| 摘 要： | 通过对滨海断鼻沙三段、歧北斜坡沙二段和滨海斜坡沙一段流体包裹体均一温度分布特征、烃包裹体产出特征、包裹体和沥青的成因特征的分析,划分出研究区油气成藏期次、成藏时间以及油气藏成因的控制因素,认为研究区具有"两期充注、先油后气,差异聚集、高油低气"的油气成藏模式;油藏分布序列受生烃演化、构造发育的配置关系控制;受大面积分布的岩性圈闭控制,多期砂体叠置,差异聚集是油气藏分布倒置的主要原因。

| Abstract: | This paper analyzes the distribution of homogenization temperature of fluid inclusion,the occurrence of hydrocarbon inclusion,and the genesis of inclusions and bitumen for Es3 in Binhai fault nose,Es2 in Qibei slope and Es1 in Binhai slope;and discriminates hydrocarbon accumulation period,timing and control factors. It is concluded that the study area has the characteristics of "two stages of hydrocarbon filling,oil before gas,differential accumulation,and oil higher than gas";reservoir distribution is subject to evolution of hydrocarbon generation,structure development configuration,and widespread lithologic traps;superimposed multistage sands and differential accumulation mainly contributed to inversed reservoir distribution. |
