| 摘 要： | 凝析气藏凝析气衰竭测试通常在PVT筒中进行，没有考虑多孔介质的影响，而实际储层中流体相态的变化却是在多孔介质中发生的。通过长岩芯实验研究了凝析油气体系在多孔介质中的衰竭动态，并与PVT筒中的衰竭进行了对比。研究发现：长岩芯中富含凝析油型的凝析气衰竭动态与PVT筒的测试结果存在一定差异，不同衰竭速度所得各级压力下平均气油比不同，速度越大，平均气油比越大，凝析油采收率越低；长岩芯中凝析油采收率高于PVT筒中采收率，天然气采收率则相差不大。因此，应尽可能采用岩芯衰竭实验研究凝析气藏衰竭开发反凝析动态特征。

| Abstract: | The depletion test for the condensate gas in gas condensate reservoir is usually done in PVT cell without considering the influence of porous media，but in real reservoir，the change of fluid phase behavior occurs in porous media.By means of long core test，the depletion performance of condensate gas system in porous media is studied，and the comparison with the depletion in PVT cell is carried out.Study indicates that the condensate gas rich in oil condensate depletion performance is different with PVT test result，average oil-gas ratio is different under different pressure in different depletion speed，the higher the speed is，the lower the recovery of oil condensate is，and the greater the average oil-gas ratio.The oil condensate recovery in long core is higher than that in PVT cell，but there is only a little difference for natural gas recovery.It is strongly suggested that core depletion test is used to study retrograde condensation performance feature in gas condensate reservoir depletion production. |
