Description

Technical Field

[0001] The present application relates to the technical field of pressure testing, and in particular to a pressure testing device and a testing method thereof. Background Art

[0002] The function of the pressurizing device is to test the pressure of the rotary drilling rig and check whether the rotary drilling rig has the ability to apply pressure. At present, the pressure test is mainly done by directly acting on the pressure sensor placed on the ground through the pressurizing device (pressurizing cylinder or pressurizing winch), and the pressure value calculated by the pressure sensor is used to judge the ability of the rotary drilling rig to apply pressure.

[0003] At present, when the pressurization device is tested, the pressure gauge will be installed; when the pressure test is carried out with a rod, the pressure gauge is placed directly on the floor. During the pressurization process, the pressure gauge often slides on the ground after being pressurized, which not only causes damage to the pressure gauge, but also endangers personal safety in dangerous situations. Moreover, when the pressurization method with a rod is adopted, it is limited by the number of drill rods in the commissioning field and cannot meet multiple rotary drilling rig tests at the same time, and the test waiting time is long. In addition, when the power head pressure plate is used for pressurization testing, a pressure platform simulation is required, and the pressure platform is simulated by stacking heavy blocks. The heavy blocks are composed of multiple parts, and collapse accidents are prone to occur during use, which may cause personal safety. Finally, the preparation process for pressurization with a rod (the process of connecting and hanging the rod) is cumbersome, and the stacking process of the pressure platform is complicated, which consumes a lot of manpower and material resources.
