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.%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 Es, 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.
