摘　　要：扬古伊气田位于土库曼斯坦阿姆河右岸B区块中部,是阿姆河天然气公司第二处理厂的主供气田之一。气田主体构造扬古伊圈闭计算天然气地质储量达数百亿立方米,斜坡带及其上部局部小圈闭的估算天然气资源量也十分可观。针对该气田J3k-o气藏属超高压湿气气藏、受构造和岩性控制、储层纵横向上非均质性及应力敏感性较强等特点,提出了高效开发的策略:①衰竭式开采;②非均匀方式布井;③采用大角度斜井井型;④分批部署、滚动实施;⑤气藏投入开发后要尽量减少开关井次数。这对于控制井底流压,保持合理的地层压力,减小储层伤害并及时进行产能测试评价、合理配产,获得较好的开发效果发挥了重要作用。The Yangguyi Gas Field is located at the central section of the Block B at the right bank of the Amu Darya River in Turkmenistan,which is one of the main gas resources of the second Gas Processing Plant of Amu Darya River Natural Gas Company.The gas-in-place in the Yangguyi trap,the main structure of this gas field,is estimated to be about several ten billion cubic meters,and the predicted gas-in-place in the slope zones and its top small traps is also considerable.Aiming at the characteristics of this ultra-high pressured wet gas reservoir with great heterogeneity and strong stress sensitivity,which is controlled by structure and lithology,strategies for the high-efficiency development of the J3k-o gas reservoir,in this field are proposed including depletion development,uneven well pattern,high angle deviated wells,deployment and implement in turn,cutting down the open-shut times after this gas reservoir is put into production.These effective strategies not only help control the bottomhole flow pressure,keep the rational formation pressure,and decrease the damage to the reservoirs,but also play an important role in the deliverability test,rational proration,and better development achievement.
