兴凯湖盆地是与敦密断裂构造活动密切相关的含煤盆地，发育古近系虎林组和新近系富锦组含煤地层。利用实测剖面、钻孔岩心及测井曲线资料，对该盆地含煤地层沉积环境、层序地层及聚煤特征进行研究，在研究区识别出三角洲沉积体系和湖泊沉积体系。根据研究区内的岩性岩相变化，将区内含煤地层划分为2个三级层序Sq1和Sq2,其中层序Sq1相当于古近系虎林组，发育湖侵体系域和高位体系域，层序Sq2相当于新近系富锦组，发育低位体系域、湖侵体系域和高位体系域；古近纪主要聚煤环境为高位体系域的三角洲平原沼泽，新近纪聚煤环境为低位和湖侵体系域的滨浅湖淤浅沼泽和高位体系域的三角洲平原沼泽。

The Lake Xingkai Basin is a coal-bearing basin closely related to tectonic activities of the Dunhua-Mishan fracture zone, de?veloped Paleogene Hulin Formation and Neogene Fujin Formation coal-bearing strata. Using data from measured sections, drilling cores and logging traces, have carried out studies on coal-bearing strata sedimentary environment, sequence stratigraphy and coal accu?mulation features, recognized delta and lacustrine sedimentary systems. According to lithologic and lithofacies variation in study area, divided coal-bearing strata in the area into 2 third-order sequences Sq1 and Sq2, the former is corresponding to Paleogene Hulin For?mation, developed lacustrine transgressive and highstand systems tracts;while the later corresponding to Neogene Fujin Formation, de?veloped lowstand, lacustrine transgressive and highstand systems tracts. Paleogene main coal accumulation environment was highstand systems tract delta plain bog;Neogene coal accumulation environments were lowstand and lacustrine transgressive systems tracts lake shore, shallow lake silting bog and highstand systems tract delta plain bog.
