Description

Technical Field

[0001] This invention relates to the field of geological structure simulation technology, and in particular to an experimental apparatus and method for simulating strike-slip faults and sedimentary deformation processes. Background Technology

[0002] In the field of petroleum geological exploration, fault sealing has always been a popular and complex problem. Throughout a complex and lengthy geological history, an oil and gas basin undergoes multiple phases of tectonic movement, often accompanied by syn-sedimentation. During strike-slip tectonic movements, the intensity of syn-sedimentation directly affects the thickness of the overlying strata, which in turn affects the vertical propagation of strike-slip faults, thus influencing the vertical conduction of oil and gas. Therefore, accurate simulation of syn-sedimentation is crucial and necessary. However, current domestic and international simulations of syn-sedimentation processes primarily rely on artificial sand application, a method heavily influenced by human factors and highly unreliable.

[0003] In summary, there is an urgent need for a sandbox physical simulation experimental device that can meet the actual exploration needs and simulate strike-slip tectonics and sedimentation. Summary of the Invention

[0004] The purpose of this invention is to provide an experimental apparatus and method for simulating the depositional deformation process of strike-slip faults, so as to solve the problems existing in the prior art and enable different degrees and forms of strike-slip fault depositional simulation experiments as needed.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides an experimental device for simulating strike-slip fault depositional deformation processes, comprising a strike-slip simulation system and a control system. The strike-slip simulation system consists of two identical left and right parts, each including a rectangular steel frame. Two parallel toothless screws are mounted on the rectangular steel frame, with a lead screw connecting the two toothless screws. An experimental plate is connected above the two toothless screws via a ring-shaped buckle, and experimental materials are placed on the experimental plate. Brush-equipped flaps are welded to the lower sides of the experimental plates where they meet. Baffles are vertically welded to the upper edges of the other sides of the experimental plates. The lower part of the experimental plate is connected to its corresponding lead screw via a servo motor module. The speed and direction of movement of the experimental plate can be controlled by controlling the rotation speed and direction of the servo motor module. A water jet and a camera are movably mounted above the strike-slip simulation system. The control system controls and monitors the water jet, camera, and servo motor module. This invention employs a dual-panel independent design, allowing for the selection of the movable plate as needed. It provides a sedimentation simulation structure that conforms to actual sedimentation processes, such as river sedimentation and rainwater sedimentation. The nozzle opening and position can be adjusted to simulate different forms and degrees of sedimentation. The device also incorporates a camera for recording experimental data, whose position can be adjusted as needed for optimal image capture. Connected to a host control module, it allows for direct commands via the host interface, enabling automatic recording and increasing the reliability and convenience of data recording. The entire experimental setup is safe, reliable, highly accurate, easy to operate, easy to disassemble and clean, and inexpensive to produce.

[0007] Optionally, it also includes a basic equipment system and an experimental auxiliary system; the basic equipment system includes a bottom cylinder with an open top, and a water storage tank is fixedly installed on one side inside the bottom cylinder; the experimental auxiliary system includes experimental auxiliary system support frames symmetrically arranged on the top of both sides of the bottom cylinder, and multiple guide rods are slidably arranged between the two experimental auxiliary system support frames, with the camera installed on the guide rod on one side, and the water spray head installed on the other guide rods, the water spray head being connected to the water pump in the water storage tank through a water pipe; the slip-prone simulation system is fixedly installed inside the bottom cylinder, and the slip-prone simulation system is located below the guide rods.

