摘要
焉耆盆地侏罗系具近物源沉积特点 ,储层成分成熟度和结构成熟度均较低 ,粘土矿物含量高 ,物性较差 ,属低渗透储层。“五敏”实验结果表明 ,储层均表现为强水敏特征 ,物性相对较好的储层还表现出强盐敏和中等偏弱速敏、碱敏等敏感性特征 ,盐酸对储层具有一定程度的改善 ,并进一步探讨钻探施工过程中油层保护的措施及应用效果。
Jurassic in Yanqi Basin was characterized by closing to sediment source low permeability reservoir,low compositional maturity and structural maturity,high content of clay mineral and poor physical property. The sensitivity test showed that reservoir was of strong warter sensitivity.Reservoir of good reservoir protection showed the characteristics of strong salt sensitivity,middle to weak speed sensitivity and alkali sensitivity.Hydrochloric improved reservoir to some extent.This paper also discussed the reservoir protection and application effect in drilling.
