摘要/Abstract

摘要： 为进一步提高盐水层中CO₂埋存潜力评价的准确性,基于物质平衡方法,建立CO₂构造埋存过程的物质平衡方程,在对CO₂可埋存地下体积准确计算的基础上,提出了一种新的CO₂理论构造埋存量计算方法。结果表明:新方法计算的CO₂理论构造埋存量,与面积法、容积法相比,误差更小,仅约为10%;新方法可同时预测CO₂增压埋存条件下和保压埋存条件下的理论构造埋存量,且随着注入时间或注采比的增加,CO₂理论构造埋存量和地层压力均呈现不断增加的趋势。该方法对CO₂构造埋存量研究及CO₂注入量实时动态控制具有重要意义。

Abstract: To further improve the evaluation accuracy of CO₂ storage potential in saline layer, a new method for calculating the theoretical tectonic CO₂ storage volume was proposed based on the material balance equation of CO₂ tectonic storage process and the accurate calculation of underground volume of CO₂ storage. As found in the results, the error of theoretical tectonic CO₂ storage volume calculated by the new method was smaller than that of area method and volume method, which was only about 10%; the new method can predict the theoretical tectonic storage volume under both CO₂ pressurized and pressure-retaining underground storage conditions; both theoretical tectonic CO₂ storage volume and formation pressure showed a trend of increasing with the increase of injection time or injection-production ratio. The new method is of great significance to the study of CO₂ tectonic storage and real-time dynamic control.

Key words: tectonic CO₂ storage, saline formation, theoretical tectonic storage, material balance
