Based on the hydrocarbon accumulation conditions of erlian basin , integrated analyses including burial history , thermal history and characteristics of diagenetic fluid inclusions of oil reservoir in three main depressions are conducted , and in terms of quantitative analysis of homogenization temperature of fluid inclusions , the formation stages of the oil accumulations are determined 摘要在對內蒙古二連盆地3大凹陷成藏條件和埋藏史、熱史分析研究基礎上,結合儲層成巖流體包裹體特征分析,利用流體包裹體均一化溫度定量分析方法確定了二連盆地油藏的成藏期,并將二連盆地巖性油藏與構造油藏的成藏期進行了對比研究。
