二连盆地上古生界海相碎屑岩和碳酸盐岩沉积建造发育，容矿地层无区域变质作用，暗色泥岩和碳酸盐岩烃源岩发育。通过地质研究和对烃源岩的初步分析评价，可划分出6个烃源层（尼丘河、本巴图、阿木山、寿山沟、哲思、并确定了几套有利的生储盖组合，确定了暗色泥岩的烃源岩标准二连盆地暗色泥岩（灰岩）为中-好，有机质类型为Ⅱ2-Ⅲ型，热演化程度为成熟-凝析油和湿气，具有较高的生烃潜力，可作为二连盆地新的勘探重点层系。
In Erlian basin,Neopaleozoic marine-paralic clastic and carbonate sedimentary formation developed well.The host formation has no regional metamorphism.The dark mudstone and carbonate source rock well developed.Based on the geological research and the primary analysis and evaluation of source rock,six source formations(Niqiuhe,Benbatu,Amushan,Shoushangou,Zhesi,Linxi) and several profitable source-reservoir-caprock assemblages are determined.The source rock standard of the dark mudstone(limestone) is moderate-good.The organic material is classified in Ⅱ2-Ⅲ type.Thermal evolution degree is mature-condensate oil and humidity.The dark mudstone(limestone) is in high potential of hydrocarbon and can be taken as the new crucial exploration formation in Erlian basin.
