 is provided between the boosting mechanism 13 and the cylinder 14 and between the cylinder 14 and the plugging liquid container 15.

[0026] When in use, after installing the mounting plate 1 11 and the mounting plate 2 12 at the designated position, the boosting mechanism 13, the cylinder 14 and the plugging liquid container 15 are connected with the cooperation of the sealing component 3, and a heating rod is arranged in the cylinder 14, and the boosting mechanism 13 and the heating rod are started by manual control, the boosting mechanism 13 is a boosting pump and a connecting pipeline, simulating the high pressure and high temperature conditions inside the drilling well, and a leakage pipe is arranged on the cylinder 14, and a solenoid valve is arranged in the leakage pipe, and the leakage condition is simulated by opening or closing the solenoid valve, and the bottom of the mounting plate 1 11 and the mounting plate 2 12 are provided with moving wheels 17, which is convenient for moving the entire equipment. When disassembly and maintenance are required, the simulation is stopped, and after the materials in the equipment are emptied, the dual-axis motor 21 is turned on so that its output end drives the threaded rod When 22 rotates, the slider 23 is threadedly connected to the threaded rod 22, so that the slider 23 pushes the push plate 24 to slide outward, and the two push plates 24 respectively push the two connecting plates 25 to slide out of the mounting plate 11. While sliding, the distance between the mounting seats 26 on the mounting plate 11 and the mounting plate 2 12 is increased, so that the sealing components 3 on the two adjacent mounting seats 26 are separated, and the booster mechanism 13 and the cylinder 14 are disassembled, or the cylinder 14 and the plugging liquid container 15 are disassembled, and then the booster mechanism 13, the cylinder 14 or the plugging liquid container 15 are slid out of the mounting groove 16. While sliding, the magnet in the mounting groove 16 is separated from the magnet on the booster mechanism 13, the cylinder 14 or the plugging liquid container 15, so that disassembly is achieved, and vice versa.

[0027] In some embodiments, the sealing assembly 3 includes: a pipe 31 is arranged on the boosting mechanism 13, the cylinder 14 and the plugging liquid container 15, and the boosting mechanism 13, the cylinder 14 and the plugging liquid container 15 are connected through the pipe 31; a ring body 1 32 is fixedly connected to one end of the pipe 31; a ring body 2 33 is fixedly connected to the outside of the ring body 1 32; a sealing ring 1 34 is arranged on the outside of the ring body 1 32; a ring body 35 is fixedly connected to the outside of another pipe 31; a sealing ring 2 36 is arranged on the inside of the ring body 35, and the ring body 35 is inserted between the ring body 1 32 and the ring body 2 33.

[0028] When the two mounting seats 26 slide toward the back, a pipe 31 drives the ring body three 35 and the sealing ring two 36 to slide out from the ring body one 32 to achieve separation. Conversely, when the two mounting seats 26 approach, the ring body one 32 is inserted into the ring body three 35 and pressed against the sealing ring two 36. At the same time, the sealing ring two 36 is pressed against the sealing ring one 34 between the ring bodies one 32 and the ring bodies two 33, thereby achieving a double sealing effect.

[0029] In some embodiments, a sliding assembly 4 is provided on the second mounting plate 12; the sliding assembly 4 includes: a cavity 41 opened on the second mounting plate 12; an electric push rod 42 fixedly connected in the cavity 41; and a push block 43 fixedly connected to the output end of the electric push rod 42.

[0030] When in use, turn on the electric push rod 42 so that its output end pushes the push block 43 to slide downward from the cavity 41, so that the push block 43 props up the device and the moving wheel 17 is separated from the ground, which has a good supporting effect on the simulation experiment device and is convenient for subsequent installation or disassembly.

[0031] In some embodiments, the sliding components 4 are provided in multiple groups, and the multiple groups of sliding components 4 are used simultaneously to share the gravity and increase the service life.

[0032] In some embodiments, a limiting assembly 5 is provided on the mounting plate 12; the limiting assembly 5 includes: a limiting rod 51 slidably connected in the mounting plate 12; an adjusting block 52 is slidably connected to the mounting plate 12, and one end of the limiting rod 51 is fixedly connected to the adjusting block 52, and the other end of the limiting rod 51 is fixedly connected to the mounting plate 1 11.

[0033] During use, when the mounting plate 12 slides, the limit rod 51 slides horizontally in the mounting plate 12, driving the adjusting block 52 to slide horizontally. When the mounting plate 12 slides in the direction close to the mounting plate 11, the adjusting block 52 moves away from the mounting plate 11. At this time, the moving wheel 17 is always in contact with the ground. Conversely, when the mounting plate 12 slides in the direction away from the mounting plate 11, the adjusting block 52 pushes the pushing block 43, causing the pushing block 43 to slide out from the bottom of the mounting plate 12, so that the boosting mechanism 13 and the cylinder 14 are separated by the sealing assembly 3 or the cylinder 14 and the plugging liquid container 15 are separated by the sealing assembly 3. The pushing block 43 contacts the ground and plays a supporting role, thereby improving stability and facilitating subsequent disassembly.

[0034] In some embodiments, the push block 43 is provided with a chamfer to facilitate the adjustment block 52 to push the push block 43 .

[0035] In some embodiments, the adjustment block 52 is L-shaped, so that the adjustment block 52 can slide more stably in the mounting plate 12 .

[0036] In some embodiments, a housing 6 is fixedly connected to the mounting plate 11 to cover and protect the dual-axis motor 21 .

[0037] In some embodiments, the housing 6 is C-shaped to prevent the housing 6 from affecting the normal use of the slider 23 .

[0038] In some embodiments, the mounting seat 26 is fixed to the mounting plate 1 11 and the mounting plate 2 12 by bolts, so that the mounting seat 26 can be disassembled separately, thereby facilitating the separate disassembly of the boosting mechanism 13 , the cylinder 14 or the plugging liquid container 15 . In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
