Description

Technical Field

[0001] The present invention relates to the technical field of in-situ environment reconstruction, and particularly to a displacement system under the reconstruction of deep in-situ high-temperature and high-pressure environment. Background Art

[0002] The "in-situ" problem of deep rock mechanics is the theoretical basis for exploring deep resources. The key lies in obtaining a true-fidelity core under the deep in-situ environment and conducting a full-process true-fidelity test and analysis in the in-situ state. For the full-process true-fidelity test and analysis, the displacement system is a key system, which needs to enable different functional cabins maintaining the high-temperature and high-pressure in-situ state inside to complete precise and safe docking and separation. During the true-fidelity test process, the docking and separation of many different functional cabin segments are involved, and the true-fidelity cabins are all docked and separated while carrying the reconstructed environment.

[0003] At present, the in-situ environment reconstruction and true-fidelity test systems developed earlier by research institutions at home and abroad are all integrated test systems. The test system is relatively long, the system scalability is poor, and it is necessary to manually replace the functional cabin segments during the true-fidelity test process. Such in-situ environment reconstruction and true-fidelity test systems have low test accuracy and efficiency and are not applicable to high-temperature and high-pressure environments.

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0052] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, a shifting system under the reconstruction of a deep in-situ high-temperature and ultra-high-pressure environment provided by an embodiment of the present invention includes:

[0053] A base 100, on which a first displacement mechanism is provided for driving the cabins on the base 100 to move along the length direction of the base 100;

[0054] A plurality of bidirectional displacement mechanisms 200 for driving the cabins on the bidirectional displacement mechanisms 200 to move along directions perpendicular to and parallel to the length direction of the base 100;

[0055] A plurality of unidirectional displacement mechanisms 300 for driving the cabins on the unidirectional displacement mechanisms 300 to move along a direction perpendicular to the length direction of the base 100;

[0056] The hoop 400 is fixedly connected to the base 100 and is used for fixedly connecting the ends of each compartment to control the sealing and separation of each compartment.

[0057] In this embodiment, as Figure 2 shown, the displacement compartment 510 and the first push rod compartment 520 in the deep in-situ high-temperature and high-pressure environment reconstruction system are installed at one end of the base 100. The first displacement mechanism drives the displacement compartment 510 and the first push rod compartment 520 to move on the base 100. The bidirectional displacement mechanism 200 and the unidirectional displacement mechanism 300 are respectively located on both sides of the base 100. The second push rod compartment 580 is installed on the bidirectional displacement mechanism 200 on the side of the base 100. A bidirectional displacement mechanism 200 is also provided at the end of the base 100 away from the displacement compartment 510. The pressure valve 570 and the hoop 400 are installed on the bidirectional displacement mechanism 200 at the end of the base 100. The core-taking docking compartment 530 and the acoustic electromagnetic non-contact test compartment 540 are respectively installed on different unidirectional displacement mechanisms 300. The cutting and preparation compartment 550 and the third push rod compartment 560 are installed on the base 100, and the cutting and preparation compartment 550 and the third push rod compartment 560 are arranged in parallel. The cutting and preparation compartment 550 and the third push rod compartment 560 are located between the acoustic electromagnetic non-contact test compartment 540 and the end of the base 100. When performing different experimental operations, by controlling the movement of the first displacement mechanism, the bidirectional displacement mechanism 200, and the unidirectional displacement mechanism 300, the connection of multiple compartments in the displacement compartment 510, the first push rod compartment 520, the core-taking docking compartment 530, the acoustic electromagnetic non-contact test compartment 540, the cutting and preparation compartment 550, the third push rod compartment 560, the pressure valve 570, and the second push rod compartment 580 is controlled. When connecting, the required compartments are displaced to be collinearly arranged on the base 100. At the same time, the hoop 400 fixedly connects different compartments, thereby realizing different operation processes.

[0058] The displacement system under the deep in-situ high-temperature and high-pressure environment reconstruction disclosed in the embodiment of the present invention realizes the precise displacement and docking of different compartments by setting the first displacement mechanism, the bidirectional displacement mechanism 200, and the unidirectional displacement mechanism 300 on the base 100, and seals and connects each compartment through the hoop 400, realizing the accuracy and efficiency of the environment reconstruction.

[0059] Specifically, as Figure 2 shown, when the displacement system works and controls the movement of each compartment, the following functions are realized:

[0060] Place the core sampler containing the in-situ environment-preserved core in the core sampling docking module 530. Connect the one-way displacement mechanism 300 of the core sampling docking module 530 to control the movement of the core sampling docking module 530, so that the core sampling docking module 530 is docked with the pressure valve 570 connected to the connecting and shifting module 510. The clamps 400 on both sides of the pressure valve 570 are tightened to form an integral body of the shifting module 510 - the first push rod module 520 - the clamp 400 - the pressure valve 570 - the clamp 400 - the core sampling docking module 530. Inject water into the inside of the shifting module 510 and the entire core sampling docking module 530 through the temperature and pressure control structure connected by the shifting module 510, and then perform in-situ environment reconstruction by heating and pressurizing. When the temperature and pressure environment inside the system is reconstructed to the in-situ temperature and pressure environment where the core is located, the temperature and pressure control system automatically stops heating and pressurizing and maintains the temperature and pressure environment inside the system at this time.

