通过对塔南凹陷断裂特征分析的基础上划分断裂系统,分析断裂系统对油运聚成藏的控制作用。共发育4类断裂系统:Ⅰ型(早期伸展断裂系统)、Ⅱ型(中期张扭断裂系统)、Ⅰ-Ⅱ型(早期伸展中期张扭断裂系统)、Ⅰ-Ⅱ-Ⅲ型(早期伸展中期张扭晚期反转断裂系统)。控圈断裂系统为Ⅰ型、Ⅱ型和Ⅰ-Ⅱ型。Ⅰ型和Ⅰ-Ⅱ型断裂系统主要起侧向遮挡作用;Ⅰ-Ⅱ-Ⅲ型断裂系统控制着大磨拐河组油藏的分布。
Based on the analysis of fault characteristics in Tannan Sag, the fault system is divided into two parts to analyze the controlling effect of fault system on the hydrocarbon accumulation. Four types of faulting systems were developed: type Ⅰ (early extensional rupture system), type Ⅱ (medium-term tensile torsional rupture system), type Ⅰ-Ⅱ (early extensional midshare torsional rupture system), type Ⅰ-Ⅱ-Ⅲ Zhang reverse late rupture system). Control ring fracture system for type Ⅰ, Ⅱ and Ⅰ-Ⅱ type. Type I and type I-II fracture systems mainly act as lateral occlusions; Type I-II-III fracture systems control the distribution of the Damoguaihe Formation reservoir.
