Abstract: Based on determining the property of the tectonic activity of the Xuefeng Mountain， according to the
original petroleum geology condition， post-destruction of oil and gas and sub-generating characteristics of reser-
voirs in western Hunan and Hubei， and central Hunan regions， this paper explores the tectonic controls of Xuefeng
Mountain Activities on the distribution of marine oil and gas in adjacent areas. Studies show that the Caledonian
movement and Yansian movement were the most powerful two intracontinental orogenic events in the Xuefeng
Mountain region， and the regional disparity of tectonic deformation has led to the differences of geology charac-
teristics and distribution of marine oil and gas on both sides. The maturity of source rocks of lower assemblage in
western Hunan and Hubei provinces are high over-mature， and the component is mainly dry gas， and they mainly
gather in structural-lithologic compound traps， where the plugging condition are better in synclinorium. The marine
oil and gas of the Hunan regions gather in upper assemblage， and the source rocks are mature-over-mature. The
ancient anticline under Longtan Formation coal-bearing cap rock and the sub-anticline within adjacent syncline are
more favorable for oil and gas sub-aggregation.

Key words: Xuefeng Mountain, west Hubei and Hunan, middle Hunan depression, slumped overthrust structure, marine oil and gas
