摘要： 克拉玛依油田五东区上乌尔禾组油藏 $P_{2}w^{2}_{3}$ 砂层为主力油层,纵向非均质性较强,主要发育 3 套碎屑岩储集层。由于储集层岩性及胶结程度的影响,主力油层取心井段岩心难以钻切成形,开发至今一直缺少室内动态敏感性实验资料。采用多种物模,对不同胶结类型和胶结程度的砂砾岩段进行了敏感性特征评价,并从储集层中粘土矿物类型、产状、相对含量以及储集层孔喉的发育特征等方面进行了敏感性伤害机理分析,为现场制定开发方案和调整措施提供了相关的理论依据。

Abstract: The $P_{2}w^{2}_{3}$ sand layer of Upper Wuerhe reservoir in East District No.5 in Karamay field is the major oil reservoir with serious vertical heterogeneity and composed of 3 sets of clastic reservoirs. Because of the influences of reservoir lithology and cementation, it is hard to take shaped cores from the coring section in the major reservoir, and lacks the lab-analysis data of their dynamic sensitivities. In this paper, the sensitivity characteristics of glutenite sections with different cementation types and degrees are analyzed using several kinds of physical models, including the sensitivity-damage mechanism analysis from many aspects such as type, occurrence and relative content of clay minerals as well as development features of pore throat in these reservoirs. This study provides relevant theoretical basis for modification of field development plans and measures.

Key words: Karamay field, Upper Wuerhe formation, heterogeneity, cementation type, latent sensitivity, dynamic sensitivity, damage mechanism
