Research Progress and Development Trend of Natural Gas Caprock

Abstract

Abstract: The research progress of natural gas caprock at home and abroad in recent years is reviewed, including caprock classification, sealing mechanism, controlling factors of the sealing ability, experimental technologies and geophysical research methods as well as comprehensive evaluation of its sealing ability, etc. The controlling effects of caprock on natural gas accumulation are analyzed, and the development trend of natural gas caprock research is predicted. Finally, it is suggested that strengthening research on natural gas caprock development trend of natural gas caprock research is predicted. Finally, it is suggested that strengthening research on natural gas caprock is of great theoretical and practical significances for perfecting gas accumulation geological theory and guiding natural gas exploration.

Key words: Natural gas caprock, research progress, sealing mechanism, quantitative research method, comprehensive evaluation, natural gas accumulation, development trend
