摘要
准噶尔盆地西北缘红山嘴地区出现异常气测录井显示,通过对这些特殊井选取岩心样品和原油样品进行地化录井特征分析,得出该区油质整体偏重,热解色谱谱峰主要集中于S21、S22,异常幅度明显;热解-气相色谱谱图基线呈明显穹窿,不可见轻烃组分峰形。该研究对发现、识别油层针对性强,对红山嘴地区发现新的油气层有重要意义。
Abnormal gas logging display makes oil-gas-water interpretation and discovery of oil reservoirs difficult in the Hongshanzui oilfield, Junggar basin. This study selects the core and crude oil samples of anomalous display to analyze the geochemical logging characteristics in order to find out the characteristics of oil reservoir with anomalous display in this area. From the study it is concluded that the peaks spectra of thermal chromatography for crude oil with high density in the Hongshanzui oilfield focus on S21 and S22. The peak spectra of gas chromatography are dome-shaped and light hydrocarbon components are invisible.
