深水油气勘探是当今油气勘探的主要方向,是世界油气增长主要来源区。目前深水油气勘探以被动陆缘盆地为主,勘探区带以有油气发现浅水油气区向深水区的延伸为主,圈闭类型以大型构造和岩性圈闭为主,储层以第三系深水扇体类型的高孔高渗储层为主,油气类型以油为主。深水油气勘探具有由深水向超深水,由单一向多元化发展并综合最新勘探开发技术的发展趋势。
Deepwater oil and gas exploration is the main direction of oil and gas exploration today, is the world’s main source of oil and gas growth. At present, deep-water oil and gas exploration is dominated by passive marginal basins. In the exploration area, the discovery of shallow water-oil and gas zones extends mainly to deep-water areas with oil and gas. The trap types are dominated by large structures and lithologic traps, and the reservoirs are characterized by Tertiary Deep-hole fan-type high-porosity and high permeability reservoir-based oil and gas-based oil-based. Deepwater oil and gas exploration from deep to ultra-deep water, from a single to a diversified development and integrated development of the latest exploration and development trends.
