摘　　要：构造-层序地层特征是储层精细研究及岩性油气藏勘探的基础。通过对南堡凹陷高柳地区三维地震与钻(测)井资料的解释,研究沙三段沉积期的区域构造、断裂演化及沉积层序发育特征,进一步明确构造对沉积层序发育的控制作用。结果表明:沙三段沉积期,裂陷沉降与沉积充填过程中存在构造抬升和断裂掀斜等作用,形成了该裂陷期内的3个"裂陷拉张-快速沉积-抬升剥蚀"旋回,其控制了3个亚构造层的沉积层序旋回特征。西南庄断层与柏各庄断层构造活动的横向差异造成了沙三段"跷跷板"式交错增厚的地层充填模式。区内构造地貌演化控制了沉积体系的类型、纵向叠置样式与横向展布特征。The structure-sequence stratigraphy characteristics are necessary for subsequent study of lithologic reservoirs.Based on the 3D seismic and logging data, the regional tectonic evolution, fault development and tectonic sequence stratigraphy characteristics of the third member of Shahejia Formation（E s3） were studied, and the tectonic effect on sequence stratigraphic configuration was analyzed. The result shows that tectonic uplift and fault tilting activities occurred during the rifting process of the E s3 depositional period, which formed three ＂rifting and subsidence-rapid deposition-uplift and erosion＂ tectonic-stratigraphic cycles and corresponding three sub-structural units. The tectonic activities controlled the sedimentary sequence features of each sub-structural unit. The lateral differences of Xinanzhuang-Baigezhuang fault activities led to ＂see-saw＂ sedimentary filling characteristics of E s3. Tectonic geomorphology influenced the sedimentary system types, vertical superimposed styles and horizontal distribution characteristics.
