| 摘 要： | 北部湾盆地涠西南凹陷C洼流沙港组烃源岩热史及成熟史研究,对C洼深水油气勘探具有指导意义。在恢复涠西南凹陷C洼地史和热史的基础上,利用EASY%Ro模型计算了流沙港组烃源岩的成熟度史。研究结果表明,在涠西南凹陷发展的裂陷阶段初始期热流值较高,最大值约为77mW/m2,其后热流值逐渐减小,现今热流值约为54mW/m2;涠西南凹陷C洼流沙港组烃源岩开始生烃(Ro=0.5%)时间为51MaBP,达到生烃高峰(Ro=1%)时间为42MaBP,达到高成熟演化阶段(Ro=1.3%)时间为17MaBP;对比涠1井流沙港组烃源岩演化特征,处于C洼深水勘探区的流沙港组烃源岩成熟度较高,生烃能力较强,拥有广阔的油气勘探前景。

| Abstract: | It is significant to study the source rock maturity history in the C sag of the Weixinan depression for the deep water exploration in this area of Beibuwan basin.Based on geohistory and thermal history of the C sag,the source rock maturity history of the sag is reconstructed with the usage of Easy%Ro model.The studies indicate:(1)In the early rifting stage,the heat flow in the C sag of the Weixinan depression reached the maximum(77 mW/m2),then decreased gradually and is about 54 mW/m2 at present.(2)The Lius... |
