| 摘 要： | 综合运用高精度层序地层学、构造一地层学方法，认为十屋断陷深层发育的各类隐蔽圈闭是下一步勘探工作的重要目标。同时，由于构造对沉积的控制作用，在断陷内部不同的构造部位具有不同的隐蔽圈闭分布特征。十屋断陷西部皮家地区、北部张家屯一八屋地区位于油气主要运移指向区，分别由断裂坡折带和以挠曲型褶皱为特征的弯折带控制的储集砂体十分发育，盖层及保存条件也十分优越，是深部原生岩性、地层油气藏最有利的勘探目标区带。

| Abstract: | Based on high-resolution sequence stratigraphy and tectono-stratigraphy, subtle traps are considered as the key exploration targets in Shiwu fault depression in the future. Sediments controlled by structure, and there are different distribution characters of subtle traps in different structural positions of the deep strata of Shiwu fault depression. Pijia and Zhangjiatun-Bawu areas are in the vicinity of hydrocarbon generating center and are located in the directions of petroleum migration. Abundant reservoir sandstones are respectively controlled by fault slope-break and bend slope-break developed here and the sealing and preservation conditions are also very well. So they are the most favorable and realistic exploration zones in the deep strata. |
