柴达木盆地油气资源战略调查成果与下步工作重点
|
摘要
柴达木盆地是中国七大含油气陆相盆地之一,油气资源总量丰富,勘探潜力巨大。柴达木盆地油气资源战略调查及评价项目研究工作开展2年以来,取得了重要的成果和认识:德令哈断陷内大面积分布中—下侏罗统烃源岩;盆地东部石炭系具有生烃能力;盆地北缘东段红山地区地震勘探采集到较好品质的资料;狮子沟地区天然地震勘探得到初步成果;综合应用地震、钻井等资料,确定了狮子沟构造的深层构造。下一步工作的重点是进一步加强盆地东部石炭系评价的力度,深化狮子沟、红山、德令哈等地区深层构造的研究及圈闭资源量评价工作。
The Qaidam basin is one of the seven petroliferous continental basins in China. It is rich in oil and gas resources and has a considerable exploration potential. Since the research project of strategic investigation and evaluation of oil-gas resources in the basin was carried out two years ago, the following important outcomes and knowledge have been obtained: Middle and Lower source rocks are distributed over large tracts in the Delingha fault depression; carboniferous rocks in the eastern part of the Qaidam basin has the hydrocarbon-generating capacity; high-quality materials have been collected during seismic exploration in the Hongshan area in the eastern part of the northern margin of the Qaidam basin; deep structure of the Shizigou structure has been determined through comprehensive use of seismic and drilling data. The future work will focus on further strengthening efforts of the evaluation the Carboniferous of the eastern part of the basin, conducting a more intensive study of the deep structure in the Shizigou, Hongshan and Delingha areas and deepening the evaluation of resources in traps.
