摘　　要：CO_2气临界温度较低,接近常温,受温度、压力影响CO_2在井下可呈气相、液相。通过实验室样品模拟物理参数试验及对井下温度、压力和压力梯度测量,分析CO_2在井下的相态特征。Critical temperature of CO_2 gas is much low which is close to normal temperature. It is assumed gas or liquid phase influenced by T & P. Through the experiment of simulating physical parameter for lab sample and measuring down hole temperature, pressure and pres- sure gradient, phase characteristics of CO_2 gas well at down hole is analyzed.
