摘要

以东营凹陷永95井为例,根据岩心、测井、地震等资料,从地震相和单井相两方面对永95井冲积扇特征进行了剖析。其中,根据单井相分析将该井冲积扇沉积相分为扇根、扇中、扇端3个亚相,并将扇中亚相细分为辫状水道、辫状水道间和纵坝3个微相。勘探表明,冲积扇沉积易形成有效储层,形成油藏还具有"自我保护"的能力;冲积扇的形成很可能使上覆地层形成扇背斜油藏,或使下伏基岩形成基岩风化壳油藏。
The characteristics of alluvial fan in Well Yong 95 are studied in respects of seismic facies and single well facies according to core, logging and seismic data. The alluvial fan facies in this well is divided into 3 subfacies of root-fan, mid-fan and end-fan based on single well facies analysis, of which the mid-fan subfacies is subdivided into 3 microfacies of braided channel, inter-braided channel and vertical-bar. It has been proved by exploration that alluvial fan deposition tends to form effective reservoirs which have self-protection ability; an alluvial fan is likely to have fan-anticline reservoirs in its overlying formation or weathered crust reservoirs in underlying basement.
