【 摘 要 】

with the development of society, the traditional energy is becoming more and more scarce. The emergence of natural gas has attracted worldwide attention. It is a new clean energy that may replace traditional energy in the future. In the permafrost of Qiangtang basin, the audio magnetotelluric data processing and interpretation for the investigation of natural gas hydrate were carried out. Based on the interpretation and processing, combined with the geological and two-dimensional seismic reflection and geophysical data in the study area, we made a comprehensive research and analysis. The geophysical and hydrocarbon anomalies related to gas hydrates are obtained in the study area. Through the comprehensive analysis of the audio magnetotelluric data and seismic data, we have obtained the data of the electrical and fracture structures in the study area. This provides a scientific basis for the detection of natural gas hydrates in permafrost regions of Tibet plateau, Qinghai, and confirms the reliability of applying geophysical methods to explore natural gas hydrates.
