国外深水油气勘探述评及中国深水油气勘探前景

经过近30 a的发展,深水油气勘探的水深记录被快速刷新;在深水区不断发现大油气田,油气储量、产量快速增长;深水区资金投入明显增长;世界深水区的剩余油气资源潜力巨大.深水油气勘探活动具有高成本、高技术、高风险和高回报的特点,正是由于深水油气勘探储量规模大、产能高形成的高回报特点才促使人们不断地向深水发起挑战.以地震技术和模拟技术为核心的勘探技术、钻采技术的进步和钻采设备的发展,以及开放的优惠政策等有利因素推动深水油气勘探向更深处发展.中国的深水油气领域广阔,目前现实的深水油气勘探领域--南海北部边缘深水区具有很好的基本石油地质条件和成藏条件,与国外获得巨大成功的深水油气勘探区较为类似,因此,其勘探潜力大,前景好.

Deepwater Petroleum Exploration Abroad and Deepwater Petroleum Exploration Prospect of China

Over the past thirty years,the deepwater exploration has already become a new bright-spot in the world petroleum industry.More than 60 countries are working on with deepwater petroleum E&P activity,and recording water depth for exploration drilling changes.Significant petroleum discoveries are continuously made in the deepwater realm where reserves and output increase largely;costs and expenditures on deepwater exploration grow rapidly.E&P activity in the deepwater area has the characteristics of high expenditure,high risk,high technology,and high return.It is the characteristics of high return coming from large reserve size and high productivity that push people to challenge the deepwater unceasingly.Such favorable factors,as exploration technologies around seismic technologies and modeling technologies,drilling and production technologies and facilities advancement,and favorable open policy,make E&P economic and thus accelerate deeper water exploration.In contrast,with vast acreage of deepwater area in China,the favorable exploration region at present is the deepwater area along the north margin of the South China Sea.The area forms favorite petroleum geological conditions and migration-accumulation conditions analogous as those successful deepwater exploration areas abroad.Therefore,it is a prospective and potential frontier.
