摘　　要：深水海域油气资源丰富,已成为当前热门的油气勘探领域。深水油气产量及所占比重不断增长,全球深水油气产量从1996年的不足2×108bbl增长到2005年的14×108bbl,全球深水油气产量占海洋油气总产量的比重分别由2004年的10%和7%,将增至2015年的25%和12%。深水勘探是当前油气勘探成功率最高、效益最好的勘探领域。与此同时,随着深水油气勘探的逐渐深入,也面临着越来越多的各种难题,如油藏规模越来越小、油藏流体越来越复杂、作业海域环境越来越恶劣,以及对技术的要求越来越高等。为了解决这些问题,高分辨率三维地震技术、四分量/四维(4C/4D)地震技术、大位移水平井及分支井技术、智能完井技术、各种深水作业平台以及越来越智能化的海底生产系统等,正日益广泛应用于深水油气的勘探开发中。我国深水区为浅水区的延伸,与已取得众多成功发现的浅水区油气地质条件相似,油气成藏条件优越,配套良好,具有良好的油气前景,最新的荔湾3-1-1井取得的重大发现亦证实了此点,因此,应加快勘探开发的步伐,充分利用深水区丰富的油气资源。Deepwater area has currently become one of the most popular domains of exploration for oil and gas for its abundant oil and gas resources. The production of deepwater oil and gas and its proportion in offshore oil and gas rises continually. For example, the production of deepwater oil and gas increased to 1.4 billion barrels in 2005 rising from less than 0.2 billion barrels in 1996. It accounted for 10% and 7% in offshore oil and gas production in 2004, which will rise to 25% and 12% in 2005. Deepwater exploration is currently the most successful and most profitable domain. However, along with the development of deepwater exploration, it will face up much more difficulties, such as smaller size of reservoir, more complicated reservoir fluid, worse marine operation, and higher requirement for techniques. To solve these problems, many advanced technologies are widely applied, including high-resolution 3D seismic technology, 4C/4D seismic technology, drilling technology of horizontal wells and extended reach wells, intellectual completion technology, various types of deepwater operating platforms, and more autonomous submarine production systems. The deep area is the extension of shallow water area in China, so it has some oil and gas geological conditions similar to the shallow water area. Deepwater area in China has favorable conditions for oil and gas accumulation and broad prospect for oil and gas exploration, which has been proved by the up-to-date discovery made in Lizhiwan3-1-1. Therefore, it is urgent to accelerate exploration and development in deepwater area and make full use of the rich oil and resources there.
