摘要
传递斜坡是调节区域构造应变平衡的一类重要的构造样式。根据新的三维地震资料解释和断层位移-距离关系以及相干体切片分析,探讨了渤海湾盆地辽西低凸起传递斜坡的特征,并简要分析传递斜坡与潜山油气聚集的关系。地震剖面解释表明,辽西低凸起潜山带的传递斜坡连接辽西1号断层的下盘和辽西2号断层的上盘;在数据体相干切片上,辽西1号和2号断层呈清晰的侧接形态;而位移-距离关系显示,辽西1号断层的位移沿着断层走向自南向北逐渐传递到辽西2号断层,断层位移在传递斜坡内部基本保持守恒。传递斜坡对潜山油气聚集的意义主要表现在对储层形成和改造方面,优质储层发育是JZ25-1S潜山大油气田的重要成藏要素。
Relay ramp is an important structural style to accommodate regional strain balance.According to new 3-D seismic data interpretation,fault displacement-distance relation and seismic coherence slice analysis,this paper discussed some features of the relay ramp in Liaoxi low-uplift,Bohai bay basin,and briefly analyzed the relationship between relay ramp and hydrocarbon accumulation of buried-hill reservoir.The seismic profile interpretation indicates that the relay ramp of buried-hill belt in Liaoxi low-uplift connects footwall of Liaoxi No.1 fault and hangingwall of Liaoxi No.2 fault.On the seismic coherence slices,lateral connection with Liaoxi No.1 fault and Liaoxi No.2 fault is very clear.However,according to the fault displacement-distance relation,Liaoxi No.1 fault displacement is gradually transferred to Liaoxi No.2 fault along the faults strike.At the same time,this displacement is fundamental to maintain conservation in relay ramp.The relay ramp's significance for hydrocarbon accumulation is mainly exhibited in the formation and transformation of buried-hill reservoir.High quality reservoir is the material base of JZ25-1S buried-hill hydrocarbon reservoir.
