【摘要】 准噶尔盆地乌夏断裂带乌尔禾地区二叠系夏子街组发育着一大套厚层砾岩体,砾岩体的顶部含有高产油层,但在地震剖面上这套砾岩体与下部地层的反射差异并不明显,给砾岩体的识别和追踪带来了困难。用频率属性分析技术对其进行了深入的研究,揭示了它与下部地层的反射区别,通过对三维地震数据体进行处理,确定出这套砾岩体的标志并圈定了平面分布范围。研究结果与井资料的吻合程度较高。更多还原

【Abstract】 There exists a set of thick conglomerate body in Xiazijie formation of Permian in Wuerhe area in Wu-Xia fault belt, and high-yield oil zone was found at the top of it. However, it is not obvious differences in seismic reflection between the conglomerate and underlying strata, which allow the identification and tracing to be difficult. This paper presents in-depth research on that by frequency attribute analysis and finds out the reflected differences. By 3D seismic data process, the conglomerate feature is confirmed, and its plane distribution is outlined. The results show a coincidence with the well data.更多还原
