塔里木盆地满加尔凹陷下古生界烃源岩的再认识

中国石油天然气股份有限公司在第三次油气资源评价成果和剩余油气资源领域分布评价基础上,提出了岩性-地层油气藏、前陆盆地冲断带,叠合盆地中下部组合和成熟探区富油气凹陷(区带)四大勘探领域.指出岩性-地层油气藏已成为油气储量增长的主体,前陆盆地冲断带是寻找大发现的重要领域,叠合盆地中下部组合增储地位日趋重要,富油气凹陷(区带)精细勘探潜力仍然很大.分析认为未来剩余油气资源主要分布在岩性-地层油气藏、叠合盆地中下部组合、前陆盆地、富油气凹陷(区带)、陆上新区新盆地、南海南部海域和非常规资源等七大领域,其中前四大领域勘探潜力仍然很大,是未来油气增储上产的重点领域;陆上新区新盆地、南海南部海域及非常规资源将是未来实现中国石油资源战略接替的重要领域.

PetroChina key exploration domains: Geological cognition, core technology, exploration effect and exploration direction

On the basis of the third evaluation on hydrocarbon resources and the distribution estimation of residual oil/gas resources, PetroChina puts forward four key exploration domains which are litho-stratigraphic reservoirs, foreland thrust belts, middle and lower combinations of the superimposed basins, and hydrocarbon-rich depressions or plays in the mature exploration area. The litho-stratigraphic reservoir has become the main body of the proved reserves growth, the foreland thrust belts are the important domains for finding significant discoveries, the middle and lower combinations in the superimposed basins have increasingly important status in increasing geological reserves, and the fine exploration in hydrocarbon-rich depressions or plays have also prodigious exploration potential. Future's residual hydrocarbon resources are mainly distributed in seven domains, which are large-scale litho-stratigraphic reservoirs, hydrocarbon-rich depressions (plays) in rift-subsidence basins, foreland thrust belts, middle-lower combinations in the superimposed basins, onshore new exploring areas and new basins, south areas of South China Sea, and unconventional resources. Among them, the former four domains have great exploration potential and are the important areas for reserves and production growth, and the latter three domains are the important fields of realizing resources strategic relay for PetroChina in the future.