[0008] Optionally, the control system includes a host computer and a measurement and control module electrically connected; the host computer is used to provide a host computer operation interface, display the current working status of the device and provide an operation command input window; the measurement and control module includes a programmable logic controller, an A / D converter and a D / A converter, and the servo motor module includes a first servo motor and a second servo motor respectively set on the left and right parts of the sliding simulation system, and the measurement and control module is connected to the camera, the water pump, the first servo motor and the second servo motor respectively through wires. The programmable logic controller (PLC) has a pre-installed control program. The operator inputs control commands through the host computer's interface. The digital signal output from the host computer is transmitted to the measurement and control module. The measurement and control module converts the digital signal from the host computer into an analog signal via a D / A converter and transmits it to each drive module. Each drive module operates according to the state required by the input command. Simultaneously, the measurement and control module receives the status signals from each drive module, converts the analog drive status signals into digital signals via an A / D converter, and transmits them to the host computer for real-time status display on the interface. The PLC in the measurement and control module has a pre-installed control program that controls the servo motor module, camera, and water pump in the following manner:

[0009] After the system is powered on, the motor automatically determines whether the left and right experimental boards are started simultaneously. Since the control methods for the left and right experimental boards are the same and independent, this description uses the left experimental board as an example. When the left experimental board is determined to be in a non-started state, the first servo motor remains stationary. If the left experimental board is determined to be in a started state, the axis motion initialization configuration begins, i.e., the first servo motor axis motion module clears errors and marks the coordinate zero point; the preset left experimental board motion time and speed parameters are read and assigned to the corresponding functional modules; the target distance is calculated and assigned to the next functional module, where target distance = speed * time; the calculated linear distance is converted to wheelbase; this wheelbase is assigned to the corresponding functional module to determine the relationship between the current distance to be traveled and zero: ①. Determine if the current distance to be traveled is greater than zero; if so, the servo motor rotates forward; ②. Determine if the current distance to be traveled is greater than zero; if not, then determine if the current distance to be traveled is less than zero; if so, the servo motor rotates in reverse; ③. Determine if the current distance to be traveled is greater than zero; if not, then determine if the current distance to be traveled is less than zero; if not, the servo motor remains stationary. During the operation of the first servo motor, it continuously determines whether the target point has been reached. If it has, the motor stops immediately; if it has not, the motor continues its original operation. If no motion time parameter is preset, the system defaults to an infinite time, requiring the operator to issue a stop command or cut off the power through the host computer interface to stop the motor. After the system is powered on, it checks whether the left and right experimental boards are started, and also whether the camera is turned on. If the camera is not turned on, it is not powered on. If the camera is turned on, it reads the preset photo interval parameter and assigns it to the corresponding functional module. The camera shutter is triggered once, and a photo is taken. Then the timing module starts working and assigns the value to the corresponding functional module in real time. It checks whether the servo motor has stopped. If it has, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and the camera is powered off. If not, it checks whether the time interval has been reached. If it has not been reached, it continues timing and checks whether the motor has stopped. If the time interval has been reached, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and timing continues, repeating until the motor stops, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and the camera is powered off.After the system is powered on, it checks whether the left and right experimental boards are started and whether the camera is turned on, and also checks whether the water pump is started. If it is not started, the water pump is stopped; if it is started, it reads the preset water pump running time parameter and assigns it to the corresponding functional module; the water pump starts running; the timer starts counting and assigns a value to the corresponding functional module in real time; it checks whether the running time has reached the preset value. If it has, the water pump stops, the timer stops counting, and the data of the timer module assigned in real time is cleared to zero; if it has not reached the preset value, it continues counting until the running time has reached the preset value, at which point the water pump stops, the timer stops counting, and the data of the timer module assigned in real time is cleared to zero. The first servo motor, the second servo motor, the camera, and the water pump are all independently controlled and there is no interlocking relationship. They can be controlled individually or simultaneously.

[0010] Optionally, an indicator light is embedded in the center of the lower part of the servo motor module; sliding mechanism legs are welded to the four vertices of the lower part of the rectangular steel frame; and an anti-slip pad is attached to the bottom of each sliding mechanism leg.

[0011] Optionally, the equipment base system also includes a bottom cylinder support; the four bottom cylinder supports are respectively located at the four vertices below the bottom cylinder; the bottom of the bottom cylinder support is connected to a movable wheel via a movable wheel connector; a manual brake pad is connected to the movable wheel.

