Description

Technical Field

[0001] The invention belongs to the technical field of reservoir structure simulation, in particular to a petroleum reservoir structure construction simulation device. Background Art

[0002] A petroleum reservoir is a rock layer containing recoverable oil and natural gas. Its structural configuration refers to the spatial distribution of physical parameters within the reservoir, such as lithology, porosity, permeability, pressure, and temperature. Research on the structural configuration of petroleum reservoirs is crucial for evaluating reservoir quality, optimizing development plans, and improving oil recovery. Using experimental materials and equipment to simulate and measure reservoir physical parameters yields experimental results that more realistically reflect the complex nonlinear factors within the reservoir and allow for intuitive observation and measurement of reservoir results.

[0003] Patent application number CN201410196269.1 discloses a device for simulating the construction of oil reservoir structures. This device comprises a physical simulation device consisting of a plexiglass box and a support frame that can be rotated 90 degrees and positioned. The plexiglass box is fixed on all four sides with two sides detachable and removable. It is equipped with several thin aluminum plates that can be bent into any desired shape. Electrodes with adjustable test heights are located at the bottom of the plexiglass box, while injection and production system ports are located on both sides of the box. The output ends of the electrodes are connected to a 24-core aviation plug via wires to serve as three-dimensional resistivity detection and monitoring ports. The thin aluminum plates are folded into various angles and arcs to simulate actual geological structures. After being squeezed and compacted, the plates are withdrawn, then reoriented and sealed with clay, vacuum grease, or the like before being recompacted.

[0004] However, it simulates the actual geological configuration by bending thin aluminum plates into various angles and arcs.

The vertical translation mechanism 2 drives the supporting frame 3 to translate up and down along the vertical centerline of the configuration simulation box 1.

[0050] The vertical distributing cylinder 6 is arranged just above the top opening of the configuration simulation box 1. The front and rear sides of the vertical distributing cylinder 6 are connected with a horizontal translation mechanism 5. The horizontal translation mechanism 5 drives the vertical distributing cylinder 6 to translate left and right along the horizontal center line of the configuration simulation box 1. The bottom end of the vertical distributing cylinder 6 is provided with a distributing opening 602. The upper end of the vertical distributing cylinder 6 is connected with a storage funnel 7.

A plurality of unit storage barrels 901 are evenly arranged in the horizontal direction in the middle of the horizontal storage rack 9. Sand particles and wax powder of various sizes are stored in the plurality of unit storage barrels 901. A quantitative conveying barrel 902 is provided at the bottom end of the unit storage barrel 901. A rotating conveying wheel 905 is provided in the middle of the quantitative conveying barrel 902 for rotation.

[0053] The horizontal heating rack 104 is symmetrically slidably arranged on the front and rear sides of the configuration simulation box 1 .

[0054] In this embodiment, the device stacks and fills sand particles of various sizes inside the configuration simulation box 1 to simulate the stratum of the corresponding oil reservoir, and the device transports and lays sand particles through the vertical distribution cylinder 6, and the horizontal translation mechanism 5 can drive the vertical distribution cylinder 6 to translate left and right along the horizontal center line direction of the configuration simulation box 1 to transport and lay sand particles to the corresponding position inside the configuration simulation box 1. At the same time, multiple unit storage cylinders 901 evenly arranged in the horizontal direction above the vertical distribution cylinder 6 respectively store sand particles of various sizes and wax powder. The barrel 6 can be moved to the bottom of the corresponding unit storage barrel 901, and then the rotating conveying wheel 905 in the quantitative conveying barrel 902 is driven to rotate by the conveying motor 907 connected to the shaft end, so that the multiple quantitative cavities 906 pass through the feeding opening 903 and the conveying opening 904 in turn, and then quantitatively convey the sand or wax powder required for filling to the storage funnel 7 below, and then the sand or wax powder in the storage funnel 7 is naturally conveyed to the distributing opening 602 along the vertical distributing barrel 6, and then after the vertical distributing barrel 6 moves to the corresponding position, the switch telescopic rod 60 The closed slide 603 is driven to slide open the material distribution opening 602, allowing sand or wax powder to be transported into the configuration simulation box 1 below, and then the required sand and wax powder are laid at the corresponding positions. All the laid sand or wax powder is constrained by the configuration simulation box 1 on all sides and supported by the supporting frame 3 at the bottom. At the same time, the vertical translation mechanism 2 drives the supporting frame 3 to translate up and down along the vertical centerline of the configuration simulation box 1. Therefore, the supporting frame 3 descends one level after each layer of sand is laid. By continuously laying multiple layers of sand and wax powder, a stratum simulating the corresponding oil reservoir can be stacked. After stacking is completed, the wax powder is heated by the horizontal heating frame 104 to melt and discharge, thereby forming an oil reservoir cavity of the desired shape. Liquid is then injected into the cavity to simulate the desired oil reservoir structure. The internal structure can be observed in real time through the transparent observation window 101, thereby horizontally dividing the stratum structure into multiple layers. By stacking layer by layer, a more complex oil reservoir structure model can be constructed, which is more flexible and convenient to use.

