辽河坳陷西部凹陷古近系致密油形成特征及勘探实践

Formation characteristics and exploration practice of Paleogene tight oil in Western Sag of Liaohe Depression

通过对辽河坳陷古近系碳酸盐岩致密油构造、沉积储层特征以及致密油成藏分析基础上,开展实际钻探工作,取得了较好的经济效益。致密油作为当前油气勘探的重要领域,是未来重要的油气储量接替区,因此加强对致密油形成特征研究,对其它陆相盆地碳酸盐岩及页岩致密油勘探提供可借鉴的宝贵经验。

Based on the analysis of structure,sedimentary reservoir characteristics and reservoir formation of Paleogene carbonate tight oil in Liaohe Depression,actual drilling work has been carried out and good economic benefits have been achieved. As an important field of oil and gas exploration,tight oil is an important oil and gas reserve replacement area in the future. Therefore, strengthening the study of the formation characteristics of tight oil can provide valuable experience for the exploration of carbonate and shale tight oil in other continental basins.
