Abstract: The Sichuan Basin, a major oil and gas producing region in China, has accumulated extensive geological, seismic, and drilling data, providing a strong foundation for regional geothermal energy development. Despite this informational advantage, geothermal resources within existing oil and gas wells remain largely underutilized. Focusing on the Moxi area, identified as having significant geothermal anomalies, this study prioritizes the deeper, higher - temperature, and thicker Longwangmiao Formation reservoir, as reservoir temperature and depth are crucial for the economic viability of geothermal projects. A three-dimensional geological model of the reservoir was constructed, and the one-dimensional steady-state heat conduction equation was used to estimate the internal temperature distribution. Results show that the Longwangmiao Formation reservoir in the Moxi area has temperatures ranging from 104 ℃ to 154 ℃ . The total geothermal resource is estimated at 2. 04 × 10¹⁰ J (equivalent to 696 million tons of standard coal), with a recoverable portion of 3. 06 × 10⁹ J (104 million tons of standard coal). Based on these findings, a development strategy is proposed: prioritize direct use or ORC power generation,utilize power generation tailwater for drying applications, and implement cascade utilization of geothermal energy. Future research should explore the integration of geothermal with other renewable energy sources to support large - scale geothermal power generation and provide technical reserves for sustainable energy development.
