| 英文摘要 | Electric heating technology is a vital method for in-situ modification and exploitation of oil shale. This process subjects the wellbore and cement sheath to prolonged exposure to high temperature and pressure environments, posing significant challenges to the integrity of the cementing seal. To investigate the thermally induced changes during the electric heating process of cement sheath and oil shale, a combined model of cement sheath and oil shale was established using the discrete element method. The combined model was calibrated based on macroscopic mechanical experiments of cement sheath and oil shale. Subsequently, the thermal-mechanical coupling problem and thermal cracking phenomenon of the combined model under high temperature and high pressure environments were examined. The results revealed that thermal cracks begin to emerge at the onset of heating at around 150 degrees C, leading to a decrease in compressive strength and elastic modulus of the combined body. As the temperature reaches 400 degrees C to 500 degrees C, the number of thermal cracks peaks. The underground high-pressure environment impedes the thermal expansion of combined body particles, thereby inhibiting the development of thermally induced cracks. The addition of steel fibers to the cement sheath significantly reduces thermal cracking and effectively enhances the sealing performance of the cement sheath. |
