摘要
缝洞型碳酸盐岩凝析气藏储层结构、流体性质复杂,造成其流动机理及凝析油反蒸发机理不同于砂岩凝析气藏,需要进行开发机理研究来为缝洞型碳酸盐岩凝析气藏提高采收率提供理论基础。本文取得塔中Ⅰ号碳酸盐岩凝析气田露头岩心造缝造洞,采用现场取得的油气样进行配制,使用高温高压全直径岩心设备进行了垂直衰竭、水平衰竭、注干气保持压力、注水保持压力、注干气吞吐、注水替凝析油的全直径岩心物理实验研究。实验根据缝洞型储层不同结构特征分类对比了各种开发方式对凝析油采收率的影响,对缝洞型储层高含凝析油型凝析气藏的合理开发具有很好的指导意义。
Fractured-vuggy carbonate gas condensate reservoir's structure and fluid property are complex,which causes its flow mechanisms and the mechanism of condensate oil evaporation different from the gas condensate sandstone reservoir,so development mechanism to improve oil recovery rate needs studying.Outcrop core of Tazhong1 are made sewing and hole,the samples are made by oil and gas from the scene,then using the diameter of the core equipment with high temperature and high pressure,the diameter core physical experiment research are carried out.Condensate oil recovery rate of various development way are compared based on different structure characteristics of fractured-vuggy reservoir.For the rational development of Fractured-vuggy carbonate gas condensate reservoir,this has the significant guidance.
