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.

摘要： 松辽盆地是一个典型的陆相沉积盆地,经过半个多世纪油气资源的勘探开发,目前仍有相当数量的油气资源有待勘探,只是这些油气藏含油丰度低、储层物性差,属致密油藏,因此,在勘探开发的思路和技术上需要创新。一个大型沉积盆地,其资源的赋存往往呈多元性,松辽盆地也不例外。盆地地热资源丰富,储量巨大,在含油区以外的各区地层均有不同程度的地热储集,有待充分开发利用。此外,盆地还有一些可疑资源也有待探索。盆地深部存在一个巨厚的低阻带,其形成的唯一解释是"岩层中有某种含有物",这种"含有物"有可能是气体,是何气体需要进一步探查。在盆地东部边缘沿巴彦—铁力—北安一线可能存在铀元素的富集带,并有可能具备成矿条件,如能成矿,其经济价值远优于石油,值得探索。
