摘　　要：在地层资料分析的基础上,运用平衡剖面技术,选取松辽盆地东缘宾县凹陷的4条南北走向测线,对其地震解释剖面进行平衡复原,并进行伸展量、伸展率和伸展速率计算。分析认为,宾县凹陷经历了断陷构造期、断坳转化期、坳陷构造期和反转构造期4个演化阶段。结果显示,宾县凹陷在断陷期和断坳转化期的伸展速率较大,分别约为0.21和0.2 mm/a,且宾县凹陷的次级构造单元宾县洼陷的中部变形强于边缘。Based on strata data analysis, with balanced cross-section technique, choosing 4 NS-trending cross-sections in the Binxian Sag in the east of Songliao Basin, seismic analysis sections are restored in this paper. Extension quantity, rate and velocity for each evolution stage are calculated. The Binxian Sag has experienced at least 4 evolution stages： fault, fault-depression, depression and tectonic inversion. Results have indicated that, extension velocities during the fault and fault-depression stages are higher, about 0.21 and 0.2 mm/a respectively. Deformation intensity in the center of Binxian sub-Sag is stronger than the margin.
