It is indicated that the salt beds have a bearingupon the hydrocarbon accumulation more than 80%discovered oil-gas reserves of the world[1]. The saltbeds can change the occurrence of overlying horizons,forming various structural traps[2,3]. The salt bed itselfis the most effective caprocks. The deposits ofhigh-saliniferous environment may have favorablepetroleum-generating conditions[4]. The salt beds withlow specific thermal conductivity may result in highergeothermal gradient of sub-salt str… 相似文献

宽扎盆地油气地质特征 总被引:1,自引:0,他引:1
安哥拉宽扎盆地是典型被动大陆边缘盆地,完整经历了前裂谷阶段、裂谷阶段、过渡阶段及漂移阶段等4个构造演化阶段,形成了盐下、盐间和盐上3套沉积层序,并各自形成含油气系统。在对宽扎盆地构造演化、沉积特征及油气成藏条件进行分析后认为:宽扎盆地盐下、盐间和盐上3套沉积层序的油气成藏主控因素分别为拉伸断陷、盐隆起及盐构造运动;宽扎盆地盐下有利勘探区为盆地东部白垩系地堑构造区,盐间有利勘探区为盆地中东部盐隆发育部位,盐上有利勘探区为盆地东部古近系和新近系地堑发育部位;宽扎盆地今后勘探工作重点应放在盆地东部白垩系地堑构造区的盐下碳酸盐岩储层目标。 相似文献
