柴达木盆地石油资源现状及发展战略

Petroleum Resource Status and Development Strategy in Qaidam Basin

柴达木盆地位于青藏高原北部,是中国陆上七大含油气盆地之一,油气资源丰富。根据第三次资源评价结果,盆地油气资源量为46·5×108t,其中石油资源量为21·5×108t,目前石油的探明率为14·8%,说明柴达木盆地具有较大的资源发现潜力。由于柴达木盆地烃源岩各具特点,储集类型多样,油藏特征各异,又可将柴达木盆地分为以侏罗系为烃源岩和以第三系为烃源岩的两大含油系统。因此在未来5年中,青海油田公司将在以下4个重点区域开展勘探工作:柴西南构造岩性区;阿尔金山前带;狮子沟-油砂山构造带;潜伏构造带。

Located in the northern part of Qinghai-Tibet Plateau , the Qaidam Basin is one of the seven petroliferous basins onshore in china. Oil and gas resources are abundant in the Qaidam Basin. According to the third petroleum assessment, there are 4.65 billion tons of total oil and gas resources in the Qaidam Basin. Among them the amount of petroleum resource is 2.15 billion tons, and currently the proven rate of petroleum resource is 14.8%. It shows that a large potential for oil resource exploration still exists in Qaidam Basin. The Qaidam Basin can be divided into two types of petroliferous systems based on the Jurassic source rock and Tertiary source rock due to the diversity in the source rock and reservoir types, difference in reservoir's characteristics. So the four strategic key fields for oil exploration in the next five years are put up by Qinghai Oilfield Company: ①The tectonic-lithological belt in the south-west of Qaidam Basin; ②The Alking front-mountain zone; ③The tectonic belt from Shizigou to Youshashan ; ④The buried tectonic zone.
