摘要：
利用自行研制的高温高压反应釜,在不同温度、压力和矿化度条件下测试CO2在地层水中的溶解度。实验结果表明:温度一定的条件下,CO2在水中的溶解度随压力的增加而增加;压力一定的条件下,CO2在水中溶解度的主要变化趋势为随温度的增加而降低,当温度大于100℃、压力在22 MPa左右时,CO2在地层水中的溶解度将发生异常,出现低压(小于22 MPa)时随温度的增加而降低,高压(大于22 MPa)时随温度的增加而略微升高;在温度压力都一定的条件下,CO2在水中的溶解度随矿化度的增加而降低。并且,在新测得的实验数据和已有的实验数据的基础上,通过修正PR-HV状态方程中的参数,建立了一个能够精确计算CO2在水中溶解度的模型;并将该模型与其他模型对比。对比结果表明,该模型计算精度最高,平均相对误差仅为2.69%。
