| 摘 要： | 琼东南盆地乐东凹陷烃源岩热史及成熟史研究对乐东凹陷油气资源评价及勘探选区具有指导意义.在盆地地史和热史恢复的基础上,利用EASY％Ro模型模拟重建了琼东南盆地乐东凹陷崖城组烃源岩的成熟史.研究结果表明,琼东南盆地具有较高的古、今地温梯度,且古地温梯度多高于现今地温梯度,有利于烃源岩的成熟与天然气的生成.始新世—早渐新世...

| Abstract: | The study of the geothermal and maturation histories of the source rocks in the Ledong Sag,Qiongdongnan Basin is significant for the hydrocarbon evaluation and decision for exploration areas.Based on geohistory and geothermal history in the sag,the source rock maturation history of the sag is reconstructed by Easy% Ro model.It is indicated that Qiongdongnan Basin has a higher paleo and present geothermal gradient,while the paleogeothermal gradient is higher than the present geothermal which it is of great h... |
