摘要: 文章针对放一断块气井多层合采提高单井配产产量,应用数值模拟技术研究提高采气速度的最佳开发方案,使现有6口生产井配产提高至日产180×104m3凝析气,采气速度由原方案设计的4.6%提高至7%,数值模拟计算8种不同配产方案的技术指标预测,优化推荐最佳方案。研究预测提高气井产量至日产凝析气180×104m3,可稳产6年,相应地天然气采出程度为50%、凝析油采出程度为38%。Abstract: The gas wells in F1 block, Pinghu oil &gas field are commingled producing wells.In order to enlarge gas rate, numerical simulation research was applied to get optimum result s.8 development plans were computed and the best one was recommended for field operation.The result shows that 1.8×106m3/d gas rate is feasible by increasing the existing 6 production wells' capacity.The yearly off-take rate will be adjusted from 4.6% to 7% and the gas plateau time will be 6 years.The corresponding recovery percent of natural gas and condensate oil is 50% and 38% respectively at the end of gas plateau.