[0061] Core grabbing process; after the temperature and pressure control system reconstructs the in-situ temperature and pressure environment and maintains it in this temperature and pressure environment, operate the push rod system to extend the push rod with a core grabbing mechanism at its head inside the first push rod module 520. The push rod in the first push rod module 520 passes through the shifting module 510 and the pressure valve 570 in sequence and reaches the designated position in the core sampling docking module 530. The core grabbing mechanism grabs the core, and then drives the push rod in the first push rod module 520 to retract through the push rod system and pulls the core into the shifting module 510. Close the pressure valve 570 to make the core always in the in-situ temperature and pressure environment in the shifting module 510 and separate from the environment of the core sampling docking module 530. The temperature and pressure control system controls the core sampling docking module 530 to relieve pressure. After the pressure relief is completed, the clamp 400 connected to the core sampling docking module 530 is opened, and the one-way displacement mechanism 300 controls the separation of the core sampling docking module 530 from the remaining components including the first push rod module 520, the shifting module 510, two clamps 400, and the pressure valve 570. The one-way displacement mechanism 300 connected to the acoustic electromagnetic non-contact testing module 540 controls the movement of the acoustic electromagnetic non-contact testing module 540 onto the moving base 100. The first displacement mechanism located on the base 100 controls the movement of the first push rod module 520, the shifting module 510, two clamps 400, and the pressure valve 570 on the base 100 until the clamp 400 is connected to the acoustic electromagnetic non-contact testing module 540.

[0062] For acoustic electromagnetic non-contact testing, the temperature and pressure control system is reconstructed to the in-situ temperature and pressure environment where the core is located. Then, the temperature and pressure increase are automatically stopped, and the temperature and pressure environment is maintained. The pressure valve 570 is opened to make the internal environment of the new whole including the acoustic electromagnetic non-contact testing chamber 540 communicate. The push rod system makes the push rod of the first push rod chamber 520 drive the core to shift. The core is pushed to the designated testing position in the acoustic electromagnetic non-contact testing chamber 540. After the acoustic electromagnetic non-contact testing chamber 540 completes non-contact tests such as acoustic method, electrical method, and magnetic method, the push rod of the first push rod chamber 520 drives the core to retract into the shifting chamber 510. Then, the pressure valve 570 is closed to isolate the environment of the shifting chamber 510 from that of the acoustic electromagnetic non-contact testing chamber 540. Then, the pressure on one end of the acoustic electromagnetic non-contact testing chamber 540 is relieved. After complete pressure relief, the hoop 400 connected to the acoustic electromagnetic non-contact testing chamber 540 is opened, and the cabin docking system is controlled to separate the acoustic electromagnetic non-contact testing chamber 540 from the whole including the first push rod chamber 520, the shifting chamber 510, the hoop 400, and the pressure valve 570.

[0063] A standard core is prepared by cutting. The first displacement mechanism controls the movement of the whole including the first push rod chamber 520, the shifting chamber 510, the hoop 400, and the pressure valve 570 to dock it with the cutting and preparation chamber 550. The cutting and preparation chamber 550 is automatically docked with the pressure valve 570 on its right side, and the hoop 400 on the right side of the cutting and preparation chamber 550 is tightened to form a whole of the first push rod chamber 520 - shifting chamber 510 - hoop 400 - pressure valve 570 - hoop 400 - cutting and preparation chamber 550 - hoop 400 - pressure valve 570 - hoop 400 - pressure testing chamber 590. The temperature and pressure control system is reconstructed to the in-situ temperature and pressure environment where the core is located. Then, the temperature and pressure increase are automatically stopped, and the temperature and pressure environment is maintained. The pressure valve 570 is opened to make the internal environment of the new whole communicate. Then, the push rod system is operated to control the push rod of the first push rod chamber 520 to push the core to the designated position inside the cutting and preparation chamber 550. The cutting and preparation chamber 550 cuts the core into standard core specimens of 10 mm × 10 mm. After that, the push rod of the first push rod chamber 520 pulls the core back into the shifting chamber 510, the pressure valve 570 is closed to isolate the environment of the shifting chamber 510 from that of the cutting and preparation chamber 550. Then, the pressure on one end of the shifting chamber 510 is relieved alone. After the pressure is relieved to 0 MPa, the hoop 400 is opened, and the first displacement mechanism separates the shifting chamber 510 from the pressure valve 570. Then, the second push rod chamber 580 is accurately docked with the pressure valve 570 connecting the cutting and preparation chamber 550, and the hoop 400 is tightened.

[0064] The rock sample is displaced. The temperature and pressure environment at one end of the second push rod chamber 580 is reconstructed to be the same as that at one end of the cutting and preparation chamber 550. The pressure valve 570 is opened. The second push rod chamber 580 is operated to extend the push rod to push the standard core sample prepared in the cutting and preparation chamber 550 to the designated position in the pressure test chamber 590. Then, the push rod of the second push rod chamber 580 is controlled to retract to its original position, the pressure valve 570 is closed, and the environment in the pressure test chamber 590 is isolated from that in the cutting and preparation chamber 550. The temperature and pressure control system is operated to relieve the pressure in the cutting and preparation chamber 550. After the pressure relief is completed, the whole on the right side of the cutting and preparation chamber 550 is separated from the pressure test chamber 590. The bidirectional displacement mechanism 200 controls the whole including the hoop 400, the pressure valve 570, and the pressure test chamber 590 to be accurately docked with the third push rod chamber 560.

[0065] The pressure test chamber 590 is sealed. The temperature and pressure environment at one end of the third push rod chamber 560 is reconstructed to be the same as that at one end of the pressure test chamber 590. The pressure valve 570 is opened to make the environment in the third push rod chamber 560 communicate with that in the pressure test chamber 590. Then, the third push rod chamber 560 is operated to extend the push rod to push the sealing plug into the pressure test chamber 590 for sealing. Then, the third push rod chamber 560 is retracted to its original position. Then, the temperature and pressure control system is operated to relieve the pressure. The prepared standard core sample is sealed in the pressure test chamber 590 and maintained in the in-situ environment for subsequent placing the pressure test chamber 590 containing the core in the in-situ environment into a pressure testing machine to measure the physical and mechanical parameters of the real core.