[0012] Optionally, the experimental auxiliary system further includes a track rod assembly; each experimental auxiliary system support frame has two sets of track rod assemblies arranged vertically welded to its inner side, and each set of track rods has a first groove on one side of the two track rods facing each other; pulleys are welded to both ends of the guide rods, and the pulleys are movably disposed in the first groove of the track rod assembly; the upper track rod assembly is movably connected to one guide rod, and the lower track rod assembly is movably connected to three guide rods; the water spray head is disposed on the three lower guide rods, and the camera is disposed on the upper guide rod.

[0013] Optionally, each guide rod has a second groove below it, and a fixing member is movably connected in the second groove. Each fixing member can move freely along the groove of its respective guide rod independently. The camera is connected to the fixing member located on the upper guide rod. Multiple water nozzles are respectively connected to the fixing member located on the right side of the lower guide rod. Multiple fixing members located on the left side of the lower guide rod are respectively connected to a hose reel. The water nozzle is connected to a diversion water drain through a water pipe, and the water pipe located between the diversion water drain and the water nozzle is wound around the hose reel. The output end of the water pump is connected to the input end of the diversion water drain through a main water pipe.

[0014] Optionally, a plurality of rings are movably fitted on the guide rod located below, the rings being used to restrain water pipes and wires arranged along the guide rod.

[0015] This invention also provides an experimental method for simulating the deformation process of strike-slip faults along with sedimentation, comprising the following steps:

[0016] The first step is to select the number of water spray heads based on the actual work area to be simulated, and manually adjust the opening of the selected water spray heads and the distribution position of the water spray heads.

[0017] The second step is to add water to the storage tank, and according to the location of the sedimentation point, reduce the model size to a scale of 1:105 to obtain the model size and lay the experimental materials.

[0018] The third step is to turn on the control system of the experimental device, set the control parameters of each module according to actual needs, and start the device to run; the modules include a first servo motor, a second servo motor, a camera, and a water pump;

The experimental plate, brush-equipped flap, and baffle of this invention are fixed together as a single unit, greatly reducing sand leakage during experiments. The bottom cylinder design provides a centralized collection structure for waste materials (sand, water, and other experimental materials) generated during the simulation, effectively preventing pollution of the laboratory environment and facilitating cleaning of the entire experimental equipment's mechanical structure.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide an experimental apparatus and method for simulating the depositional deformation process of strike-slip faults, so as to solve the problems existing in the prior art and enable different degrees and forms of strike-slip fault depositional simulation experiments as needed.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figure 1 , Figure 2 and Figure 3 This invention provides an experimental apparatus for simulating strike-slip fault depositional deformation processes, comprising a foundation system, an experimental auxiliary system, a strike-slip simulation system, and a control system. The foundation system supports the entire experimental apparatus and provides a mechanism for convenient collection of experimental waste. It includes: a base cylinder 22, a base cylinder support 23, a manual brake pad 24, a caster wheel connector 25, a water storage tank 8, and casters 32. The base cylinder 22 is 3.2m long, 3m wide, and 1m high, with a width of 10cm on each side. The interior of both sides is hollow, made of stainless steel, to prevent experimental materials from falling into the laboratory and causing inconvenience during the simulation experiment. A 5cm diameter hole is opened in the center of the base cylinder 22 for easy drainage during cleaning. A top view of the base cylinder 22 is shown below. Figure 3 As shown; the water storage tank 8 is a cubic water storage mechanism with a length of 1m, a width of 1m, and a height of 1m, formed by welding two steel plates with a side length of 1m to the lower left corner of the bottom tank 22 and the two sides of the bottom tank 22. It is used to hold the water required for simulating sedimentation; the four bottom tank legs 23 are 1m high and are located near the four vertices below the bottom tank 22, so that they are at a certain height from the ground, which is convenient for collecting waste when cleaning the bottom tank 22 and the sliding mechanism; the four moving wheel connectors 25 are welded to the bottom of the four bottom tank legs 23 to connect four moving wheels 32 with an outer diameter of 8cm, which is convenient for moving the experimental equipment; each moving wheel 32 is also connected to a set of manual brake pads 24 that match the moving wheel 32, which is used to brake the moving wheel 32, so that the entire experimental equipment is fixed in the current position after all the manual brake pads 24 are pressed.

