摘要： 综合利用钻井岩心、测-录井、三维地震等方面资料，对东海盆地西湖凹陷保俶斜坡带北段古近系平湖组与宝石组含油气地层的层序特征、断层的构造组合特征进行了分析；通过DepoSpace沉积域建模、层序地层界面差值法等对古地貌进行了恢复，基于古地貌的倾角属性，对坡折类型进行了量化分类，并探讨了不同类型坡折的控砂机制。研究结果表明：①西湖凹陷保俶斜坡带北段古近系宝石组—平湖组自西向东划分为近隆山、隆翼山及远隆山3个构造带，共识别出7个三级层序，其中宝石组3个，平湖组4个。研究区断层发育，可划分为滑动断阶、平行断阶、堑垒组合、似花状构造及“Y”字形组合5类断层组合样式。②研究区坡折可分为断裂坡折（Ⅰ级）、地貌坡折（Ⅱ级）及沉积坡折（Ⅲ级）3类，其控砂机制各不相同，断裂坡折受构造断裂影响显著，地貌坡折受构造挠曲和沉积改造共同作用，而沉积坡折以沉积侵蚀作用为主。③研究区发育近隆山堑垒断层组合的断裂-地貌坡折帚状控砂模式、隆翼山—远隆山地貌-沉积坡折控砂模式、隆翼山—远隆山多级断阶断裂坡折控砂模式、近隆山—远隆山平行断槽断裂坡折控砂模式等4种。④研究区坡折控制着沉积体发育，Ⅰ级坡折下盘常发育滑塌较远的滑塌沉积，Ⅱ级坡折下盘常发育陡坡沉积，Ⅲ级坡折下盘常发育缓坡沉积；分支水道常流经Ⅱ，Ⅲ级坡折倾角较小的部位，流经Ⅰ，Ⅱ级坡折时易在坡脚形成坡积扇。

Abstract: Sequence characteristics and structural combination characteristics of faults of the oil and gas bearing strata of Paleogene Pinghu-Baoshi Formation in the northern section of Baochu slope zone of Xihu Sag in East China Sea Basin were studied by using drilling core，logging and 3D seismic data. The paleogeomorphology was restored through DepoSpace sedimentary domain modeling and sequence stratigraphic boundary difference method. Based on the dip attribute of paleogeomorphology，the types of slope breaks were quantitatively classified，and the sand control mechanisms of different types of slope breaks were explored. The results show that：（1）Paleogene Baoshi-Pinghu Formation in the northern section of Baochu slope zone in Xihu Sag was divided into three structural zones from west to east： the Jinlong Mountain，Longyi Mountain，and Yuanlong Mountain. 7 thirdorder sequences have been identified，with 3 in Baoshi Formation and 4 in Pinghu Formation. In the research area，faults develop and can be divided into 5 fault combination patterns， such as sliding fault step，parallel fault step，graben barrier combination，flower like structure，and“Y” -shaped combination.（2）The slope break in the research area can be classified into fault slope break（level Ⅰ），landforms slope break（level Ⅱ）and sedimentary slope break（level Ⅲ）. The sand control mechanisms of the 3 types of slope break are different. Fault slope break is significantly affected by structural fault，landforms slope break is affected by both structural bending and sedimentary transformation，while sedimentary slope break is mainly affected by sedimentary erosion. （3）4 types of sand control patterns develop in the research area，including fault-landforms slope break broom shaped sand control pattern of the graben barrier fault combination of Jinlong Mountain，landforms-sedimentary slope break sand control pattern of Longyi-Yuanlong Mountain，multi-stage broken step fault slope break sand control pattern of Longyi-Yuanlong Mountain，parallel fault trough fault slope break sand control pattern of Jinlong-Yuanlong Mountain.（4）In the research area， the slope breaks control the development of sedimentary bodies. The footwall of level Ⅰ slope breaks often develop landslide deposits with distant landslides，the footwall of level Ⅱ slope breaks develop steep slope deposits，and the footwall of level Ⅲ slope breaks develop gentle slope deposits. Branch waterways often flow through the area with smaller slope angles on level Ⅱ and Ⅲ slope breaks， and they are prone to form slope fans at the foot of level Ⅰ and Ⅱ slope breaks when flow through them.

Key words: paleogeomorphology restoration, fault slope break, landforms slope break, sedimentary slope break, sand control mechanism, Pinghu Formation, Baoshi Formation, Paleogene, northern section of Baochu slope zone, Xihu Sag
