通过对兰聊陡岸带地质地震相综合研究认为， 陡岸带存在一系列呈裙带式分布的扇体。受断裂活动、物源方向的影响， 纵向上、横向上扇体规模、储层特征、成藏规律都有明显差异。横向上， 北段扇体比南段扇体发育； 纵向上， 毛岗地区下第三系沙三段２ 、３ 层、前梨园地区下第三系沙三段１～４ 层、白庙地区下第三系沙三段３ 、４ 层扇体较发育， 这些扇体的扇中部位是油气藏勘探的有利部位。
Based on a comprehensive study of the geological facies in the Lanluo steep bank, there are a series of fan-shaped fan-shaped bodies distributed in the steep bank. Influenced by the fault activity and source direction, there are obvious differences in fan size, reservoir characteristics and reservoir forming pattern in vertical and horizontal directions. In the horizontal direction, the fans of the northern segment are more developed than the segments of the southern segment. In the longitudinal direction, the second and third members of the Lower Third Member of the Shahejie Formation are located at the second and third floors and the third to fourth members of the third member of the Shahejie formation in the Qianliyuan area. The 3rd and 4th strata of the third member of the Lower Tertiary are more developed, and the mid-fan of these fans is a favorable site for oil and gas exploration.
