摘　　要：阜新盆地是辽西地区的一个晚中生代小型断陷盆地，形成于晚侏罗世到早白垩世期间。经研究表明，盆地剖面形态为典型的地堑式，平面上为北北东走向，呈向北西凸出的弧形。两侧的边界断裂在成盆期内发生了剪切走滑、挤压逆冲和拉张裂陷等复杂的构造变形；盆地内形成了一系列与边界断裂斜交的雁行状背斜和洼陷以及多组断裂构造。主要的控油构造样式有入字型、雁行状、铲形正断层滑脱断阶、铲形正断层滚动背斜等。圈闭类型主要有背斜、断鼻和断块等，分布于生油洼陷周围，非常有利于油气聚集。Fuxin basin is a small sized rift subsidence basin of later Mesozoic in western Liaoning province. It formed in J 3K 1. The shape of the basin is a typical graben in cross section of the basin. The strike of the basin is NNENE, the strike line of the basin is an arc line bulging toward the NNW. The shearing, compressional and extensional movements of the boundary faults of its both sides brought out during J 3K 1. Some folds and faults formed in the basin. These folds and faults crossed over a number of strctural systems, and the main oil control structures include faults and folds in “λ”type and echelon, listric normal fault slip faults, listric normal fault rollover anticline. Oil gas traps are mainly anticline, nose structure and faultblock. These traps are located all around of oil source depression, which is favourable to the accumulation of oil gas.
