Abstract: Deep-buried volcanic reservoirs, which are different from sedimentary reservoirs, are characterized by special formation environment and distribution: with high temperature and high pressure. Volcanic reservoirs, which are inversely correlated with the thickness of volcanic rocks, have better reservoir properties than the clastic reservoirs, and the porosity and Permeability of reservoirs are less influenced by their buried depth. These reservoirs are predominant-lycontrolled by lithological factors, with the most favorable hydrocarbon accumulation zone located in the thinning belt of volcanic rocks towards sedimentary rocks. Undoubtedly, such distribution peculiarity of deep-buried Volcanic reservoirs can contribute to the discovery of similar reservoirs.
