Description

Technical Field

[0001] This utility model relates to the field of reservoir experimental numerical simulation technology, and in particular to an easy-to-operate reservoir experimental numerical simulation system. Background Technology

[0002] An oil reservoir refers to a basic accumulation of oil within a single trap under the same pressure system. If only petroleum is accumulated in a trap, it is called an oil reservoir; if only natural gas is accumulated, it is called a gas reservoir. When an oil reservoir contains several oil-bearing sand layers, it is called a multi-layered oil reservoir. During the development of oil reservoirs, simulation experiments are required, generally using experimental numerical simulation equipment.

[0003] The existing patented fine reservoir experimental numerical simulation device (publication number: CN214007141U) facilitates the replacement of rock and soil layers during use, solving the problem that inconvenient replacement affects the diversity and accuracy of simulation values. However, the replacement of rock and soil layers requires manual adjustment of the height of the first plate, which is time-consuming, labor-intensive, and difficult to operate. Furthermore, the raising and lowering of the first plate cannot be automatically controlled. Therefore, this utility model proposes an easy-to-operate reservoir experimental numerical simulation system. Utility Model Content

[0012] This invention provides an easy-to-operate numerical simulation system for reservoir experiments. Compared with existing technologies, it has the following advantages:

[0013] This design presents an easy-to-operate numerical simulation system for reservoir experiments. By installing a lifting assembly between the tank and the support plate, when the thickness of the soil and rock layers needs to be changed, the user controls the output ends of two sets of electric telescopic rods via the control panel to raise the pressure sensor and the support plate, thus allowing for the thickness change of the soil and rock layers. After the change is completed, the output ends of the electric telescopic rods are controlled to lower the pressure sensor and the support plate. When the support plate contacts the U-shaped plate, the pressure sensor detects a pressure feedback value, which is then fed back to the control panel, stopping the output ends of the electric telescopic rods. This allows for automatic control of the lifting and lowering of the support plate, eliminating the need for manual adjustment, saving time and effort, and improving simulation efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution for an easy-to-operate reservoir experimental numerical simulation system: an easy-to-operate reservoir experimental numerical simulation system includes a box 1, a control panel 2, a liquid collection tank 3, a pump body 4, a liquid inlet pipe 5, a shell 6 and a connecting pipe 8 on the outside of the box 1, an oil inlet pipe 7 and an electric push rod 9 on the outside of the shell 6, a circular plate 10 connected to the output end of the electric push rod 9, a U-shaped plate 11 and a support plate 12 inside the box 1, a lifting assembly 13 between the support plate 12 and the box 1, a limit frame 14 at the upper end of the support plate 12, a soil layer 15 inside the limit frame 14, and a rock layer at the bottom of the soil layer 15;

[0022] The lifting assembly 13 includes an auxiliary plate 131. The upper end of the auxiliary plate 131 is provided with a moving hole 132 and a guide hole 136. An electric telescopic rod 133 is provided at the upper end of the auxiliary plate 131. A pressure sensor 134 is connected to the output end of the electric telescopic rod 133. A guide rod 135 is provided inside the guide hole 136. The end of the guide rod 135 is connected to the guide hole 136.

[0023] like Figure 1-4 As shown, the housing 1 and control panel 2 are connected by bolts. The control panel 2 has control buttons and a display screen on its outside and a control circuit board and battery inside. The housing 1 and collection tank 3 are connected by bolts. The collection tank 3 and the output end of the pump body 4 are connected by a pipe. The input end of the pump body 4 is connected to the housing 1. The housing 6 and the housing 1 are connected by a connecting pipe 8. The housing 6 and the oil inlet pipe 7 are connected. The output end of the electric push rod 9 is fixedly connected to the circular plate 10. The circular plate 10 is adapted to the inside of the housing 6. The U-shaped plate 11 is fixedly connected to the housing 1. The housing 1 and the support plate 12 are connected by a lifting assembly 13. The limiting frame 14 is fixedly connected to the support plate 12. The soil layer 15 and the rock layer are laid inside the limiting frame 14, which facilitates the introduction of oil and water into the inside of the housing 1. The soil layer 15 and the rock layer are simulated.

[0024] like Figure 1-4As shown, there are two sets of auxiliary plates 131, symmetrically distributed. Moving holes 132 and guide holes 136 both penetrate the middle of the auxiliary plates 131. The number of guide holes 136 is twice the number of auxiliary plates 131. The electric telescopic rod 133 is connected to the auxiliary plates 131 by bolts. The electric telescopic rod 133 is electrically connected to the control panel 2. The output end of the electric telescopic rod 133 is adapted to the moving hole 132. The output end of the electric telescopic rod 133 is fixedly connected to the detection end of the pressure sensor 134. The pressure sensor 134 is electrically connected to the control panel 2. The pressure sensor 134 is connected to the support plate 12 by bolts. The guide rod 135 is fixedly connected to the support plate 12. The guide rod 135 is adapted to the guide hole 136. The guide rod 135 is fixedly connected to the limit block 137. This facilitates the lifting and lowering of the support plate 12, making it convenient to change the thickness of the soil layer 15 and rock layer inside the limit frame 14.

[0025] The working principle of this utility model is as follows: During the use of the simulation system, the lifting component 13 drives the support plate 12 to rise, and the soil layer 15 and rock layer are laid inside the limiting frame 14. Then, the support plate 12 is driven to fall and contact the U-shaped plate 11. Water is injected into the inside of the box 1 through the liquid inlet pipe 5. Then, the output end of the electric push rod 9 drives the circular plate 10 to fall, so that the oil inside the shell 6 is pressed into the inside of the box 1 through the connecting pipe 8. Then, the pump body 4 pumps the oil and water inside the box 1 into the liquid collection tank 3. The oil and water are discharged out in sequence through the external high-low difference pipe, thereby simulating the oil reservoir development situation and judging the condition of the soil layer 15 and rock layer.

[0026] It should be noted that, through the setting of the lifting component 13, when the soil layer 15 and the rock layer need to be changed to different thicknesses, the user controls the output end of the electric telescopic rod 133 through the control panel 2 to drive the pressure sensor 134 and the support plate 12 to rise, and at the same time drive the guide rod 135 to rise along the inside of the guide hole 136, thereby changing the thickness of the soil layer 15 and the rock layer inside the limit frame 14. When the soil layer 15 and the rock layer need to be simulated for testing, the output end of the electric telescopic rod 133 through the control panel 2 drives the pressure sensor 134 and the support plate 12 to fall. When the support plate 12 contacts the U-shaped plate 11, the pressure sensor 134 detects the pressure feedback value, which is then fed back to the control panel 2, controlling the output end of the electric telescopic rod 133 to stop running. Thus, the lifting and lowering of the support plate 12 can be automatically controlled without manual adjustment, saving time and effort, making it easy to operate, and improving its simulation efficiency.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
