| 摘 要： | 断裂带是具有复杂结构的三维地质体,其内部可以划分为低渗透性的滑动破碎带、高渗透性的诱导裂缝带等具有不同物性特征的结构单元类型;受各种地质条件和因素的控制,不同性质及活动强度的断裂带、断裂的上下盘、同沉积断裂的不同深度,其断裂带内部结构特征存在差异,这导致了断裂具有对油气输导、封堵的双重性和时空差异:诱导裂缝带可成为油气运移的通道,而滑动破碎带则具有较强的横向分隔性;同沉积断裂下部对油气的横向封堵性要明显强于上部;断裂活动早中期对油气的输导性要强于晚期及断裂活动停滞期。精细刻画盆地内部断裂带内部结构特征对于分析断裂在油气运聚中所起的作用具有重要意义。

| Abstract: | Fault zone is a complex three-dimensional geological body with heterogeneous structures which can be divided into unit types with different properties, such as low-permeability slip damage zone and high-permeability induced fracture zone and so on. Controlled by various geological conditions and factors, internal structures of fault zone in different kinds and activity intensity faults, hanging wall and footwall, different depth of growth fault are different, which make faults having dual nature and temporal and spatial differences in transporting and sealing oil and gas: induced fracture zone can be the channel of transporting oil and gas, but slip damage zone has a strong horizontal segregation; Oil and gas horizontal sealing of the lower part of growth fault is obviously stronger than the upper; Oil and gas transporting capacity of fault in early and middle fault activity is stronger than in late and resting stage. Meticulous depiction of internal structure of fault zone inside basin is great significant in analysis the role of fault in the oil and gas migration and accumulation. |
