摘要

通过岩心观察确定岩石类型、岩相类型,结合地震相、测井相分析,对扶Ⅰ油层沉积微相进行了系统研究。结果表明:该油层为冲积-河流相沉积,主要发育曲流河道,决口河道,决口扇,冲积平原及开阔浅水湖泊边缘5个微相。在此基础上,根据岩心微相分析、小层砂体形态和测井剖面对比及井间横向对比,研究了扶Ⅰ1、扶Ⅰ2、扶Ⅰ33个小层的沉积微相平面展布特征及其变化规律,为油田开发方案的调整和动态分析提供了可靠的地质依据。
The methods of analyzing the log facies and observing cores were used to acquire the types of the rocks, the types of lithofacies, and the features of combination facies,the sedimentary microfacies , FuⅠoil layer was systematically studied. The result showed that reservoir belonged to alluvial- fluvial facies deposit, and it was further divided into 5 microfacies, including meander channels, crevasse channels, crevasse fans, alluvial plains and shallow lakes. According to the microfacies of cores, the shape of the sand body and the comparison between the logging profiles, the evolution and distribution of the microfacies in the FⅠ1,FⅠ2,FⅠ3 substrata were studied. The results can provide a geological foundation for the adjustment of reservoir development scheme and dynamic analysis.
