摘　　要：以胜利油田正在实施CO2驱的某区块为研究对象,通过室内模拟试验模拟地质封存CO2泄露,考察CO2泄露对土壤金属的影响,探讨土壤金属状态变化的机理。研究结果表明,地质封存CO2的泄露会对土壤金属含量产生显著影响,随着CO2泄露浓度的增大,土壤Ca+、Mg+含量降低,Fe+、Mn+、Zn+、Cu+含量增多,K+、Na+、Pb+、Cr+基本不变。In order to study the influence on the metal of soil for CO2 leakage and explore the state changes of soil metal, we research a certain area implemented CO2-driven by SLOF（shengli Oil Field） by means of indoor simulation experiment which simulate the leakage of Carbon dioxide. It was found that it had the greatest impact on the metal content of soil. With the increase of concentration of CO2 leakage, the content of Ca^＋、Mg^＋ was reduced, the content of Fe^＋、Mn^＋、Zn^＋、Cu^＋ was increased, the content of K^＋、Na^＋、Pb^＋、Cr^＋ was unchanged.
