【摘要】 应用储层岩石烃类流体包裹体测试技术,对英吉苏凹陷侏罗系气藏进行了重建流体历史分析研究。包裹体古流体状态分析表明,成藏流体具高矿化度、高密度性质,气态烃包裹体较液态烃包裹体捕获温度高,充注期晚,且占绝对优势。液态烃的化学组成表现出成熟度较低,水体盐度较高,不同地区母源输入存在差异的特点,与早期充注相一致。更多还原

【Abstract】 Fluid history of Jurassic gas reservoir in Yingjisu sag is reconstructed and studied through testing hydrocarbon inclusions in reservoir rocks. Based on status analysis of fossil fluids in inclusions, it is believed that the reservoir fluids are characterized by high salinity and high density. Gaseous hydrocarbon inclusions would have been trapped at a higher temperature and at a later time than liquid hydrocarbons and would have been in extreme predominance. The chemical compositions of liquid hydrocarbons are characterized by relatively low maturity, relatively high water salinity and difference between parent-source inputs in different areas, and are in accordance with early hydrocarbon charging.更多还原
