Abstract: Songliao Basin is a typical continental sedimentary basin. The region still has a certain quantity of oil and gas resources for exploration though it has been brought under oil and gas exploration and development for more than half a century. However, these oil and gas reservoirs are low in abundance and poor in physical properties, belonging to compact oil reservoirs. It is necessary to make technological creation and establish the new principles for exploration and development. Usually, a large-scale sedimentary basin has a variety of elements for existence of resources. Songliao Basin is no exception. The basin is also rich in geothermal resources. All the strata outside the oil and gas zone have the geothermal reservoirs at various levels, which need to be brought under exploitation. In addition, the basin has some suspicious resources to be identified through the exploration efforts. A low-resistivity zone with a huge thickness exists in the deep position of the basin. The only explanation for this zone is that “a certain matter is contained in the rock.” Such “contained matter” is likely to gas. What kind of gas it is needs to be further studied. An abundance zone of uranium is likely to exist along the Bayan-Tieli-Bei’an line on the eastern periphery of the basin. If a uranium mine is found in this area, its value is far higher than petroleum. It is worth making an exploration effort.
