| 摘 要： | 松辽盆地南部-辽西地区横跨兴蒙-吉黑造山带、华北地台及其北缘的增生带几个大地构造单元。受不同类型基底和区域断裂控制，在辽西盆岭区、松辽盆地区和辽北盆地区发育不同类型的晚三叠世-早侏罗世、中-晚侏罗世、白垩纪盆地，各期盆地间继承性较差，方向性极强。三叠系烃源岩发育程度较差，下侏罗统、下白垩统2套煤系地层是主要烃源岩发育段。侏罗系北票组是朝阳-北票等盆地的重要烃源岩，白垩系烃源岩发育较好，除九佛堂组、沙海组、阜新组3套烃源岩外，义县组发育潜在烃源岩。盆地含油气性评价表明辽北盆地区发育4种不同级别的含油气盆地，其中以陆家堡断陷、钱家店断陷、昌图断陷和茫汉断陷勘探前景最好；辽西地区阜新-义县盆地、朝阳-北票盆地等具有一定的勘探价值。

| Abstract: | The south area of Songliao Basin and west area of Liaoning tretch across several geotectonic units such as Xingmeng-Jihei orogen,North China Platform,and increased convergent plate boundary in north border of North China Platform.In Liaoxi basin-and-range province,Songliao Basin province,and Liaobei basin province,a series of different types of basins in Late Triassic,Middle-Late Jurassic,Cretaceous basins were developed under the control of different types of basements and regional faults.Basins in different periods evolved discontinuously,and directions of these basins are very obvious.Source rocks in Triassic are not well,and two suits of coal-bearing strata in Lower Jurassic and Lower Cretaceous are main source rocks.The Beipiao Formation in Jurassic is important source rock in the Chaoyang-Beipiao basins etc.The development of Cretaceous source rocks are better,there also develop potential source rocks in Yixian Formation except three sets of source rocks,Jiufutang Formation,Shahai Formation and Fuxin Formation.The basin hydrocarbon assessment indicated that there grow four different grades of hydrocarbon basins in Liaobei basin,the exploration prospects of the Lujiapu fault depression,Qianjiadian fault depression,Changtu fault depression,Manghan fault depression are best,and Fuxin-Yixian basin,Chaoyang-Beipiao basin have a certain exploration prospect in Liaoxi area. |
