摘要

通过对松辽盆地南部5口井井下油气化探测试结果的归纳分析发现:顶空气轻烃指标在气井、油气显示井中检出率较高,在干井中检出率较低;岩屑酸解吸附烃的参评作用并不突出,只能起辅助作用;异常井段的顶空气轻烷烃比值图显示出该地区的气井有偏干气的特征。

Abstract

Test resultes of downhole hydrocarbon geo-chemical exploration from five wells in the south of Songliao Basin show that the identification ratio of light hydrocarbon of top air in gas wells and oil-gas indication wells is higher than that in dry wells. The role of acidolysisabsorption hydrocarbon of rock cutting is only auxiliary in hydrocarbon evaluation. The ratio of light hydrocarbon to alkane of the top air in abnormal well sections suggests that the gas wells of the study area possess the characteristics of dry gas

Key words： South of Songliao Basin; Hydrocarbon geochemical exploration; The ratio of light hydrocar- bon to alkane.
