Abstract
Description
Technical Field
[0001] This invention relates to the field of structural deformation simulation experiment technology, and in particular to a syn-depositional structure simulation experiment device and a syn-depositional structure simulation experiment method. Background Technology
[0002] Syn-sedimentary structures, also known as syn-genetic or growth structures, refer to structures formed during sedimentation. The structural morphology of syn-sedimentary structures generally manifests as intra-basin faults, basin-marginal faults, and folding deformation. Syn-sedimentary structures are mainly developed at the boundaries of divergent plates and on the hanging wall of syn-sedimentary faults in rift basins with slight intra-plate deformation. Oil-generating depressions are oil and gas-bearing depressions within sedimentary basins, capable of accumulating industrial oil and gas. Oil-generating depressions are conducive to the accumulation, preservation, enrichment, and conversion of sedimentary organic matter into oil and gas, making them ideal sites for oil and gas generation. Oil-generating depressions typically possess abundant oil-generating strata and ample oil and gas sources.
[0003] Co-sedimentary structures are closely related to the development of oil-generating depressions, the distribution of reservoir facies zones, and the formation of hydrocarbon traps. Physical simulation experiments are indoor processes that physically simulate sediments, recreating the sedimentary conditions of natural sediments in the laboratory by simulating specific sedimentary conditions.
[0004] However, existing physical simulation experimental equipment has an overly simple structure and limited functionality, which cannot guarantee the accuracy of experimental results.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0043] This embodiment provides a syn-sedimentary structure simulation experimental apparatus, which can be used to conduct syn-sedimentary structure simulation experiments.
[0044] Figure 1 A schematic diagram of the syn-sedimentary structure simulation experimental apparatus provided in an embodiment of the present invention is shown. Figure 1 (The partition is not shown); Figure 2 A schematic diagram of the syn-sedimentary structure simulation experimental apparatus provided in an embodiment of the present invention is shown. Figure 2 (A partition is shown.) Reference Figure 1 and Figure 2 The syn-sedimentary structure simulation experimental device provided in this embodiment includes a sand box 100, a partition 200, and a pushing mechanism 300.
[0045] Specifically, the partition 200 is detachably installed in the sand box 100, dividing the sand box 100 into a first box 110 and a second box 120 in the direction of gravity. The partition 200 is provided with a sand passage, through which the first box 110 and the second box 120 can communicate. The pushing mechanism 300 includes a first pushing member 310 and a second pushing member 320 with a plate-like structure. The first pushing member 310 is movably installed in the sand box 100 parallel to the direction of gravity and in the pushing direction. The second pushing member 320 is parallel to and spaced apart from the first pushing member 310, and can move simultaneously with the first pushing member 310. The pushing direction is perpendicular to the direction of gravity. The first pushing member 310 can push against the simulated geological layer inside the first box 110 in the pushing direction, and the second pushing member 320 can push against the simulated sedimentary sand in the pushing direction, so that the simulated sedimentary sand enters the first box 110 from the sand channel and is deposited into the target simulated depression. Through the above configuration, the process of actual geological layers being compressed and deposited can be simulated, that is, the process of forming a syn-sedimentary structure.
[0046] More specifically, the syn-sedimentary structure simulation experimental apparatus also includes a drive mechanism 400. The output end of the drive mechanism 400 is arranged parallel to the pushing direction, and the first pushing member 310 is connected to the output end of the drive mechanism 400. The drive mechanism 400 can drive the first pushing member 310 to move in the pushing direction. In this embodiment, the drive mechanism 400 can be an electric cylinder in the prior art, and its output end is a push rod that can be connected to the first pushing member 310.
[0047] More specifically, the pushing mechanism 300 also includes a spacing control element 330. This spacing control element 330 is arranged parallel to the pushing direction and connects the first pushing element 310 and the second pushing element 320. Through this spacing control element 330, in the initial stage of the movement of the first pushing element 310, only a simulated geological layer compression process is performed; at this time, the partition 200 is not installed in the sand box 100. During this process, the second pushing element 320 first follows the first pushing element 310 to a preset position. The distance between this preset position and the starting position of the first pushing element 310 is the length of the spacing control element 330. It should be noted that after the second pushing element 320 has moved to the preset position, the first pushing element 310 can push against the simulated geological layer to form the target simulated depression. When the simulated geological layer forms a target simulated depression under the pushing action of the first pusher 310, the partition 200 is then installed in the sand box 100, and simulated sedimentary sand is added to the second box 120. At this time, the first pusher 310 is pushed again, and the first pusher 310 continues to squeeze the simulated geological layer. At the same time, the second pusher 320 pushes the simulated sedimentary sand into the first box 110 to carry out the deposition process in the target simulated depression, thus realizing the simulation of the formation of the same sedimentary structure.
