摘要：
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.
