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。
At present, the continental rift basin in eastern China has entered the stage of stratigraphic-lithologic trap exploration. The analysis of the exploration characteristics of the major continental rift-bearing petroliferous basins in eastern China shows that the stratigraphic-lithological trap exploration in the continental rift basin is as follows Characteristics: strong basin divisions and many types of traps; high exploration potential, high technical requirements and long period of knowledge; long exploration life and multiple exploration peaks. Although stratigraphic-lithologic reservoir exploration has become a hot spot in the current research, it is still far from enough for the prospecting needs of highly mature exploration areas. This research has a long way to go.
