%X This data set collates and collects the experimental data set of wellbore annulus pressure during the implementation of the project (June 2018). The measurement elements include annulus, pressure, radial strain, circumferential strain and other field data. The indoor experimental data collection time of the project began on June 1, 2018 and ended on June 31, 2018. A total of 276 groups of indoor experiments were carried out, and the experimental data set was fully open and shared. Through the simulated pressurization of different annular cavities, because the string cavity is in a closed state, the annular cavity will affect the volume change of the inner cavity of the string under the action of pressure, and the volume change will further affect the stress and strain of the string. Therefore, the experimental design is mainly to explore the strain law of different annulus string under different pressurization conditions
