Pressure-bearing testing device of multi-position pressure-bearing crack temporary plugging agents

The utility model relates to the technical field of pressure-bearing testing devices, and provides a pressure-bearing testing device of multi-position pressure-bearing crack temporary plugging agents. The pressure-bearing testing device comprises a pressure-bearing kettle body, an upper cover body and a lower plug; the upper end of the pressure-bearing kettle body is fixedly provided with the upper cover body, the lower end of the pressure-bearing kettle body is fixedly provided with the lower plug, a pressure-bearing cavity is formed among the upper cover body, the pressure-bearing kettle body and the lower plug, the upper cover body is provided with an installation hole communicated with the pressure-bearing cavity, and the lower plug is provided with at least one pressure-bearing crack communicated with the pressure-bearing cavity. The pressure-bearing testing device is reasonable and compact in structure and convenient to use, the pressure-bearing kettle body, the upper cover body, the lower plug and a pressure inlet valve are matched for use, pressure-bearing ability of the multi-position pressure-bearing crack temporary plugging agents in the stratum can be simulated really, and the pressure-bearing testing device has the advantages of being good in sealing performance, safe and reliable. Testing accuracy of the pressure-bearing ability of the temporary plugging agents is improved, and the theoretical foundation is provided for stress cracking construction.
