摘要:
雅克拉、大涝坝等凝析气藏属中小型边底水碎屑岩凝析气藏,具有埋藏深、凝析油含量高、储层敏感性强、非均质性强、隔层 厚度大、中低渗等特点。1984年投入试采,2005年全面投入开发,在凝析气藏开采工艺方面积累了大量的经验,特别是在凝析气 藏射孔完井方面经过多年的优化应用,形成了一套适用于各气藏不同储层特征、不同开发阶段的射孔完井工艺技术体系,提高了 凝析气藏开发效果。
Abstract:The gas condensate reservoirs in Yakela and Dalaoba regions are middle and small sized clastic rock reservoirs with edge and bottom water, characterized by deep burial depth, high condensate oil content, strong reservoir sensibility, strong heterogeneity, big barrier thickness and medium-low permeability. Production tests were made in 1984 and fully developments were carried out in 2005, resulting in experiences in condensate oil exploration. Perforating technology has been practiced and improved for years. A set of perforating technology system suitable for different reservoir characteristics and exploration stages was proposed, improving gas condensate reservoir exploration effects.
