【摘要】 老河口油田是在平缓单斜背景上发育的典型的隐蔽性岩性油藏。文中针对该区地层平、断层少的地质特征,以高品质地震资料为基础,利用小波域信号重构处理方法,对等时地层单元内河流相储层的岩石物理学特征和储层正演模型特征进行了分析。结合水平切片技术和三维可视化技术对砂体进行了追踪解释,并根据砂体吸收系数的特征,利用叠后信息进行油气判识,总结出一套针对馆陶组岩性油藏描述的方法。更多还原

【Abstract】 The Laohekou Oilfield is a type of subtle lithologic reservoir found at a single gentle anticline, where the strata are flat and the fault is few. Based on high quality of seismic data, the method of signal reconfiguration in wavelet domain is used to analyze the petrophysics and forward model characteristics of fluvial facies reservoir in isochronous stratigraphic framework. The time slice technique and 3D visualization technique are applied to carry out sand body trace and interpretation. According to absorption coefficient features of sand body, the post-stack seismic data are used to conduct oil and gas identification. A set of methods for lithologic reservoir description of Guantao Formation is concluded.更多还原
