Abstract: Exploration and development of oil and gas resources in deep sea area is an important foremost position of petroleum industry. Deep water operation is more risky as compared with exploration and drilling operation in continental shelf and onshore. Exploration and development in deep and ultra-deep water area must depend on advanced technologies and strong economic strength. This paper analyzes the technical aspect of exploration and development in deep sea area worldwide and the difficulties in drilling and exploration as well as development, building of oil platform, prediction and avoidance of natural disaster, points out many challenges including peculiar marine environment, complex oil and gas reservoir storage, efficient and secure technical support and equipment support as well as logistical service with facing deep sea drilling in the future, makes a comparative analysis of international and domestic technology gap in this field, briefly introduces the problems in China's offshore oil and gas exploration and development, and proposes some suggestions to improve China's capability in deep sea exploration
