Source rock evaluation of coal - measures strata in kuqa depression of tarim basin 庫車坳陷侏羅系煤系烴源巖評價
Source rock evaluation and oil - source rock correlation in well yangcan1 of dayangshu basin 大楊樹盆地楊參1井烴源巖評價及油源對比
Lot of geochemical data and petroleum exploration practices have shown that great risk will be introduced from a direct application of thermal simulation results of source rocks or kerogens in source rock evaluation 大量研究及油氣勘探實踐已經(jīng)證明,將干酪根生烴熱模擬實驗結果直接應用于含油氣盆地烴源巖評價存在很大風險。
Apart from in lacustrine basins in eastern china , sequence stratigraphic geochemistry is of especially important significance in source rock evaluation in some basins of western china , where only a few wells were drilled , and insufficient source rock cores are available 層序地層地球化學研究不僅對中國東部老油田隱蔽油氣藏的勘探工作具有重要的意義,對勘探程度不低、鉆井少、源巖取心少的西部含油氣盆地中的烴源巖評價工作更為有效。
This study used some techniques such as organic geochemistry bulk composition combined with molecular geochemistry , source rock analysis and evaluation of organic petrology , carbon isotopes of organic matter , petroleum geology inference etc . the emphasis is mainly concentrated on the source rocks belong to the shahejie formation of pal eocene , including the source rock evaluation of denan region , geochemistry of the source rock , biomarkers of immature oils and source rocks . then the ancient geological environment was established and immature oil formation mechanism was proposed . following results have been tentatively proposed in this thesis : 1 ) based on the organic petrology studies , most of source rocks in this region is belong to immature source rock 本項研究以德南洼陷重點烴源巖- - -下第三系沙河街組為對象,應用有機地球化學理論與方法對其有機質(zhì)類型和豐度、成熟度、生烴潛量等進行研究;通過特征生物標志化合物的分析,闡明研究區(qū)未熟-低熟烴源巖母質(zhì)構成、沉積環(huán)境和成熟演化;通過油源對比和生烴條件綜合分析,提出本區(qū)烴源巖生烴機制,建立未熟-低熟烴源巖有機質(zhì)生烴模式。
