The application provides a four-cavity pressure simulation evaluation method with a capillary design kettle body, a platform and a wellbore. The kettle body is internally and externally provided with a tool pipe column, a packer rubber tube and a test casing, a capillary injection port is arranged on the upper end of the kettle body, and the capillary passes through the space between the test casing and the kettle body and is connected with the lower end of the test casing. The platform comprises the kettle body. The method is realized based on the kettle body. When the high-temperature and high-pressure downhole tool detection and evaluation is carried out, the strength of the test casing tooling is not additionally increased due to the limited structure, and the overall cost of the test is saved. After the four cavities are independently realized, the leakage of each cavity can be judged in the test process, and the test working condition of the downhole tool sample can be more accurately judged. The system pump injection pressurization efficiency is improved, and the detection precision and speed are improved. The internal cooling is realized at the same time as the pressure maintenance in the casing and outside the casing, and the interference on the test working condition during the cooling period is reduced.
