摘要
采用显微荧光技术以及流体包裹体显微测温技术,结合鄂尔多斯盆地长9段储层油气埋藏史及地热史演化过程模拟,确定了该区油气运移的主要期次。系统分析表明,鄂尔多斯盆地长9油层组油气主要经历了一期油气充注,只有峰2井存在较弱的二期油气充注;该油层组构造热事件主要发生在中生代晚期的早、中白垩世（130-100 Ma）。
Based on the evolutionary process simulation of burial history and geothermal history, the paper studies oil and gas pool formation in Chang 9 Formation in Ordos Basin with microfluorometric technology and microscopic thermometry technology of inclusions. The result shows that the oil-gas accumulation in the formation is characterized with one stage infilling except Feng 2 well with feeblish late-stage infilling. It is suggested that tectonic heat event should have occurred in 130-100 Ma of early-Cretaceous and middle-Cretaceous period.
