Because more oil and gas are required than it was,people begin to explore and develop new oil-field in deep water and ultra deep water area.

Concept of exploration for oil and gas reservoir and oil testingtech at floatin g deck on deep water are introduced, some aspects of technical feature of testing at deep water region, surface system to acquiring production, down hole and un der water testing string, testing procedure which makes a technique preparation for exploration at deep water.

With the technology advancement and human being's progressive cognition of the ocean petroleum resources,the offshore oil exploration and exploitation are being approached from shallow water to deep water,even to the ultra-deepwater.
