摘要
通过对琼东南盆地崖１３－１气田陵水组三段储层砂岩自生石英中有机包裹体的类型分布、均一温度及成分等的研究认为，崖１３－１气田天然气开始运移的时间在上新世，运移深度为３．０～３．３ｋｍ，此时尚未形成气藏；大量运聚发生在上新世末—第四纪，运移深度为３．４～３．９ｋｍ，主要聚集期为第四纪。根据有机包裹体的成分特征对储层流体介质及气源进行了初步分析。
The type distribution,homogeneous temperature and components of organic inclusions in authigenic quartz of sandstone,member 3,Lingshui formation show that gas migration began at Pliocene,in Ya 131 gas field.At that time the of buried depth strata was about 3.0 to 3.3 km,gas reservior was not formed yet.The largescale migration occurred in the end of Pliocene to Quaternary,with its depth about 3.4 to 3.9 km.The main accumulation stage is Quaternary.Based on the component characteristics of organic inclusions,the fluid media and gas source are discussed.
