作为最早进行油气勘探的地区之一,六盘山盆地在许多关键问题上还存在分歧和争议,中生代盆地的主要发育期次和盆地的主要勘探目的层是争论的焦点问题之一。文章在简要回顾六盘山盆地的勘探历程和总结归纳前人成果认识基础上,根据海参1井最新的钻探成果和发现,认为六盘山盆地是一个白垩系为主的盆地,白垩系具有一定的生烃能力和成藏条件,建议将研究重点和勘探主要目的层转向白垩系。 As one of the earliest oil and gas exploration areas, there are still many disagreements and controversies on many key issues in the Liupanshan Basin. The main development stages of the Mesozoic basin and the main exploration target layer of the basin are one of the most debated issues. Based on a brief review of the exploration history of the Liupanshan Basin and a summary of previous achievements, based on the latest drilling results and discoveries in the Hai-1 well, it is believed that the Liupanshan Basin is a Cretaceous-dominated basin with Cretaceous Hydrocarbon capacity and reservoir forming conditions, it is proposed to shift the focus of research and exploration to the Cretaceous.
