DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a wellbore bearing capacity test device.
[0032] like Figure 1 As shown, the wellbore bearing capacity test equipment includes a power device, a pressure device and a detection device. The power device is used to provide power to the pressure device, the pressure device is used to apply pressure to the wellbore, and the detection device is used to detect the strain generated by the wellbore after being subjected to pressure.
[0033] The power device, as the power source of the pressure device, ensures the stability and accuracy of the pressure process; the pressure device can apply a predetermined pressure to the wellbore to simulate the stress state under actual working conditions; the detection device can accurately capture the strain data of the wellbore after being subjected to pressure and comprehensively evaluate the bearing capacity of the wellbore. This solution effectively solves the problem of the lack of special equipment in the existing technology and improves the efficiency and accuracy of the experiment.
[0034] like Figure 1 As shown, the power device includes a hydraulic pump, the pressure device includes a hydraulic jack 1, the hydraulic pump is connected to the hydraulic jack 1 through a hydraulic pipe, a pressure gauge is provided on the hydraulic pipe, a load 2 is provided on the top of the hydraulic jack 1, and a pressure head 3 is detachably connected to the bottom of the hydraulic jack 1.
[0035] Compared with other types of mechanical systems, hydraulic systems usually have higher energy conversion efficiency, reduce energy consumption, and reduce noise and heat generation. The coordinated work of the hydraulic pump and the hydraulic jack 1 provides a stable and controllable power source for the pressure device, ensuring that the pressure applied to the wellbore is uniform and reliable. At the same time, the hydraulic system can respond quickly, achieve rapid loading and unloading, and greatly improve the operation efficiency.
[0036] The pressure gauge installed in the hydraulic pipeline can monitor and display the pressure value in real time, so that the hydraulic jack 1 can be fine-tuned, allowing the operator to perform fine control to meet the precise pressure requirements under different experimental conditions. The load 2 can be a mounting frame filled with heavy objects. The top load 2 design of the hydraulic jack 1 ensures that the pressure is applied smoothly during the detection process. The detachable connection head 3 design at the bottom allows the equipment to flexibly replace the adapter parts according to the different shapes or sizes of the well, thereby improving the adaptability and efficiency of the experiment. The detachable connection method can be a flange connection or a threaded connection.
[0037] like Figure 1 As shown, the detection device includes a pressure sensor 5 and a displacement laser rangefinder 4. The pressure sensor 5 is arranged at the bottom edge of the pressure head 3 to detect the pressure between the pressure head 3 and the wellbore, and the displacement laser rangefinder 4 is arranged at the top of the pressure head 3 to detect the distance between the pressure head 3 and the load 2.
[0038] The pressure sensor 5 is arranged at the bottom edge of the pressure head 3, and can accurately detect whether the pressure head 3 is in full contact with the surface of the wellbore, ensuring the effective conduction of pressure during the experiment and avoiding measurement errors caused by poor contact. In addition, it can also detect the pressure of the pressure head 3 and the wellbore in different directions, and then evaluate the strain of the wellbore. The displacement laser rangefinder 4 located at the top of the pressure head 3 is used to accurately measure the distance change between the pressure head 3 and the load 2, so as to accurately obtain the vertical displacement data of the wellbore under pressure, and provide key data support for evaluating the bearing capacity of the wellbore.
[0039] In actual use, the hydraulic jack 1 gradually drives the pressure head 3 to approach the wellbore until the bottom of the pressure head 3 contacts the wellbore. At this time, the pressure sensor 5 starts to read, and the displacement laser rangefinder 4 and the pressure gauge start to record data at the same time. The operator captures the changes in various physical quantities of the wellbore after being pressurized, and then comprehensively evaluates the bearing capacity performance of the wellbore.

[0041] The configuration of the arm-type strain gauge 6 enables the device to accurately measure the horizontal displacement changes of the inner wall of the wellbore when it is under pressure. Specifically, the multiple telescopic measuring arms equipped with the arm-type strain gauge 6 can capture the subtle changes on the wellbore surface in all directions, thereby providing more comprehensive and accurate strain data. This type of design not only improves the reliability of the experimental results, but also enhances the adaptability of the device to complex wellbore structures.
[0042] In some other embodiments, the detection device may further include a horizontal mounting seat and a plurality of horizontal laser rangefinders. The horizontal mounting seat is located at the bottom of the pressure head 3 and is coaxially arranged with the hydraulic jack 1. The horizontal laser rangefinders are arranged at equal intervals around the horizontal mounting seat. The measuring direction of the horizontal laser rangefinder is arranged radially along the horizontal mounting seat and toward the side away from the horizontal mounting seat.
[0043] The design of a horizontal mounting seat and multiple horizontal laser rangefinders enables the equipment to measure the horizontal displacement changes of the inner wall of the wellbore during the compression process. Specifically, the coaxial arrangement of the horizontal mounting seat and the hydraulic jack 1 ensures the stability of the structure, while the horizontal laser rangefinders arranged at equal intervals achieve effective monitoring of the horizontal deformation of multiple points on the wellbore surface, thereby improving the accuracy and reliability of the experimental data. This design is particularly suitable for bearing capacity testing of wellbores with complex shapes and enhances the adaptability of the equipment.
[0044] like Figure 1 As shown, the detection device also includes a well depth laser rangefinder 7, which is located below the pressure head 3 and coaxially arranged with the hydraulic jack 1. The measuring direction of the well depth laser rangefinder 7 is arranged along the axial direction of the hydraulic jack 1 and toward the side away from the hydraulic jack 1.
[0045] The configuration of the well depth laser rangefinder 7 enables the equipment to detect the well depth. Specifically, the coaxial configuration of the well depth laser rangefinder 7 and the hydraulic jack 1 realizes the effective monitoring of the well depth, ensures the stability and accuracy of the measurement, effectively reduces the measurement error, and improves the accuracy of the measurement results. At the same time, it simplifies the operation process of well depth detection and significantly improves work efficiency.
