中文摘要：

为了解决花岗岩潜山储层内部结构复杂、非均质性强、在数值模拟建模过程中模型参数填充误差大的问题,本文提出了一种基于地震属性建模的数值模拟技术。该技术首先优选地震属性建立储层模型;然后采用波动方程的数值模拟方法对模型进行“正演＋偏移”计算,并对比分析模拟得到的偏移剖面与原始地震剖面,逐步修正观测系统参数,直至两者的主要特征一致;最后,结合其他地震属性（如裂缝检测属性）,综合分析目的层的地震响应特征。对渤海某区花岗岩储层的数值模拟结果表明,该方法有效地刻画了花岗岩“溶蚀孔隙＋高角度裂缝”所形成的“串珠状”反射特征,为该区后续的勘探研究奠定了基础。利用本文提出的方法综合分析储层结构的地震波场特征是一种可行的方法,该方法除了应用于花岗岩储层的数值模拟外,还可以应用于其他复杂储层的数值模拟。

英文摘要：

A num erical sim ulation m ethod based on m odeling constrained by seism ic attribution isproposed to cope w ith the com plex structu re, strong heterogeneity and inhom ogeneity in explorationof granite buried hill reservoirs. F irstly , reservoir model is established by selecting preferred seismicattribution follow ed by sim ulation by wave equation to get a satisfied re su lt; then, the sim ulated crosssection and original cross section are correlated and the observation param eters are revised until them ajor characteristics of the tw o cross sections reach unanim ous. T he num erical sim ulation on granitereservoir in Bohai area indicates that this m ethod can efficiently describe “ the string of beads-like”reflection characteristics caused by high angle fractures and corroded fissures in granite, which is veryim portant to subsequent exploration of oil and gas. T he num erical sim ulation m ethod can apply to granite, reservoirs and other com plex reservoirs.
