中国东部陆相断陷盆地圈闭勘探特点分析

Stratigraphic-Lithologic Trap Exploration in Continental Rift Basins,East China

目前中国东部陆相断陷盆地已进入地层—岩性圈闭勘探阶段,对中国东部主要陆相断陷含油气盆地的勘探特点分析表明,陆相断陷盆地地层—岩性圈闭勘探具有如下特征:盆地分割性强,圈闭类型多;勘探潜力大,对技术要求高,认识周期长;勘探寿命长,有多个勘探高峰。虽然地层—岩性油气藏勘探已经成为当前研究的热点,但和高成熟探区的勘探需要相比还远远不够,该项研究任重而道远。

It is paid more attention to stratigraphicqithologic trap in exploration of continental rift basins in east China. The exploration experience in continental rift basins in east China indicates that the stratigraphic-lithologic trap in continental rift basin has three features as follows：① Divided strongly basins, types of stratigraphic-lithologic traps; ②Great potential of exploration, high technology requirement and long time recognition; ③Long-time exploration, multiple exploration peak. Although the exploration of stratigraphic-lithologic trap has become present hot point, it is still a long way to go forward, comparing with exploration of mature basin.
