本文综合了近年来对松辽盆地（重点是北部地区）石油地质研究的成果，将主要的认识进行了总结，包括白垩系为陆相沉积的论证、盆地的性质和演化阶段、中新生界的构造特征、陆相生油的主要特征和油气形成阶段、大型湖盆的沉积特征和各种相带的砂体形态、粘土矿物的纵向演化规律和成岩阶段等，最后总结了控制油气聚集的基本规律，指出松辽盆地不仅存在着比较简单的背斜构造油气藏，而且也存在着多种比较复杂的油气藏。
In this paper, we summarize the main achievements of the research on petroleum geology in the Songliao Basin (focusing on the northern region) in recent years, including the demonstration of Cretaceous continental deposition, the nature and evolution of the basin, the Mesozoic-Cenozoic Tectonic features, the main features of terrigenous oil, the stages of oil and gas formation, the sedimentary characteristics of large lake basins, the sand body morphology of various facies belts, the longitudinal evolution of clay minerals and the diagenetic stage. Finally, the basic laws governing hydrocarbon accumulation It is pointed out that not only the relatively simple anticlinal tectonic reservoirs exist in the Songliao Basin, but also many more complex reservoirs.
