摘要: 通过火山岩岩心观察和镜下鉴定及全岩化学分析,结合测井资料对徐深气田营城组火山岩储层的岩性、岩相、岩石物性特征进行了研究。该区发育的火山岩类型有13种,测井资料可识别7种, 储集空间类型主要划分为11种。火山岩的岩石类型、岩相以及火山岩的次生改造是影响营城组火山岩储集性能的重要因素,好储层岩性为流纹岩、球粒流纹岩、流纹质熔结凝灰岩和流纹质凝灰岩,升平和兴城南部以喷溢相的(球粒)流纹岩为主,兴城北部以爆发相的(熔结)凝灰岩为主。

Abstract: Xushen Gas Field is the largest volcanic reservoirs ever discovered by now in China, with proven geological reserves more than 100 billion cubic meters. Through volcanic rock core observation, microscope identification and whole rock chemical analysis, the lithology, lithofacies and petrophysical properties of volcanic rocks in Yingcheng Formation are studied based on well logging data. There are 13 volcanic rock types, and seven of them can be identified by well logging data. Reservoir space types are classified into 11 types. Rock type, lithofacies and secondary reformation of volcanic rocks are important factors affecting volcanic reservoir properties in Yingcheng Formation. The reservoir lithologies with good quality include rhyolite, pyromeride, rhyolitic ignimbrite and rhyolitic volcanic tuff. Pyromeride of effusive overflow facies is mainly distributed in Shengping and south Xingcheng, and ignimbrite of eruption faciesis mainly developed in north Xingcheng.

Key words: Songliao Basin, Xushen Gas Field, volcanic reservoir, Yingcheng Formation, reservoir space
