摘　　要：辽河盆地目前发现 7个反转构造带 ,均呈北东或北北东向展布 .正反转构造可分为单一型和复合型 2大类 .因受力方式的不同 ,单一型正反转构造可分为挤压倾滑型和压扭型 2亚类 ,复合型正反转构造分为压扭复合型和挤压倾滑复合型 2亚类 .这些反转构造均经历了裂陷—坳陷—反转的 3个发展阶段 .纵向上正反转构造的幅度均小于拉张期的构造幅度 ;平面上由于受力方式和力的大小差异 ,各个带正反转构造的类型和强度因此不同 .正反转构造直接覆于凹陷之上 。There are 7 inverted structural belts in Liaohe Basin, and they all show east north direction. The structures can be divided into 2 kinds: single type and composite type. The single type can also be subdivided into 2 subtypes: compressional dip slip one, and compressional wrench one. The composite type can be subdivided into 2 subtypes: compressional and dip slip composite one, and compressional and wrench composite one. The inverted structures have gone through extension. Vertically, the magnitude of positive inverted structures is less than that of the structures in extension stage, and because the magnitude and acting manner of the force laterally exerting on the structures are different, the types and intensity of the positive inverted structures are different. The positive inverted structures locate above the depression, which is favorable to the migration and accumulation of oil and gas.
