摘　　要：利用傅里叶变换显微红外光谱法(FT-IR),对苏北盆地S-F油田典型烃类流体包裹体求取亚甲基与甲基的峰面积比值,并依此进行油气包裹体成熟度的判断。结果表明:波数范围内CH2/CH3、Xinc、Xstd的值越小,包裹体中有机质的成熟度越高。对研究区内三口井的分析揭示:FSX1井经历了至少两次油气充注,两期的油气包裹体成熟度分别为低成熟和高成熟;SHA18井、SHA19井油气包裹体成熟度分别为高成熟和低成熟。For typical hydrocarbon-fluid inclusion in S-F oilfield,Subei Basin,its peak area ratios of both methyl and methylene are calculated by means of the Fourier transform infrared(FT-IR) spectrum method.And its maturity is also determined.Results show that within the range of wave number,the smaller the CH2/CH3,Xincand Xstdvalues are,the higher the organic matter's maturity in fluid inclusion is.In addition,the analysis on three wells in the study area reveals that(1) for FSX1 well which experienced hydrocarbon fillings at least twice,the maturity of fluid inclusion during two fillings is low and high,respectively;and(2) for both SHA18 and SHA19 wells,their maturity is high and low,individually.
