一种碳酸盐岩储层中流体替换的实现方法
Keywords: 岩石物理,流体替换,gassmman方程,碳酸盐岩储层
Abstract:
？在进行碳酸盐岩储层及含油气性地震预测时,需要对碳酸盐岩储层充填不同流体后岩石物理性质的变化有清楚的了解。为此,在缺少岩石物理测试资料的情况下,需进行流体替换研究。本文给出了一种在碳酸盐岩储层中进行流体替换的实现方法。该方法利用全波测井资料求取碳酸盐岩岩石基质的弹性参数,以batzle等人的经验公式计算流体的弹性参数,应用gassmman方程完成岩石骨架弹性参数的计算和流体替换。该方法的特点在于用统计平均的方法求出岩石基质的弹性参数,因而不需要岩石矿物组分等数据,在实际应用中更为方便。