[0067] Working principle: Figure 1-11 As shown, when in use, first, the required sand particles and wax powder of various sizes are stored in the corresponding device unit storage barrels 901 according to the needs, then the supporting chassis 3 is kept at the top of the configuration simulation box 1, and the translation pulley 502 pulls the translation slider 601 to slide along the horizontal guide rail 501 through the traction belt 503, thereby driving the vertical distribution barrel 6 to translate left and right along the horizontal center line direction of the configuration simulation box 1, and move to the bottom of the unit storage barrel 901 loaded with the required sand particles and or wax powder;

[0068] Then, the rotating conveying wheel 905 in the quantitative conveying cylinder 902 is driven by the conveying motor 907 connected to the shaft end, so that the multiple quantitative cavities 906 pass through the feeding opening 903 and the conveying opening 904 in sequence, and then quantitatively convey the sand or wax powder required for filling to the storage funnel 7 below;

[0069] After the filling is completed, the vertical feeding cylinder 6 is moved to the corresponding position, and the switch telescopic rod 604 drives the closed slide 603 to slide and open the feeding opening 602, so that the sand or wax powder is transported to the interior of the configuration simulation box 1 below, and then the required sand and wax powder are laid at the corresponding position. Then the switch telescopic rod 604 drives the closed slide 603 to slide and re-close the feeding opening 602, and the unloading motor 706 can drive the unloading push plate 703 to move forward through the unloading gear 705 and the unloading rack 702 to push the remaining sand and wax powder in the storage funnel 7 and the vertical feeding cylinder 6, and push the unloading sealing plate 803 forward through the linkage push rod 704 provided on the front side to open the unloading opening 8, thereby facilitating the discharge of excess sand and wax powder from the unloading opening 8 along the inclined guide plate 801 into the edge collecting trough 102;

[0070] Then the filling is refilled and the laying work is carried out. After completing one layer of laying by cycling the above steps, the lifting stepper motor 206 can drive the lifting screw sleeve 203 to rotate through the driving gear 205 and the screw sleeve gear 204, and then the lifting screw 202 is used to pull the supporting frame 3 up and down, so that the supporting frame 3 will drop one layer of height every time a layer of sand is laid. By continuously cyclically laying multiple layers of sand and wax powder, a stratum simulating the corresponding oil reservoir can be stacked. The horizontal heating frame 104 drives the horizontal heating pipe 106 to move up and down to evenly heat the wax powder inside the configuration simulation box 1, so that the wax powder therein is melted and discharged, and then all the switch solenoid valves 303 are closed, and the booster delivery pump 305 and the delivery hose 304 are used to deliver the simulated oil liquid into the simulated cavity left after the wax powder is heated and discharged, thereby simulating the required oil reservoir structure configuration.

[0073] Sand particles and wax powder of various sizes are stored in a plurality of unit storage barrels 901 respectively, and then the vertical distributing barrel 6 is driven by the horizontal translation mechanism 5 to translate left and right along the horizontal center line direction of the configuration simulation box 1 to move to the bottom of the corresponding unit storage barrel 901, and then the rotating conveying wheel 905 in the quantitative conveying barrel 902 is driven to rotate by the conveying motor 907 connected to the shaft end, so that the plurality of quantitative cavities 906 pass through the feeding opening 903 and the conveying opening 904 in turn, and then quantitatively convey the sand particles or wax powder required for filling to the storage funnel 7 below, and then the sand particles or wax powder in the storage funnel 7 are naturally conveyed to the distributing opening 602 along the vertical distributing barrel 6, and then after the vertical distributing barrel 6 moves to the corresponding position, the switch telescopic rod 604 drives the closing slide 6 03 Slide open the fabric opening 602 to transport sand or wax powder to the interior of the configuration simulation box 1 below, and then lay the required sand and wax powder at the corresponding position. At the same time, the vertical translation mechanism 2 drives the supporting frame 3 to translate up and down along the vertical center line of the configuration simulation box 1. The supporting frame 3 drops one layer of height after laying each layer of sand. By continuously laying multiple layers of sand and wax powder in a cycle, they can be stacked to form a stratum that simulates the corresponding oil reservoir. After the stacking is completed, the wax powder is heated by the horizontal heating frame 104 to melt and discharge it, so as to form an oil reservoir cavity of the desired shape. Then, by injecting liquid into it, the desired oil reservoir structure configuration can be simulated. The internal structure can be observed in real time through the transparent observation window 101.

[0074] In summary, compared with the prior art, this application has the following beneficial effects:

[0075] The oil reservoir structure construction simulation device provided by the present application simulates the formation of the corresponding oil reservoir by stacking and filling sand particles of various particle sizes inside the configuration simulation box 1, and the device translates left and right along the horizontal center line of the configuration simulation box 1 through the vertical distribution cylinder 6 to transport the laid sand particles into the configuration simulation box 1. At the same time, multiple unit storage cylinders 901 arranged evenly in the horizontal direction above the vertical distribution cylinder 6 respectively store sand particles of various sizes and wax powder. The vertical distribution cylinder 6 can move to the bottom of the corresponding unit storage cylinder 901 and quantitatively transport the sand particles and wax powder required for filling through the quantitative delivery cylinder 902 to deposit the sand particles and wax powder at the corresponding position. The sand and wax powder required for laying are placed, and the supporting base frame 3 is lowered one level after each layer of sand is laid. By continuously circulatory laying of multiple layers of sand and wax powder, a stratum simulating the corresponding oil reservoir can be stacked to form a stratum. After the stacking is completed, the wax powder is heated by the horizontal heating frame 104 to melt and discharge it, so as to form an oil reservoir cavity of the required shape. Then, liquid is injected into it to simulate the required oil reservoir structure configuration. By dividing the stratum structure horizontally into multiple layers and stacking them layer by layer, a more complex oil reservoir structure configuration model can be formed, and the simulation flexibility and realism during use are higher.
