QHD33-1南油田是一个已勘探发现但尚未动用的稠油油田,跟以往稠油油田开发不同,油田立足于以热采开发方式为主的前期开发,热采开发方案设计需要大量的室内实验数据。基于室内物理模拟,采用高温高压实验仪器,开展了多种非凝析气对稠油高温高压热物性影响的研究。结果表明,QHD33-1南油田稠油在相同温度和压力下溶解CO2与油体积比明显高于N2,溶解CO2的降黏率可达30%~90%,温度越低,压力越大,溶解CO2的降黏作用越明显；在实验温度和压力下溶解 N2降黏幅度均低于20%；烟道气的溶解能力及降黏效果高于 N2,低于CO2。

The southern part of Qinhuangdao 33-1 oil field is a heavy oil field which has not been exploited.The mode of thermal recovery is considered unusually in the early of exploitation.The design of thermal recovery mode depends on mass experimental data.Based on the indoor physical simulation,the influence of different non-condensate gas on high temperature and high pressure property of heavy oil is studied with a set of experiment instrument which support high temperature and high pressure.The results show that the volume ratio of CO2 dissolved in heavy oil of the southern part of Qinhuangdao 33-1 oil field is higher than N2 obviously,and the reduction rate of CO2 is 30%~90%.The lower temperature and greater pressure make CO2 reduce the viscosity of heavy oil more effectively.In different experiment temperature and pressure conditions,the N2 viscosity reducing extent is lower than 20%,and the dissolving capacity and viscosity reducing effect of flue gas is between N2 and CO2 .
