摘　　要：二氧化碳(CO2)流体密度在地层温压条件下的变化规律,对定量计算气层CO2含量具有理论指导作用。借鉴他人的试验数据,探索研究得到地层温压条件下CO2流体体积密度数学模型,通过密度测井响应方程将CO2体积密度转为密度测井响应值,从而为定量计算气层CO2含量提供了可靠的依据。研究结果表明,所得的CO2密度测井响应值模型是可靠的,可以作为测井评价参数使用。The laws of CO2 density changes in the pressure and temperature conditions could provide a theoretical guidance for a quantitative calculation of CO2 content in gas zone. By using experimental data from predecessors and a mathematical model of CO2 density was studied in the formation conditions, the CO2 density can be turned into the logging density through the density logging response equation, thus to provide a reliable basis to quantitative calculation of gas CO2 content. The results show that the computing CO2 density logging is reliable and can be used as a logging evaluation parameter.
