摘要
储层敏感性指对储层造成伤害的各种因素的敏感程度。储层敏感性分析的主要目的是研究各种敏感因素对储层的伤害程度,并提出预防措施,提高原油的最终采收率。为了研究银根-额济纳旗盆地巴北凹陷二叠系储层在开采过程中对储层的伤害,对其岩心做了大量的室内实验研究,并利用储层敏感性实验评价方法,参照储层评价标准对该区敏感程度进行了评价。结果表明,二叠系埋汗哈达组储层具有中等偏强酸敏、弱碱敏、中等偏强盐敏、中等偏强水敏及中等偏弱速敏。在将来的勘探开发中,保护油气层、增产措施的选择可采用相应的应对措施。
Reservoir sensitivity is the degree of sensitivity to various factors that cause damage to the reservoir.The main purpose of reservoir susceptibility analysis is to study the damage degree of various sensitive factors to reservoirs and to propose preventive measures to improve the final recovery rate of crude oil.In order to study the damage to the reservoirs in the Permian reservoirs in the Babei depression of the Yingen-Ejinaqi basin,the authors carried out a large number of laboratory experiments on the core of the reservoir.The reservoir sensitivity test was used to evaluate the reservoir sensitivity.The standard was evaluated for the sensitivity of the area.The results show that the reservoirs of the Permian buried Khan Formation are intermediately strong,sensitive,weakly alkaline,moderate to strong,and slightly weak and medium weak.In the future exploration and development,the protection of oil and gas as well as the increase in the choice of measures can be used to respond to the corresponding measures.
