依据对千米桥潜山流体包裹体的分析结果并结合板桥凹陷相邻地区的构造演化史、生烃史和潜山凝析气藏地球化学特征 ,判定千米桥潜山共有四期油气充注过程。第一期充注的是来自板桥凹陷成熟度较低的天然气 ,充注时期大致在沙一段―东营组时期 ;第二期充注的是来自板桥凹陷生成的凝析油气 ,时间大致在馆陶末―明下段时期 ;第三期充注了来自板桥凹陷高成熟凝析油气 ,时间应在明化镇组时期 ;第四期充注了来自板桥凹陷和岐口凹陷的高成熟天然气 ,充注时间为明化镇组至更晚的时期。

It is identified that four oil gas injection terms exist for Qianmiqiao buried hill on the basis of the Qianmiqiao buried hill fluid inclusion analysis result, in combination with adjacent Banqiao sag′ tectonic evolution history, oil generating history, the buried hill condensate gas reservoir geochemistry and its distribution features. The first term gas is from lower mature natural gas of Banqiao sag, which time is between Shayi member of Shahejie formation and Dongying formation depositional period.
