| 中文摘要: |
| 辽河外围盆地大多属晚中生代早期发育的裂谷断陷型盆地。总体上,这些盆地的形成与演化受以裂陷作用为主导的构造运动所控制,主要经历了裂谷发育和坳陷发育两个阶段的沉积作用,后者仅局限于开鲁盆地。在地质地球化学方面,外围盆地沉积构造复杂,多次遭受抬升剥蚀运动,地质构造运动所伴随的热历史复杂,曾有过多期较强的区域性火山活动,使该区烃源岩热成烃过程变得极为复杂,且大多数盆地属于狭小条状小型断陷盆地。近源粗碎屑发育,有机质中陆生高等植物所占比例较大。本次研究选择了开鲁盆地中最大的陆家堡坳陷,也是目前辽河外围盆地中油气资源潜力最好的地区之一,主要进行了烃源岩的有机质丰度和有机质类型研究。 |
| 英文摘要: |
| Most of the basins in the surrounding area of Liaohe River are of rift-fault basin developed in Upper-Mesozoic. Their formation and evolution were controled by tectonic movement.The Lujiabu depression is one of the best potential petroleum resource targets.The purpose of the present paper is to evaluate the hydrocarbon source rocks and provide the petroleum exploration in this area with some scientific data dealing with the abundance of organic matter and kerogen types.An evaluation on the potential hydrocarbon generation of the source rocks has been made. |
