摘　　要：松辽盆地石炭 二叠系是烃源岩,沉积埋藏史可划分出持续深埋型、平衡埋藏型和短暂浅埋型3种类型。早白垩世晚期,石炭 二叠系烃源岩地温又一次达到并超过90℃,开始第二期生烃,油、气并生。这一时期,有效供烃区位于盆地东南部农安地区、西北部黑鱼泡地区,生气强度超过了生油强度。通过对石炭 二叠系沉积埋藏史、有机质热演化史和生烃史研究,无论对于深层找气,还是对盆地中新生代地层的油气勘探都具有十分重要的地质意义。The CarboniferousPermian source rocks are ubiquitous in the Songliao Basin. The depositional and burial history of the source rocks may be divided into three types: steadly deep burial, equilibrium burial and ephemeral shallow burial types. The geotemperatures of the source rocks went once again up to or exceed 90℃ during the late Early Cretaceous, resulting in the second stage of the oil and gas generation in the basin. During this period, the gasgenerating intensity was greater than the oilgenerating intensity. The valid source areas include the Nongan district in the southeastern part and Heiyupao district in the northwestern part of the basin. This paper focuses on the modeling and reconstruction of the depositional and burial history, organic matter thermal evolutionary history and hydrocarbon generation history of the CarboniferousPermian source rocks with the aid of basin simulation. The results in the study are believed to be important to the gas exploration in the deeper levels and the oil exploration in the Mesozoic and Cenozoic strata.
