| 摘 要： | 运用流体包裹体测温与磷灰石裂变径迹热史模拟相结合的油气成藏年代学研究方法,系统探讨了鄂尔多斯盆地东北部上古生界油气成藏期次和时间.基于流体包裹体均一温度的分析表明,二叠系砂岩储层总体上经历了2～3期次的油气充注过程；结合单井的热演化史研究,推算油气的充注时间为168～156,148～132,32 Ma.综合分析认为,鄂...

| Abstract: | The homogenization temperature of fluid inclusions and AFT thermal history analysis offers the opportunity to reveal the time of oil-gas accumulation in the Upper Paleozoic of northeastern Ordos Basin.The analysis of homogenization temperature of fluid inclusions shows that the sandstone reservoirs of Permian experienced 2-3 periods of oil-gas charging process.This analysis combined with thermal evolution of single wells indicates the time of oil-gas is 168-156 Ma,148-132 Ma and 32 Ma.Therefore,the Permian ... |
