This dataset compiles and collects experimental data on wellbore annulus pressure during the project implementation period (June 2018), with measurement elements including annulus, pressure, radial strain, circumferential strain, and other field data. The collection of indoor experimental data for this project began on June 1, 2018 and ended on June 31, 2018. A total of 276 sets of indoor experiments were conducted, and the experimental dataset was fully open for sharing. By simulating pressurization of different annular cavities, due to the closed state of the column cavity, the annular cavity will affect the volume change of the column cavity under pressure, and the volume change will further affect the stress and strain of the column. Therefore, the experimental design mainly aims to explore the strain patterns of different annular layer columns under different pressure conditions.
Experimental experiments, independently generated.
