| 摘 要： | 主要讨论了正断层软联接及其传递带的类型、正断层软联接的运动学特征及其传递带形成和油气勘探意义。通过上述分析,获得以下结论:根据正断层倾向及其叠覆段的组合特点,可将软联接正断层分为同向叠覆、对向叠覆和背向叠覆3种类型,与之对应的传递带类型分别为走向斜坡、斜向背斜和地垒;软联接的正断层之间由于断层位移变化引起的断块变形体称为传递带;准确认识软联接正断层的剖面和平面特征是提供可靠地震解释模型的保证,软联接正断层及其传递带控制着沉积体系和油气分布。

| Abstract: | The paper mainly discussed the types of normal faults' soft linkage and the corresponding transfer zones,the kinematic characteristics of the normal faults' soft linkage,the formation of transfer zones and the significance of the normal faults' soft linkage and corresponding transfer zones in petroleum prospecting.From(above) discussions,it is concluded that:(1)according to the assembling characteristics of the dip direction of normal faults and their overlap zones,normal faults' soft linkage can be classified into synthetic overlap,convergent conjugate overlap,divergent conjugate overlap,and corresponding transfer zones are relay ramps,oblique anticlines and horsts,respectively;(2) the normal faults of soft linkage usually have different displacements,and thus cause the metamorphose of faulted blocks.The plasmodia of faulted blocks are called transfer zones;(3) accurately cognizing the profile and planar features of normal faults of soft linkage is the base of reliable seismic interpretation models,normal faults of soft linkage and corresponding transfer zones have apparent control over the depositional system and the distribution of petroleum. |
