摘　　要：阜新盆地煤、煤层气、石油、致密砂岩气、地热等多种能源矿产的分布和成藏受到盆地构造热演化的控制。纵向上,煤和煤层气主要集中在盆地上部地层,石油和致密砂岩气主要集中在盆地中部地层,地热主要集中在盆地底部地层。平面上,石油位于盆地中部和中南部,致密砂岩气位于盆地中部的东梁构造带,煤炭全盆地均有分布,主要可采煤层位于盆地中部,煤层气位于盆地中部,地热位于盆地中部的东梁构造带。盆地构造热演化与能源矿产的时空配置表明,盆地的构造热演化控制了盆地能源矿产的成藏,煤是多能源矿产重要的物质来源,盆地多能源矿产成藏顺序依次为:煤→石油→致密砂岩气→煤层气→地热。综合以上特征,阜新盆地多能源矿产的联合勘探开发应以东梁构造带、清河门—艾友构造带、王营—刘家构造带为主要勘探区域进行。To prospect for the energy resources in the Fuxin basin, the distribution and formation of energy resources including coal, coalbed methane, oil, tight gas sand and geothermal resources were studied. Vertically, the coal and coalbed methane mainly distribute in up layer of stratum; oil and tight gas sand mainly distribute in middle layer of stratum; geothermal resources mainly distribute in substratum. Laterally, oil mainly distributes in the center of the basin; tight gas sand and geothermal resources distribute in Dongliang tectonic zone; coal distribute in all parts of the basin but the available coal seams and coal bed methane mainly distribute in the center of the basin. Though analyzing the relationship between these resources and tectonic evolution, it shows that The tectonic evolution controls the formation of the energy resources and the coal is the most important source of hydrocarbon. Therefore, these resources accumulate in a sequence of coal→oil→tight gas sand→coal bed methane→geothermal resources. In sum, The Dongliang, Qinghemen-Aiyou and Wangying-Liujia tectonic zone are favorable for joint exploration of the multi-energy resources. basin.
