This paper analyzes the relationship between structures and oil-gas preservation through detailedly surveying structural features. The extentional direction, model and property of the each structural trace are analyzed and the authors studied their relations one by one. Research results show the Tuonamu River fault  and dome structure  greatly effect oil-gas preservation conditions in this area. By confirming sequence time between the tectonic stress and reservoir-formation period, and geological structures influencing preservation, the authors evaluated correctly tectonic conditions in the research area.
