为了对斯坦福大学地震层析成象研究组在McElroy油田进行的一系列井中野外实验提供支持数据,我们完成了一项岩芯分析工作。本次工作的目的是证明井间地震剖面能用于确定储层特征并对注入的CO_2气进行监控。对西德克萨斯碳酸盐岩,我们估算出CO_2气饱和后P波速度的变化为—1.9％(合并平均值的范围为—6.3～+0.1％),S波速度的变化为+0.6％(范围由0～2.7％),P-S速度比的变化 In support of a series of well field field experiments conducted by the Seismic Tomography Research Group at the McElroy Field at Stanford University, we completed a core analysis. The purpose of this work is to demonstrate that crosswell seismic profiles can be used to determine reservoir characteristics and monitor the injected CO 2 gas. For the West Texas Carbonate, we estimate a -1.9% change in P-wave velocity after CO 2 gas saturation (the combined mean ranged from -6.3 to + 0.1%) and a S-wave velocity change of +0.6 % (Range from 0 to 2.7%), PS speed ratio changes