[0033] The experimental auxiliary system provides auxiliary mechanisms for simulating strike-slip tectonics and deposition processes in the entire experimental equipment, such as a camera for recording process data and a simulated water source during deposition. It includes: pulley 1, a diversion drain 2, an experimental auxiliary system support frame 3, track rods 4, guide rods 5, rings 6, a winding hose reel 7, a water pump 9, a water pipe 10, a spray nozzle 11, a camera 13, and fixing components 16. Two stainless steel experimental auxiliary system support frames 3, each 2m high, 2.8m long, and 6cm wide, are welded to the bottom of the bottom cylinder 22 at the middle positions on both sides. Four sets of 2.7m long track rods 4 are welded to the inner sides of the experimental auxiliary system support frames 3 at both ends, and each track rod 4 has a groove. The grooves of each set of track rods 4 serve as the track for the pulley 1 to slide freely on the track rod 4. The width of the wheel 1 fits perfectly with the slot. The spacing between the two rail rods in each group 4 is such that the pulley can be locked in place and moved within its groove. The four groups of rail rods 4 are arranged in pairs as a large group, with the two large groups spaced vertically at a distance of 30cm. The two small groups of rail rods 4 in each large group are parallel. The two ends of the four 3.1m long guide rods 5 are welded to the pulley 1, which ensures that the guide rods 5 can slide freely along the groove on the rail rods 4 through the pulley 1. The four guide rods 5 are divided into two groups, with the vertical distance between the two groups of guide rods 5 being 30cm. The vertical distance between the lower group and the lower part of the experimental auxiliary system support frame 3 is 1m.A 5m section consists of three guide rods 5 connected to a large set of track rods 4 below, and one guide rod 5 connected to a large set of track rods 4 above. Each guide rod 5 can slide freely on the track rod 4 via pulleys 1. Each guide rod 5 also has a groove below it to allow the free movement of fixing members 16. Nineteen fixing members 16 are connected to the guide rods 5 via the grooves below them, and each fixing member 16 can move freely along the grooves below the guide rods 5. One fixing member 16 is connected to the upper guide rod 5, and the other eighteen fixing members 16 are connected to the lower guide rods 5 in groups of six. A camera 13 (Canon EOS-6D-Mark) is connected to the lower part of the upper fixing member 16 and can move freely along the grooves on the guide rods 5 via the fixing member 16. Nine adjustable spray heads 11 are connected to the lower right section of the guide rod 5 in groups of three. The lower ends of the three fixing parts 16 are connected, and each spray head 11 can move freely along the groove on the guide rod 5 relatively independently through the fixing parts 16; nine 20cm diameter outer disc spiral wound hose reels 7 are connected in groups of three to the lower ends of the three fixing parts 16 located on the lower left, and each spiral wound hose reel 7 can move freely along the groove on the guide rod 5 relatively independently through the fixing parts 16. The spiral wound hose reels 7 are used to wind up the excess length of the water pipe 10; one end of the plastic water pipe 10 is connected to the spray head 11, and the other end is connected to the output end of the diverter 2, and part of the water pipe is wound on the spiral wound hose reel 7. The diverter is a customized thickened type with one inlet and nine outlets; the output end of the water pump 9 is connected to the input end of the diverter 2 through a large water pipe 10. The water pump is model EB-301; several 5cm diameter ring buckles 6 are located at different positions on each guide rod 5 and can move freely along the guide rod relatively independently to constrain the water pipe 10 and the wire 28 along the guide rod 5. The design of the guide rod 5 and track rod 4 in this system ensures that the water nozzle 11 and camera 13 can move to any position on their respective horizontal planes, thus facilitating the fulfillment of different experimental requirements.

