| 摘 要： | 南堡凹陷为渤海湾盆地的一个新生代富生烃凹陷，内部断层十分发育，大量的油气藏都围绕断裂分布。根据断裂平面及剖面组合特征，断裂平面组合样式可分为4种：平行状、交织状、梳状和帚状；剖面组合分为3种：复“y”形组合、花状组合及阶梯式组合。根据断裂、砂体及油气藏的分布特征，发现二级和三级生长断层凹面储集厚度较大、且砂体孔渗性较好，是油气运移的主要方向。反向旋转断层组合的断层下盘和同向旋转断层组合的断层上盘是油气聚集的有利部位。但由于断层带的分带性，上诱导裂缝带相对下诱导裂缝带渗透性好。上诱导裂缝带利于油气运移，下诱导裂缝带利于封堵油气，油气的最有利聚集部位为反向旋转断层组合的下盘。

| Abstract: | There are large amount of faults in Nanpu depression which is a Cenozoic hydrocarbon rich depression in Bohai Bay Basin, and a large number of pools accumulated around faults. Assemblage styles of fault both in plane and section were analyzed in this paper. Faults of Nanpu depression can be classified into four styles in plane： parallel, interlaced, pectinate, and fastigiated style; three fault assemblages in section including complex ＂y＂, flower structure and ladder pattern. According to the analysis of distribution of faults, sand bodies and hydrocarbon reservoirs, it has been found that concave of second to third order growth faults are the principal orientation of oil migration, where thick and high porosity and high permeability reservoirs were obtained. Down-dip block of contrarotation faults and upfaulted block of homodromous faults are the favorable oil accumulation locations. Fault zone can be divided into three parts： up-induction-fracture, middle crush, and down-induction-fracture zone. The up-induction-fracture zone owns higher permeability than down-induction-fracture, so the former is favorable place of oil migration and the latter inclines to be plugged zone. |
