Deposition rate has a significant impact on oil formation; rapid deposition allows organic matter to be quickly buried, preventing oxidation and promoting oil formation. The higher the deposition rate, the more favorable it is for oil and gas generation.

[0003] In existing technologies, geological sedimentary studies of deltas require the simulation of geological sedimentation. However, existing simulation devices do not easily allow the addition of new sand and soil, making the simulation process quite complex. Utility Model Content

The top of the water tank is connected to an external water source via a hose and a water pump.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a geological sedimentation simulation device for petroleum geological research includes a simulation box 1. The simulation box 1 has a hollow structure and an open top. A guide slope 2 is fixedly installed at the bottom of the inner wall of the simulation box 1. The guide slope 2 has a right-angled triangular structure, and its vertical side is in contact with one end of the inner wall of the simulation box 1. The top of the guide slope 2 has a sloping side structure, and a downwardly recessed simulated river channel 3 is formed on the sloping side of the guide slope 2. A rainwater simulation mechanism is installed at the top of the simulation box 1 directly above the simulated river channel 3. A feeding mechanism is installed at one end of the simulation box 1 to feed soil and gravel into the simulated river channel 3. The bottom edge of the guide slope 2 has a buffer area with one end of the inner wall of the simulation box 1.

[0021] In this embodiment: First, by starting the feeding mechanism, the feeding mechanism inputs soil or gravel into the simulated river channel 3, and by using a water pump, external water is input into the rainwater simulation mechanism. The water is discharged from the output end of the rainwater simulation mechanism, simulating rainwater dripping down and impacting the soil and gravel. The impacted soil and gravel slide along the simulated river channel 3 and flow to the buffer zone, forming a simulated deltaic depositional area.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The rainwater simulation mechanism includes a water tank 4 mounted on top of the simulation box 1 via a fixed frame. The output end of the water tank 4 is integrally formed with a water nozzle 5. The inner wall of the water nozzle 5 is connected to the inner wall of the water tank 4, and the bottom end of the water nozzle 5 is open. The top of the water tank 4 is connected to an external water source via a hose and a water pump. A baffle 11 is fixedly installed on the inner wall of the straight groove of the water nozzle 5. Multiple water holes 12 are opened inside the baffle 11.

[0023] In this embodiment: by starting the water pump, the water pump runs through the pipeline to the water tank 4, the water enters the water nozzle 5 through the water tank 4 and flows out from the water nozzle 5. After the water flows through the baffle 11, it drips down from the water hole 12 to form a raindrop effect.

[0024] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4The feeding mechanism includes a connecting cylinder 6 installed on one end of the simulation box 1 via a fixed bracket. The output end of the connecting cylinder 6 is integrally formed with a discharge nozzle 7. The inner cavity of the discharge nozzle 7 is connected to the inner cavity of the connecting cylinder 6, and the end of the discharge nozzle 7 away from the connecting cylinder 6 is open. The feeding mechanism also includes a rotary motor 9 installed on the end of the connecting cylinder 6 away from the discharge nozzle 7. The output shaft of the rotary motor 9 passes through the inner cavity of the connecting cylinder 6. A spiral conveying rod 10 is fixedly installed on one end of the output shaft of the rotary motor 9. A funnel 8 is integrally formed on the upper outer periphery of the connecting cylinder 6, and the inner cavity of the funnel 8 is connected to the inner cavity of the connecting cylinder 6.

[0025] In this embodiment: by starting the rotary motor 9, the output shaft of the rotary motor 9 drives the screw conveyor 10 to rotate. At this time, sand or soil is added into the funnel 8. The added sand or soil enters the connecting cylinder 6 through the funnel 8. The rotating screw conveyor 10 then enters the connecting cylinder 6 and is conveyed to the discharge nozzle 7. The sand or soil enters the top of the simulated river channel 3 through the discharge nozzle 7.

[0026] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 An inlet hole 13 is provided at the position where the vertical plate of the simulation box 1 meets the opening of the discharge nozzle 7. A guide plate 14 protruding outward is integrally formed above the end of the inlet hole 13 near the inner wall of the simulation box 1. The lower part of the guide plate 14 is inclined, and the inclined surface of the guide plate 14 is parallel to the extension direction of the simulated river channel 3.

[0027] In this embodiment: when sand and soil enter the simulated river channel 3 through the inlet hole 13, they enter the simulated river channel 3 under the guidance of the inclined surface at the bottom of the guide plate 14, so as to avoid the soil and sand from being ejected when they move out of the inlet hole 13.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
