摘　　要：运用定容衰竭实验和注平衡气驱渗流机理的组合长岩心实验方法,对ZYBM-BP2凝析气气藏井流物组分进行分析,测定和计算不同压力地层流体露点,评价衰竭平衡气长岩心注气驱开发效果,分析开发过程中的渗流规律。研究结果表明,实验渗流特征研究成果可用于指导凝析气藏现场开发。Utilizing the constant volume depletion experiments and the experimental method of combined long-cores by injecting balance-gas,the composition of well flow material was analyzed in ZYBP-2 condensate gas-reservoir,the dew points of formation fluid under various pressure were measured and calculated,the depletion development effects of long-cores by injecting balance-gas were evaluated,and the infiltration flow rule in the development was analyzed.The results showed that the infiltration flow characteristics can provide guidance for development of condensate reservoir.
