摘要
利用显微镜红外光谱(简称Micro FTIR)技术可测定单个包裹体的成分、分子结构和其中油气包裹体的成熟度。通过Micro FTIR、包裹体的镜下鉴定技术,对海拉尔盆地和2井样品,以及齐家古龙凹陷的英51井样品的包裹体进行了分析,利用红外光谱的CH2a/CH3a之比、Xinc、Xstd等参数并结合包裹体的镜下鉴定提出了和2井有过两次油气充注,并以第二次油气充注为主,主要是轻质油和少量气。英51井有过三次油气充注,以第二次油气充注为主,主要是中质油和少量气。
Microscope-infrared spectroscopy (MicroFTIR) technique can be used to measure the component and molecular structure of inclusion enclave and the maturity of hydrocarbon inclusion enclave. This paper analyzes the inclusion enclaves of samples of Well He 2 in Hailaer Basin and Well Ying 51 in Qijiagulong Sag using MicroFTIR and microscope identification techniques. It proposes 2 times of hydrocarbon infilling in Well He 2 using CH2a/AH3a ratio, Xinc and Xstd combining microscope identification of inclusion enclaves of infrared spectroscopy. The second time of filling is principal one, containing light oil and a little gas. Well Ying 51 has three times of hydrocarbon filling, in which the second one is principal one, containing medium oil and a little gas.
