There exist abundance metal, energy and creature resources in the extensive sea. Besides the general petrology and natural gas, some unconventional resources are focalized over the world; moreover, it brings the new circle “blue-revolution”. It hold well foreground of sciences and commercial application such as oceanic polymetallic concretion, cobaltic agglomeration, polymetallic sulfide, natural hydrate and deep-sea hot spring creatures. The abundance resources were called the strategic substituted energy of human sustainable development. On the basis of sea resources analysis, some argues of important scientific theory and technological assembly in the exploitation of oceanic resources are discussed in the paper, such as the technological assembly of deep-sea creature resources commercial applications, the study on the hydatogenesis of sea bottom, the study on the reaction between water and rocks, the discriminating and exploitation technology of natural hydrate and solid metallic deposits. The sea high technology was established on the basis of modern sea technological theory and the related scientific system. The innovative advancement of important theory and technological assembly will hold up sea science and sea project.
