| 摘 要： | 针对鄂尔多斯盆地东部上古生界气藏选取24块样品开展敏感性实验。研究表明储层具有常温低压低孔低渗的特点,储层应力敏感性和水锁效应强是储层伤害的主要形式,其原因在于储层平均孔喉半径细小,微裂缝较发育,喉道类型以片状喉道为主。在速敏、水敏、盐敏、酸敏、碱敏实验分析基础上研究认为研究区储层敏感性总体表现为弱敏感性。

| Abstract: | This paper focuses on the sensitivity experiment of 24 sandstone reservoir samples in east Ordos Basin which is characterized by modern temperature,low porosity,low pressure and low permeability. The research shows that formation damage consists of extensive sensitivity and water blocking. And the micro average pore throat radius,common fracture, laminated structure throat channel jointly lead to formation damage. Based on the experiment data analysis of velocity sensitivity, water sensitivity,acid sensitivity,salt sensitivity and alkali sensitivity,weak reservoir alkali sensitivity is embodied in majority of reservoir,and strong alkali sensitivity in minority of reservoir. |
