| 摘要: |
| 基于野外调査、沉积构造演化历史分析、有机质成熟度资料,运用改造盆地研究方法和油.气评价思路,研究胶 莱盆地的后期改造作用，并对每一种类型的改造强度及分布范围进行划分和评价，最后对盆地主要构造单元含油气 系统勘探远景进行分析评价。结果表明:胶莱盆地主要改造类型有热力改造、叠合深埋改造、构造变形改造和隆升 剥蚀改造4种;胶莱原型盆地后期改造作用强烈，盆地油气主要保存于后期叠合深埋区,高密凹陷中的姜山次洼陷和 莱阳凹陷具有一定的油气勘探前景。 |

| Abstract: |
| Based on field observations, sedimentary-tectonic evolution analysis and oi^anic maturity data，reformation of Jiaolai Basin was researched by using research method of basin reformation and estimation ideas of hydrocarbon preservation. The intensity of each reformation type was divided and spatial distribution of each reformation type was described in Jiaolai Basin. At last, the exploration potentiality of petroleum system was evaluated for main tectonic unit. The results show that there are 4 reformation types including thermal reformation, superimposed overburial, tectonic deformation, uplift and denudation in Jiaolai Basin. The later reformation of Jiaolai Basin was strong and hydrocarbon mainly preserved in superimposed overburial areas. Jiangshau sag in Gaomi depression and Laiyang depression might have petroleum exploration potentiality. |