[0048] It should be noted that the first pusher 310 is provided with a clearance groove, which is configured to avoid the partition 200 during the movement of the first pusher 310 in the pushing direction, so as to avoid interference.
[0049] More specifically, the length of the spacing control component 330 is adjustable and it can be detachably connected between the first pusher 310 and the second pusher 320 via a structure such as a snap-fit. The length of the spacing control component 330 can be adjusted according to the actual situation of the simulation experiment to ensure that a simulated geological layer with the same geological morphology as the actual geological morphology can be formed before the partition 200 is installed in the sand box 100.
[0050] Figure 3 This diagram illustrates the structure of a partition provided in an embodiment of the present invention. (Refer to...) Figure 3 In one embodiment, the sand passage includes a plurality of sand passage holes 210 arranged in a rectangular array. The simulated sedimentary sand can fall into the first housing 110 through the plurality of sand passage holes 210, and the plurality of sand passage holes 210 have the same diameter. With the above arrangement, when the second pusher 320 is driven by the first pusher 310 to advance at a constant speed along the pushing direction, the simulated sedimentary sand can fall evenly into the first housing 110.
[0051] Figure 4 A schematic diagram of another partition provided in an embodiment of the present invention is shown. (Refer to...) Figure 4In another embodiment, as the second pusher 320 moves away from its starting position along the pushing direction, the diameter of the plurality of sand-passing holes 210 arranged in a rectangular array on the partition 200 gradually increases; and / or, as the second pusher 320 moves away from its starting position along the pushing direction, the spacing between the plurality of sand-passing holes 210 arranged in a rectangular array on the partition 200 gradually decreases. With these settings, as the second pusher 320 advances at a constant speed along the pushing direction, the amount of simulated sedimentary sand falling into the first box 110 gradually increases.
[0052] In another embodiment, as the second pusher 320 moves away from its starting position along the pushing direction, the diameter of the plurality of sand-through holes 210 arranged in a rectangular array on the partition 200 gradually decreases; and / or, as the second pusher 320 moves away from its starting position along the pushing direction, the spacing between the plurality of sand-through holes 210 arranged in a rectangular array on the partition 200 gradually increases. With these settings, as the second pusher 320 advances at a constant speed along the pushing direction, the amount of simulated sedimentary sand falling into the first housing 110 can be gradually reduced.
[0053] Preferably, the sand box 100 is made of a visual material. This design allows operators to easily observe the morphology of the simulated geological layers, the formation of the simulated depression, and the deposition of the simulated sedimentary sand. In this embodiment, the sand box 100 can specifically be made of acrylic material.
[0054] This embodiment also provides a method for simulating syn-sedimentary structures. This method enables the simulation of syn-sedimentary structures based on the syn-sedimentary structure simulation apparatus provided in this embodiment.
[0055] The experimental method for simulating syn-sedimentary structures includes:
[0056] Step S10: Scale down the actual geological area to be analyzed and determine the size of the sand box 100.
[0057] Specifically, after step S10, the following steps are performed:
[0058] The sand material for the simulated geological layer is prepared according to the geological parameters of the actual geology to be analyzed. In this embodiment, the sand material for the simulated geological layer is specifically prepared according to parameters such as the plasticity of the actual geology to be analyzed and the internal friction force, so as to ensure that the simulated geological layer after laying can closely resemble the actual geology to be analyzed.
[0059] Step S20: Lay the simulated geological layer at the bottom of the sand box 100.
[0060] Step S30: After pushing the first pusher 310 against the simulated geological layer to form the target simulated depression, the partition 200 is set in the sand box 100 to divide the sand box 100 into a first box 110 and a second box 120.
[0061] Specifically, after step S30, the following steps are performed:
[0062] The simulated sedimentary sand was prepared based on the sedimentary parameters of the actual geological conditions to be analyzed. These sedimentary parameters can be obtained through experimental analysis and empirical evidence.
[0063] Step S40: Add the simulated sedimentary sand to the second box 120. At this time, the second pusher 320 can push the simulated sedimentary sand along the pushing direction under the drive of the first pusher 310, so that the simulated sedimentary sand enters the first box 110 from the sand channel and is deposited into the target simulated depression.
[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
