摘要

Based on the new insight into the volcanic sequence coupled with associated theory and technique innovation, large volcanic gas fields were successfully found in the Songliao Basin, NE China. Volcanic rocks have thus been changed from the “forbidden zone” to the “target” in oil and gas exploration there. This has promoted the volcanic exploration of China and brought rapid growth of petroleum reserves in recent years. Compared with sedimentary rocks, volcanics in deep of the basin have three major advantages including large volume, little change of reservoir space with depth of burial, better porosity and permeability. Various volcanic rocks can become effective reservoirs. Volcanic oil and gas exploration is just at the preliminary step globally. Their resource potential has been greatly underestimated up to now. The authors therefore believe that volcanic reservoirs will certainly become important field of oil and gas exploration in the near future.
