摘　　要：于标准剖面新部署钻探营城组上部的全取心钻孔揭示,营城组三段厚205.70 m,营城组二段厚48.75 m(未钻穿)。主要岩石类型包括火山熔岩类、火山碎屑熔岩类、火山碎屑岩类、沉火山碎屑岩类和沉积岩。整个井段火山喷发划分为3个旋回10个期次。火山岩的有效储集空间包括4种11类,储集空间组合关系有4种,孔缝直接连通型是最好的储集空间类型。用岩心、薄片和物性测试划分出4种孔隙分布和7种孔隙结构类型,单峰偏粗态型和双峰态型孔隙分布最好。低排驱压力-粗孔喉为最好的孔隙结构类型。The whole coring Ying- 3 D1 well was drilled in the standard section for investigating of the upper two members of Yingcheng Formation. The overall thickness of the third member is 205.70 m and the drilled thickness of the second member is 48.75 m （unpenetrated）. There are mainly five types of volcanic rocks including lava,pyroclastic lava,pyroclastic rock,sedimentary pyroclastic rock and sedimentary rock. Volcano eruptions in this well have been divided into three cycles and ten periods. The reservoir spaces have been divided into four types and eleven subclasses. Further more, there are four combination patterns of reservoir spaces. The most favorable is pores directly connect to the fissures. Four types of pore distribution and seven types of pore structures have been recognized with core observation, microscope image analysis and mercury intrusion method. The single-bias with coarse-kurtosis and double kurtosis type have the best pore distribution. The best pore structure is of the low displacement pressure-coarse pore throat.
