2026-09-29 Data set for thermal simulation experiments of transitional shale in the Shan23 Submember doi:10.57760/sciencedb.cjxb.0001o en The thermal simulation of the closed system of the golden tube was conducted using the Shanxi Formation low mature black shale in the Bolougou section under a constant confining pressure of 50MPa, with pressure fluctuations kept within 0.5MPa during the experiment. The sample was rapidly heated from room temperature to 312 ℃, and then further heated to 600 ℃ at a heating rate of 2 ℃/min. A total of 12 target temperature points were set, with adjacent temperature intervals of 24 ℃, and each temperature point was kept at a constant temperature for 8 hours. The simulation experiment covered the low to over mature stage, corresponding to EasyRo of 0.62% -4.45%. After the experiment, the hydrocarbon products were separated and quantified to obtain the yields of liquid and gaseous hydrocarbons at different maturity stages, which were used to restore the hydrocarbon generation and evolution process of the Shanxi Formation marine continental transitional shale. Semi closed pressure thermal simulation was conducted using low mature black shale from the same source as the gold pipe experiment in the Bolougou section. The experiment used the DK-III type formation pore thermal pressure hydrocarbon generation and expulsion simulator, with six temperature points set at 325 ℃, 350 ℃, 375 ℃, 425 ℃, 500 ℃, and 575 ℃. The static rock pressure was 50-100 MPa, and the sample was heated to the target temperature at a rate of 1 ℃/min and kept at a constant temperature for 8 hours. The EasyRo values for the samples at different experimental stages were 0.87%, 1.07%, 1.45%, 1.96%, 2.79%, and 3.77%, respectively. After the experiment, residual samples at different stages of thermal evolution were subjected to CO2 adsorption, N2 adsorption, and high-pressure mercury intrusion testing to obtain pore structure parameters for micropores, mesopores, and macropores.  Shanxi Formation; thermal simulation; shale Xingcheng Zhu Li Yong Lu Jungang PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
