几种常见震积岩相标志在模拟实验中的识别
|
摘要
震积岩相标志是识别震积岩的最有效依据。在对震浊积岩形成过程的水槽模拟实验中,发现了同沉积断裂、微褶皱纹理、液化砂岩脉、液化均一层、同沉积变形构造、震浊积岩等典型的软沉积物震积岩相标志,他们形成于地震作用的不同阶段,有规律的分布在三角洲—震浊积岩体系之中。同时,模拟实验中也发现了一些与震积岩相标志易混淆的其他成因相标志,因此在分析过程中应该充分考虑各种相标志的组合特征、与沉积环境的配置关系以及区域的构造背景等。依据模拟实验得出的震积岩相标志分布模式,通过相标志类型和组合特征分析,可进行震浊积体发育区带预测,指导断陷盆地隐蔽油气藏勘探。
Sedimentary facies indicators are the best effective criteria to identify seismites.In the flume experiments to simulate seismo-turbidites,several typical facies indicators of seismites are found in soft sediments,such as synsedimentary faulting,microcorrugation,liquefied sandstone dike,liquefied uniform bed,syndepositional deformation,seismo-turbidites,and so on.They formed in different periods of seismism and distribute regularly in the system of delta to seismo-turbidites.At the same time,some facies indicators induced by other contributing factors are discovered,which is confused with facies indicators of seismites.So when analyzing seismites we should also consider the assemble characteristics of all kinds of facies indicators,their allocation relationship with depositional environment and regional tectonic setting.The distribution pattern of facies indicators of seismites can be derived from simulated experiments.According to analyzing the types and assemble characteristics of facies indicators of seismites,we can forecast the best zones that develop seismo-turbidites and guide subtle reservoir exploration in faulted basin.
