摘　　要：牙哈凝析气田是目前国内已投入开发的规模最大的,具有边水的整装凝析气田。对于水侵凝析气藏,掌握了水侵特征才能有效改善气藏的开发条件。在现场应用中经常采用试井解释的方法研究边水推进的情况。但井底相态变化会影响到试井特征曲线,从而使边水推进的情况不易判断。文章使用现代试井解释方法,应用KAPPA公司的Saphir试井解释软件对牙哈凝析气田3口生产井历次压力恢复试井先进行了试井解释,然后建立三维数值模型,将试井解释成果与数值模拟研究成果相结合,综合判定牙哈凝析气田边水推进的情况。这对正确认识凝析气藏开发动态及水侵特征,加强动态监测技术研究,对凝析气藏进行有效开发起着重要的指导作用。Yaha condensate gas reservoir is the biggest gas reservoir with edge water,which has been explored in China.In order to improve the development conditions of gas reservoir with edge water,the characters of water incursion must be known.The well test interpretation was usually used in research of edge water incursion,but the change of bottom phase state would impact the characteristic curve of well test,the edge water incursion wouldn't be judged accurately.The well test interpretations of 3 wells in aha condensate gas reservoir were carried out and the 3D numerical model was established by using modern well test method,and the Saphir well test interpretation software of KAPPA Co.Combined with the results of well test interpretation and numerical simulation,the status of edge water incursion of Yaha condensate gas reservoir was judged.These would play an important role on understanding the gas field development performance and enhancing the research on dynamic detection technology.
