摘要
为了分析济阳坳陷沙河街组河道与浊积扇砂体、泥灰岩、冲积扇体、滩坝砂体等沉积体的地震相特征,利用沉积成因、岩性组合和地震反射特征综合分析方法,划分出了4种地震相类型,明确了地震相特征。进一步分析了不同沉积体储层地震描述难点,提出了储层预测技术对策,为油气勘探的储层精细描述研究提供了一种新的思路和方法。
To analyze the seismic facies characteristics of river channels,turbidite fan sand bodies,marl limestones,alluvial fan bodies,and beach bar sand bodies in the Shahejie Formation of Jiyang Depression,a comprehensive analysis method based on sedimentary genesis,lithological assemblage,and seismic reflection characteristics was used to identify four types of seismic facies.The characteristics of these seismic facies were clearly defined.Further analysis of the seismic description difficulties of different sedimentary bodies was conducted,and technical countermeasures for reservoir prediction were proposed.This offers a new approach and method for the fine description of reservoirs in oil and gas exploration.