[0034] The slip-slip simulation system is used to simulate slip-slip structural motion and is the core lower-level mechanism of the entire experimental equipment. It consists of two parts, left and right. Each part includes a rectangular steel frame 12, a toothless screw 14, a lead screw 15, a brush-equipped flip plate 17, an anti-slip pad 18, slip-slip mechanism legs 19, a baffle 20, an experimental plate 21, an indicator light 29, a servo motor module 30, and a ring buckle 31. Each experimental plate 21, 1.5m long, 1m wide, and 5mm thick, has a baffle 20, 1.5m long, 25cm high, and 5mm thick, vertically welded to the top of each of its three edges. The baffle 20 is not welded to the joint between two experimental plates 21; instead, a brush-equipped flip plate is welded to the bottom. Plate 17 is used to prevent sand leakage from the joint of the two experimental plates 21 during the simulated slippage process. The lower part of each experimental plate 21 is connected to two 1.45m long threaded rods 14 via annular clips 31. The inner diameter of the annular clips 31 is sufficient to fix the threaded rods 14 relatively, meaning that the annular clips 31 and the threaded rods 14 move along the threaded rods 14 with the experimental plate 21 without significant relative displacement. The two ends of the threaded rods 14 are welded to the inside of a rectangular steel frame 12, which is 1.5m long, 80cm wide, and 2.5cm thick. The bonding lines of the two experimental boards 21 are parallel to each other; the lower center of each experimental board 21 is connected to a 1.45m long lead screw 15 via a servo motor module 30 fixedly connected to it. The lead screw 15 is located between two toothless screws 14, passes through the servo motor module 30, and its two ends are welded to the inner side of the rectangular steel frame 12. The servo motor model is D08LD40-12A-30S, and the driver model is BLD-120A. This motor has good acceleration performance and can quickly reach the specified speed, which is quite suitable for the device of this invention; thus, by controlling the servo motor... The speed and direction of the servo motor control the movement speed and direction of the experimental board 21. An indicator light 29 is embedded in the center of the lower part of the servo motor module 30; the indicator light indicates the working status and mode of the servo motor by whether it is lit or not, and the color of the lit light. Eight 80cm high sliding mechanism legs 19 are welded to the four vertices of the lower part of each rectangular steel frame 12 to support the entire sliding simulation mechanism. Each sliding mechanism leg 19 has an anti-slip pad 18 attached to its underside to prevent slippage of the sliding simulation system during servo motor operation. A schematic diagram of the bottom structure of the sliding system is shown below. Figure 2 As shown, in the initial state, the experimental plate 21 is completely overlapped with the rectangular steel frame 12. The unidirectional displacement range of the experimental plate 21 is 0 to 75 cm. Therefore, the experimental plate can never exceed the boundary of the bottom cylinder 22, which meets the structural requirements and is fully capable of meeting the needs of actual sand box physical simulation experiments.

[0035] The control system is the central hub for the entire experimental equipment to conduct simulation experiments, including a host computer 26, a measurement and control module 27, and wires 28. The host computer 26 provides a host computer operation interface, displays the current working status of the equipment, and provides an input window for operation commands. The application software for the host operation interface is RSview32. The measurement and control module 27 includes a PLC (Programmable Logic Controller), an A / D (Analog-to-Digital) converter, and a D / A (Digital-to-Analog) converter. The PLC model is Rockwell Micro850, and the converter model is DAC6573IPW. Camera 13, water pump 9, and servo motor module 30 are connected to measurement and control module 27 via wire 28. Measurement and control module 27 is connected to host computer 26. The programmable logic controller (PLC) has a pre-installed control program. The operator inputs control commands through the host computer 26's interface. The digital signal output by the host computer is transmitted to measurement and control module 27. Measurement and control module 27 converts the digital signal from the host computer to an analog signal via a D / A converter and transmits it to each drive module. Each drive module operates according to the input command's required state. Simultaneously, measurement and control module 27 receives the status signals from each drive module, converts the analog drive status signal to a digital signal via an A / D converter, and transmits it to host computer 26 for real-time status display on the interface. The PLC program in the measurement and control module follows the instructions... Figure 4 The control flow concept shown is edited.

