Problems solved by technology
After the internal blowout prevention tool is manufactured, it must be tested. Generally, the torque curve and pressure curve need to be drawn according to the test results, and the sealing performance of the male buckle, the female buckle and the barrel needs to be tested. The existing test equipment structure is relatively Complicated, not conducive to efficient completion of testing work

The invention relates to an internal blowout prevention tool testing device. A pressing cylinder is installed at the upper end of a support, a piston rod of the pressing cylinder is arranged to face downwards, a locating block used for locating an internal blowout prevention tool to be tested is arranged on a support bottom plate below the piston rod, and a tool used for connecting the lower end of the piston rod with the internal blowout prevention tool to be tested in a sealed mode is installed at the lower end of the piston rod; the pressing cylinder is driven by a hydraulic pressure station, a water channel is made in the piston rod of the pressing cylinder from top to bottom, the upper end of the water channel is communicated with high-pressure water, and the lower end of the water channel is communicated with the interior of the internal blowout prevention tool to be tested through the other water channel made through tool alignment. According to the internal blowout prevention tool testing device, all parts are integrated together, use is very convenient, transportation is convenient, testing of the internal blowout prevention tool to be tested before market selling can be completed, work of quality control personnel is greatly convenient, and the quality of the product is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of improving detection equipment for internal blowout prevention tools, in particular to a testing device for internal blowout prevention tools. Background technique [0002] During the drilling process, when the formation pressure exceeds the hydrostatic column pressure of the drilling fluid, in order to prevent the formation pressure from pushing the drilling fluid drill string water hole upwards and protect the hose from damage due to high pressure, it is necessary to use the internal blowout prevention tool. Its structure is: including a cylinder and a cock, a male buckle is set at one end of the cylinder, and a female buckle is set at the other end of the cylinder. Both the male buckle and the female buckle are used to connect other parts, and a cock is set in the cylinder. The torque wrench arranged on the outer edge of the cylinder is linked, and a torque sensor is arranged on the torque wrench. When...
