摘要
通过对油田河道砂岩厚油层内部夹层的分布状况及河流相沉积环境中夹层的成因分析,结合油田目前夹层识别的技术现状,将河道砂岩厚油层内部夹层划分为单元间及单元内两大类。通过单砂体到单一点坝再到砂体内部夹层的描述思路,实现了侧积夹层的三维数字化表征,建立了水平状夹层三维地质模型,在储层深层次描述方面取得突破性进展。分别描述了它们的分布特征及其在油田开发中的作用,指出了夹层研究的主攻方向。
Based on the analysis of the distribution of interlayer in thick channel sand oil reservoir and the origin of interlayer in fluvial depositional environment, associating with present technique of identifying the interlayer in oilfield, the interlayer in thick channel sand oil reservoir is divided into 2 categories： that in units and that between units. According to the idea describing from mono sandbody to single point bar and then interlayer in sand body, 3D digital simulation of lateral accretion interlayer is established. Great advancement in reservoir description has been achieved. The distribution characteristics of interlayer and its role in oilfield development are discussed, and the further research concerned interlayer is put forward.