[0036] The PLC built-in program follows Figure 4 The written control program flow and the upper-level interface design of this invention can achieve the following functions:

[0037] Function 1: After the system is powered on, the motor automatically determines whether the left and right experimental boards are started. Since the control methods of the left and right experimental boards are the same and they are independent without interlocking, they can be controlled individually or simultaneously. This description uses the left experimental board as an example. When the left experimental board is determined to be in a non-starting state, the first servo motor remains stationary. If the left experimental board is determined to be in a starting state, the axis motion initialization configuration begins, namely, the first servo motor axis motion module clears errors and marks the coordinate zero point; the preset left experimental board motion time and motion speed parameters are read and assigned to the corresponding functional modules; the target distance is calculated and assigned to the next functional module, target distance = speed * time; the calculated linear distance is converted into wheelbase; the wheelbase is assigned to the corresponding functional module to determine the relationship between the current distance to be traveled and zero: ①. Determine if the current distance to be traveled is greater than zero. If yes, the servo motor rotates forward; ②. Determine if the current distance to be traveled is greater than zero. If no, then determine if the current distance to be traveled is less than zero. If yes, the servo motor rotates in reverse; ③. Determine if the current distance to be traveled is greater than zero. If no, then determine if the current distance to be traveled is less than zero. If no, the servo motor remains stationary. During the operation of the first servo motor, it continuously determines whether the target point has been reached. If it has, the motor stops immediately; if it has not, the motor continues its original operation. If no motion time parameter is preset, the system defaults to an infinite time, requiring the operator to issue a stop command or cut off the power through the host computer interface to stop the motor.

[0038] Function 2: After the system is powered on, it determines whether the left and right experimental boards are started, and also whether the camera is turned on. If the camera is not turned on, it will not receive power. If the camera is turned on, it reads the preset photo interval parameter and assigns it to the corresponding functional module. The camera shutter is triggered once, and a photo is taken. Then the timing module starts working and assigns the value to the corresponding functional module in real time. It determines whether the servo motor has stopped. If so, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and the camera is powered off. If not, it then determines whether the time interval has been reached. If not, it continues timing and determines whether the motor has stopped. If the time interval has been reached, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and timing continues, repeating this cycle until the motor stops, the timer stops, the real-time assigned timing module data is cleared, the camera shutter is triggered once, a photo is taken, and the camera is powered off.

[0039] Function 3: After the system is powered on, while determining whether the left and right experimental boards are started and whether the camera is turned on, it also determines whether the water pump is started. If it is not started, the water pump is in a stopped state; if it is started, the preset water pump running time parameter is read and assigned to the corresponding functional module; the water pump starts running; the timer starts counting and is assigned to the corresponding functional module in real time; it is determined whether the running time has reached the preset value. If it has, the water pump stops, the timer stops counting, and the data of the timer module assigned in real time is cleared to zero; if it has not reached the preset value, the timer continues to count until the running time has reached the preset value, then the water pump stops, the timer stops counting, and the data of the timer module assigned in real time is cleared to zero.

[0040] Function 4: Because the relevant instructions and modules in the program are associated with the corresponding labels in the upper-level interface, the upper-level operation interface can not only input control instructions, but also monitor in real time the movement speed, remaining movement time, current movement displacement and movement direction of the current running segment.

[0041] The first servo motor, second servo motor, camera, and water pump are all independently controlled and not interlocked. They can be controlled individually or simultaneously. When using this equipment, it should be noted that the time values ​​mentioned in this system must be greater than zero when input. When the input speed is positive, the experimental board moves in the direction of the arrow, and the indicator lights on the upper-level operation interface and the corresponding servo motor module are both green. When the input speed is negative, the experimental board moves in the opposite direction of the arrow, and the indicator lights on the upper-level operation interface and the corresponding servo motor module are both red. If the running time of the water pump and servo motor is not specified, the system defaults to infinity, requiring the operator to manually stop their operation.
