Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of artificial fracture, specifically to a simulation device of artificial fracture. BACKGROUND

[0002] At present, volume fracturing technology has obtained wide popularization and application, but its core is to maximize the net pressure of the fracture. Due to the relatively small width of the fracture, the friction of the fracture is large, so that after the pressure in the wellbore is transmitted to the end of the fracture, it will be reduced to a certain extent. The current pressure monitoring means can only monitor in the wellbore, and the pressure at different positions of the fracture is different due to the different friction of the fracture. Therefore, it is difficult to accurately determine the net pressure at different positions in the fracture, and the complexity of the fracture is difficult to accurately predict and control.

[0003] The conventional fracture simulation device cannot adjust and control the simulated fracture when testing and simulating different fractures, thereby affecting the data of the fracture simulation test experiment. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a simulation device for artificial fracture, which solves the problems raised in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a simulation device for artificial fracture, comprising a fixed seat, the top of two fixed mounting seats is fixedly connected with a gear strip, the outer side of the gear strip is sleeved with an adjusting mechanism, the inner side of the adjusting mechanism is fixedly connected with an adjusting frame, the inner side of the adjusting frame is provided with a pushing mechanism, one side of the pushing mechanism is provided with a simulation mechanism.

[0006] Preferably, the adjusting mechanism comprises a limiting frame in sliding connection with the outer side of the gear strip, a gear is movably connected to the inner side of the limiting frame, a handle is installed at the top of the gear, a slide rail is fixedly connected to the top of the adjusting frame, a movable sliding seat is slidably connected to the top of the slide rail, an electric telescopic rod is fixedly connected to one side of the top of the movable sliding seat, and a pressing block is fixedly connected to the telescopic end of the electric telescopic rod.

[0007] Preferably, the pushing mechanism comprises a small electric telescopic rod fixedly connected to the inner side of the adjusting frame, a pushing frame is fixedly connected to the telescopic end of the small electric telescopic rod, a third electric telescopic rod is fixedly connected to one side of the pushing frame, a movable adjusting frame is fixedly connected to one side of the third electric telescopic rod, a connecting frame is fixedly connected to one side of the movable adjusting frame, and the top of the connecting frame is fixedly connected to one side of the movable sliding seat.

[0008] Preferably, the simulation mechanism includes a fixed mounting base, with a plurality of mounting brackets fixedly connected to the top of the fixed mounting base. One end of each mounting bracket is movably connected to a hinge, and one side of each hinge is fixedly connected to a simulated gap wall.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention provides a device for simulating artificial cracks:

[0011] 1. When the simulated gap wall is opened and closed, the throttle is used to drive the gear to rotate, so that the gear can mesh with the gear rack while rotating, thereby facilitating the mutual movement and adjustment of the adjustment frame. The horizontal adjustment and control of the simulated gap wall is achieved by sliding the movable slide on the slide rail to the simulated position. After that, the extension and retraction of the electric telescopic rod drives the pressing block to press and fix the side of the adjustment frame to prevent the movable slide from sliding.

[0012] 2. The small electric telescopic rod fixedly connected to one side of the adjustment frame allows for easy movement of the adjustment frame. After the frame is in a designated position, the third electric telescopic rod extends and retracts to move the adjustment frame closer to or further away from each other, allowing for longitudinal adjustment of the simulated gap wall. This facilitates simulation testing. When simulating artificial gaps, the hinges on the mounting bracket on the fixed base can be used to adjust the simulated gap wall, and the two simulated gap walls can be adjusted together for simulation.
