我国陆上油气勘探领域变化与启示——过去十余年的亲历与感悟

Changes and Enlightenment of Onshore Oil/Gas Exploration Domain in China——Experience and Perception in the past decade

过去十余年间,我国陆上油气勘探领域发生了巨大变化,以"满凹含油"论的提出为标志,勘探领域已经由以"二级构造带"为主转为以富油气凹陷为中心的全盆地勘探;有机质"接力成气"理论指导推动叠合盆地深层高—过成熟层系也取得突破,成为未来储量增长的重大接替领域。陆上未来找油气领域将进入3个并重发展阶段,即构造油气藏与岩性地层油气藏、深层与中浅层以及常规油气与非常规油气资源并重发展。油气成藏理论的持续创新与工程技术的不断进步仍然是实现油气储量稳定增长的关键。

China＇s onshore oil/gas exploration domain has been changing a lot in the past decade. Before the advancement of ＂sag-wide oil- bearing＂ theory, ＂secondary tectonic belt＂ was the major domain of exploration. After that, the domain has been transferred to hydrocarbon rich depressions. Besides, breakthrough has been made in high mature and overmature strata of deep superimposed basins, based on the theory of ＂successive generation of natural gas from organic materials＂. So high mature and overmature strata became the major substitute area of reserves growth in the future. Future onshore oil and gas detection will lay equal stress on the structural reservoirs and lithologic stratigraphic reservoirs, the deep and mid-shallow layers, and the conventional and unconventional oil/gas resources. Sustained innovation of oil/gas accumulation theory and steady progress of engineering technology will still be the key to realizing stable growth of oil/gas reserves.
