世界深水油气勘探进展与南海深水油气勘探前景

世界深水油气资源丰富，近年来深水油气勘探已成为当今世界油气勘探开发的热点和油气增储上产新亮点，也是当今海洋油气勘探必然发展趋势和油气资源接替的重要战略选区。南海陆坡深水区属我国油气勘探与研究的新区，处于准被动大陆边缘盆地位置，从烃源岩、含油气储盖组合、圈闭及油气运聚条件等综合考量，具备形成大中型油气田的基本地质条件，颇具油气资源潜力，其应是我国油气资源接替的重要战略选区和增储上产的现实区域。在以往研究和所获地质资料的基础上，重点探讨了围绕南海深水油气勘探的关键问题，以期促进和加快南海深水油气的勘探进程。

PROSPECT AND PROGRESS FOR OIL AND GAS IN DEEP WATERS OF THE WORLD, AND THE POTENTIAL AND PROSPECT FOREGROUND FOR OIL AND GAS IN DEEP WATERS OF THE SOUTH CHINA SEA

There are abundant oil and gas resources beneath deep water basements of the world. In recent years, the deep-water oil-and-gas has become a hotspot of the prospecting and exploitation for oil-and-gas and a new window for increasing the reserves and output of oil-and-gas around the world, also the inevitable tendency of marine oil-and-gas prospecting and an important strategical bull＇s-eye of looking for supersede oil and gas resources. The deepwater area of the northern South China Sea slope, a new area of Chinese prospecting and researchment for oil-and-gas, is located on a parapassive margin. In this area, we consider that there are essential conditions for forming medium sized or large scale oil and-gas fields, should be Chinese important strategical bull＇s-eye of looking for supersede oil-and-gas resources, and of increasing the reserves and output of oil and gas, based on the factors such as hydrocarbon source rocks, oil-and-gas reservoir capping assembled, trap and migration conditions, etc. Nevertheless, how about on earth are the potential, scale and foreground for the oil and gas resources in the area？ No one knows the details of these key problems now. The authors carried out some discussions on the key problems in this paper, based on a great deal of geological data and prevenient research achievements, in order to accelerate the prospecting of oil-and gas in the deepwaters of the South China Sea.
