英文摘要	Careful fluid inclusion study were carried out on Yingcheng Formation of volcanic rocks, an important deep seated natural gas reservoir strata in Changling depression, the results showed that there are abundant carbonic fluid inclusions existed in quartz and calcite veinlets developed in this set of volcanic rocks, there are mainly CH4 and CO2 two types were identified by laser Raman microprobe analysis on compositions of single fluid inclusions. Primary as well as secondary CH4 fluid inclusions mainly occurred in veinlet calcite, while CO2 inclusions, however, only found in quartz veinlets and occurred mainly as randomly distributed primary inclusions. In some veinlet quartz, calcite breccias that containing CH4 inclusions have been found, that indicates quartz veins formed later than calcite veins. Based on study of petrological as well as compositional features of carbonic fluid inclusions developed in Yingcheng Formation of volcanic reservoir rocks, we obtained some preliminary conclusions; the deep seated natural gas. fields in Songliao basin were the results of asynchronous charging of CH4 and CO2 gases, the infilling of CH4 predated that of CO2 and primary holes/porosities as well as secondary cracks developed in volcanic rocks served as the main route ways for the charging and accumulating of CH4 and CO2, etc. gases.
