| 摘 要： | 为寻求保持探明石油地质储量持续稳定增长的有效资源接替勘探领域,对鄂尔多斯盆地三叠系延长组待探明资源量的分布进行综合分析。通过对延长组5大沉积体系资源量和探明石油地质储量分布特征的对比分析,指出延长组中、下组合是近期油气勘探的主要接替层系。其中湖盆中部的长6、长8油层组和西北、西南沉积体系的长8油层组是近期增储上产的现实勘探领域;东北沉积体系的长8油层组和全盆地的长9—长10油层组是保证未来5~10年储量稳定增长的主要勘探接替领域。

| Abstract: | In order to investigate the distribution of awaiting proved resources of Yanchang Formation of Triassic in Ordos Basin and explore effective exploration regions of resources replace for keeping up a steady increase in the proven petroleum geological reserves,the article analyse the characteristics of resources and proven petroleum geological reserves in five depositional systems of Yanchang Formation.The results indicate that the middle and lower associations are the main replace regions,in which the Chang 6,Chang 8 oil layers in the middle part of the basin and the Chang 8 oil layer in the northwest and southwest depositional systems are actual exploration areas keeping production and adding reserves.The Chang 8 oil layer in the northeast depositional systems and the Chang 9,Chang 10 oil layers in the whole basin are the main replaced regions to keep steadily ascending in the following five to ten years. |
