摘　　要：针对盆五井区底水油环凝析气藏的地质特征,应用地质建模软件建立构造模型、储层模型,展现出底水油环凝析气藏的构造和储层特点。在此基础上,应用CMG数模软件描述了剩余油分布特征,讨论了底水油环凝析气藏剩余油的分布特征,认为剩余油主要分布在井网系统局部不完善区、储层物性不利区、未达到经济极限生产条件的储量损失区。根据剩余油气分布的特点,进行了治理方案部署,经实施后取得了良好效果,平均年增油1.49×104t,年综合递减减缓1.6%,实现了油气高效开采。According to the geologic characteristics of bottom-water and oil-ring condensate gas reservoir in Penwu wellblock, the structural and reservoir models have been established by geologic modeling software to present the structural and reservoir characteristics. On this basis, residual oil distribution features are described by CMG mathematical modeling software, and the features of bottom-water and oil-ring condensate gas reservoir are discussed. The result shows that residual oil mainly distributes in areas with partially faulty well pattern system, unfavorable reservoir physical properties, and reserves loss failing to reach the limit of economic producing condition. Based on the distribution, a treatment has been implemented with a good result. An increase of average oil increase is 1.49×104t/a, a decreasing rate slows down 1.6%/a. Recovery with a high efficiency has been realized.
