摘　　要：以钻井、岩心、录井、测井、测试分析资料为基础,系统总结了面古3井古潜山岩溶储层特征,指出面古3井古潜山风化壳岩溶储层发育,纵向可分为垂直渗流带、水平潜流带和深部缓流带。其中垂直渗流带岩溶作用强,但充填作用亦较强,储集性能较好;水平潜流带溶蚀作用强烈,充填作用较弱,岩溶储层储集性能最优;深部缓流带岩溶作用比较微弱,储集性能较差。The characteristics of karst reservoirs of paleo--buried hill weathering crust in Well Miangu 3 in Bamianhe Oilfield of the Dongying Depression is systematically summarized using drilling, core, logging, well log and test data, suggesting that the karst reservoirs of paleo--buried hill weathering crust are well developed in Well Miangu 3, which can be vertically divided into vertical vadose zone, horizontal underflow zone and deep sluggish flow zone. The vertical vadose zone is characterized by strong karstification, strong filling and good reservoir potential; for the horizontal underflow zone, strong karstification, weak filling and optimal reservoir potential; and for the deep sluggish flow zone, weak kastification and poor reservoir potential.
