【摘要】：通過對隆鄂尼地區(qū)油砂的孔隙度及含油率進行統(tǒng)計,研究了隆鄂尼地區(qū)油砂地質(zhì)特征。研究發(fā)現(xiàn),研究區(qū)為低孔超低滲儲層,與國內(nèi)典型油砂礦相比含油率較高、油氣保存條件好,是油砂勘探開發(fā)有利區(qū)域。選取12件隆鄂尼地區(qū)LK-5井的油砂樣品進行色譜—質(zhì)譜分析,進一步了解研究區(qū)地化特征。實驗結(jié)果表明:隆鄂尼地區(qū)油砂受到微生物降解,降解程度屬1級;油砂與源巖母質(zhì)類型相關性好,母質(zhì)來源于海相有機質(zhì),母質(zhì)類型屬混合源,且高等植物的貢獻較大;油砂樣品的有機質(zhì)沉積環(huán)境為咸水還原海相環(huán)境;油砂油達到成熟階段。研究成果為隆鄂尼地區(qū)油砂資源評價提供了科學依據(jù)。
[Abstract]:Based on the statistics of the porosity and oil content of oil sands in Longni area, the geological characteristics of oil sands in Longni area are studied. It is found that the study area is a low-porosity and ultra-low permeability reservoir, and its oil content is higher than that of typical oil sands in China. It is a favorable area for oil sand exploration and development. Twelve samples of oil sand from LK-5 well in Longni area are analyzed by chromatography-mass spectrometry. The results show that the oil sands in Longni area are degraded by microorganism, and the degradation degree is of grade 1. The oil sand has good correlation with the source rock parent material type, the parent material comes from marine organic matter, and the parent material type belongs to mixed source. The organic matter sedimentary environment of oil sand samples is saltwater reduced marine environment and oil sand oil reaches mature stage. The research results provide scientific basis for evaluation of oil sand resources in Longni area.
