| 摘 要： | 宜川—旬邑地区显示油气丰富,但是实际勘探效果不佳,通过宜川-旬邑地区延长组长6~长8储层流体包裹体岩相、均一温度、盐度的研究表明,该区主要发育液烃包裹体和气液烃有机流体包裹体。流体包裹体主要分布在石英次生加大边与石英颗粒裂纹、方解石胶结物和裂缝充填物中;包裹体个体多为5~15μm,均一温度为49~127℃,平均89℃。80%以上样品的含油流体包裹体丰度(GOI)大于或等于1%,其中近40%样品的GOI在5%以上。流体包裹体总体偏向低盐度,包裹体盐度与均一温度间的相关性差。结合延长组成岩作用、热史和埋藏史分析指出,延长组发生过广泛的油气运移与充注事件,充注时间主要在早白垩世早期—早白垩世晚期;油藏具储层边致密、石油边成藏的特点,受后期构造运动的影响,原始封闭体系遭到破坏,在方解石胶结物不甚发育且原生粒间孔隙保存较好的区域,有望获得油气勘探的突破。 |
| 关 键 词： | 流体包裹体 均一温度 成藏期次 储层流体 延长组 |

| Abstract: | Based on microscopic observation,including homogenization temperature and grains with oil inclusions of the fluid inclusions of Chang6-Chang8 in the Triassic Yanchang formation in the Yichuan-Xunyi area,this study showed that liquid hydrocarbon fluid inclusions and gas-liquid hydrocarbon fluid inclusions,which mainly distribute in the secondary quartz and quartz particles increased edge crack,carbonate calcite cement and fracture fillings,are relatively abundant.The size of these fluid inclusion are mainly ... |
