摘要: 对四川盆地飞仙关组台缘带鲕滩分布规律的认识不清,极大地制约着该区鲕滩气藏的勘探开发成效.以四川东北部飞仙关组为例,分析台缘带鲕滩的发育特征, 探索其分布规律.研究发现区内飞仙关组鲕滩沿台地边缘呈NW向展布,并在NE、NW两组基底正断裂交叉处向台地内部呈指状延伸,其延伸方向与台地边缘近于垂直.讨论认为基底断裂同沉积活动形成的古地理格局、沉积古地貌与相对海平面的升降变化共同控制了该区飞仙关组台缘带鲕滩的纵、横分布规律.指出NW向基底断裂的同沉积张裂活动形成了台坳分异的沉积格局,控制了台缘带及台缘带鲕滩相带展布;NE向基底断裂的同沉积正断活动加剧了台地边缘带的沉积地貌分异,台缘带鲕滩发育于NE-SW向基底断裂“断隆”地貌高地,并向台地内部延展,形成“北西控带、北东修饰”的断控型台缘鲕滩指状窄相带分布规律.考虑相对海平面升降变化对鲕滩沉积厚度及沉积范围的叠加影响,总结了台缘鲕滩的分布模式.Abstract: To better probe the laws of distribution of oolitic shoal which lies in the platform margin of Feixianguan Formation, Sichuan basin to facilitate the exploration and development on the oolitic shoal gas pool, this paper analyses the development properties and distribution law of platform margin shoal by means of case study of northeastern region of Sichuan basin, after which it points out that this type of oolitic shoal expands in the direction of NW-SE along the platform margin and stretches in "finger-shape" to the platform interior from which two groups of positive faults basement cross in directions of NE and NW, while the extension direction of the "finger-shape" is vertical to the platform margin. Furthermore, paleogeography framework formed by syndepositional activities of basement cracking, sedimentary paleogeomorphology and relative sea level change dominates the longitudinal and horizontal discipline of this oolitic shoal jointly. First, syndepositional tension of basement cracking in the direction NW contributes to the sedimentary framework of platform-hollow differentiation, which simultaneously controls the distribution of platform margin and also facies of oolitic shoal on it., while that of NE one aggravates the degree of differentiation of sedimentary geomorphy in the researching area. Oolitic shoal of platform margin occurs on the "cracking uplift" highland formed by the basement cracking in the direction of NE-SW, which migrates to the internal platform, characterized by the fault controlling oolitic shoal of platform margin fingered slim zone of "belts dominated by NW, decorated by NE". Second, the relative eustasy regulates sedimentary thickness and scale. Consequently an integration model of multi-factor on the shoal of platform margin can be established eventually.
