The invention discloses a simulation experiment well. The simulation experiment well comprises a wellhead apparatus, a test inner shaft and a test outer shaft, the test inner shaft and the test outershaft are both in vertical states, the test inner shaft is arranged in the test outer shaft in a sleeved manner, the wellhead apparatus is arranged above the test outer shaft, the wellhead apparatus is connected with the upper end of the test inner shaft, the lower end of the test inner shaft is connected with the lower end of the test outer shaft through an anti-rotating mechanism, and the anti-rotating mechanism can prevent the rotation of the test inner shaft relative to the test outer shaft. The simulation experiment well can be arranged underground so that problems of long construction period, large investment, and inconvenient maintenance of the conventional test well are solved.
