Abstract

Abstract:

On the basis of 2D seismic data, the structural characteristics and reservoir-forming condition of No.Ⅱ fault zone in Tazhong area were investigated using the structural factor pertinence method and structural analysis. It is indicated that No.Ⅱ fault zone in Tazhong area can be divided into many sections. The main faults in the different sections have different deformation scale. Under the control of extensional faults formed before the Late Cambrian, the gypseous halite flowing and thickening activities appeared in the local area of the Middle Cambrian,which influenced the process of structural deformation in the upper stratum. The main fault of No.Ⅱ fault zone in the Tazhong area was developed from the Middle Ordovician to the Late Ordovician. Owing to the compact of gypseous halite in the Middle Cambrian, both over and under the gypseous halite developed two groups of high-quality dolomite reservoir. Under the influence of buckling activity, the structural or lithologic traps were developed at slope area over gypseous halite. So, the dolomite preferable reservoir over gypseous halite is a prospect exploration target. The periclinal belt around the buried mountain, which universally developed in No.Ⅱ fault zone of Tazhong area, has an advantageous prospect for large-scale oilfield.

Key words: Tazhong area, fault zone, segmentation, structural characteristics, hydrocarbon accumulation condition, exploration prospect

摘要：

根据二维地震资料解释成果，利用构造要素相关性分析及构造解析方法，探讨了塔中古隆起塔中Ⅱ号断裂带的构造特征，并分析了该断裂带的油气成藏条件。研究结果表明：塔中Ⅱ号断裂带在横向上具有分段性，不同区段的主逆冲断裂规模不同。塔中Ⅱ号断裂带演化受到晚寒武世之前张性断裂的控制，中寒武统膏盐岩在局部地区发生的较明显塑性流动和聚集增厚，影响了上覆地层的构造变形过程，主断裂于中奥陶世末—晚奥陶世发育。由于中寒武统膏云岩段分隔，寒武系发育盐上、盐下两套白云岩优质储层。在盐上斜坡区，受构造翘倾活动影响，可能会发育构造或岩性圈闭，因此盐上白云岩优质储层可成为良好的勘探目标。在塔中Ⅱ号断裂带普遍发育的古潜山圈闭中，其潜山围斜带可能是寻找大油气田的有利目标。
