摘要
渤海湾盆地的油气勘探开发已有40余年的历史,勘探程度不断提高,勘探目标日趋隐蔽,勘探难度不断加大。面对挑战,各探区解放思想、转变观念、调整思路、反复认识、强化预探、加强新技术的推广与应用,近几年来勘探工作获得重大突破,取得了丰硕的勘探成果,滩海勘探、陆上岩性地层油气藏、老区精细勘探、低潜山与火山岩等领域发现了近8×108t级的资源规模。经综合研究与分析,认为渤海湾盆地油气资源潜力仍然很大。富油气凹陷,作为油气勘探的主战场,存在岩性油气藏、滩海、潜山与火山岩,以及老区精细勘探等四大领域,这为“中石油”探区在今后相当时期年均增长探明储量1×108t奠定了坚实的基础。
More than 40 years have passed since the exploration and development in Bohai Bay Basin, with increasing exploration degree. Nowadays, exploration targets become increasingly subtle, and more difficulties need to resolve in exploration process. Facing these challenges, new ideas and new technology or method will be used for us to enhance pre-exploration in different regions. In recent years, important breakthroughs have been made in beach exploration, onshore lithologic-stratigraphic oil-gas reservoirs exploration, accurate exploration in mature areas, deep buried hill and volcanic oil-gas reservoirs, and etc. Nearly 800 million tons of oil resources have been discovered and proven. Based on comprehensive analysis, it is suggested that the large potential of oil/gas still exists in Bohai Bay Basin. Petroleum-rich sags, as major targets for future exploration, include frontiers such as beach, lithologic oil-gas reservoirs, deep buried hill and volcanic oil-gas reservoirs and the mature areas, which will lay a solid foundation for an annual increase of 100 million tons of oil from PetroChina Blocks, Bohai Bay Basin in the long period of future.
