深水油气勘探开发——进展及启示

Progress and Enlightenment of Oil & Gas Exploration and Development in Deep Water

分析总结了世界深水油气勘探开发现状和深水油气资源分布特征、我国深水领域油气勘探进展以及南海北部陆坡区、南海西南海域以及东海冲绳海槽盆地的深水油气资源前景。经过近100年的发展,浅海油气勘探开发高峰期已经过去,新增储量和产量逐渐向深水转移。世界上深水油气盆地主要为滨大西洋深水盆地群、滨西太平洋深水盆地群、新特提斯构造域深水盆地群和环北极深水盆地群,各深水盆地群油气勘探程度和成果差别很大。我国的深水区资源丰富,潜力很大,然而由于技术、资金等原因,勘探程度很低。但近几年来,我国无论是深水的油气发现,或是深水勘探装备和技术,都取得了重要进展。加快深水油气勘探的步伐,对保障我国能源安全具有重要的战略意义。

The present world oil ＆ gas exploration and development situations in deep water areas and the distribution characteristics of the deep water HC resources are summarized in this paper, and the present oil ＆ gas exploration progress in China deep water areas is analyzed. In addition, the HC resource potentials in deep water areas in the continental slope area of the northern part of South China Sea, the southwest water area of South China Sea as well as the East China Sea have been discussed. After shallow water oil ＆ gas development for about 100 years, the peaks of offshore oil ＆ gas exploration and development have shifted from shallow to deep water areas, and new HC discoveries as well as offshore oil ＆ gas production have been made continuously in deep water areas in recent years. The deep water basins are distributed in four belts, including Atlantic Ocean deep water basins belt, west Pacific Ocean deep water basins belt, new Tethys deep water basins belt and around Arctic Ocean deep water basins belt. The petroleum exploration and development degree is quite different for different basins. The HC resource and potential in China deep water are abundant. But the exploration degree in these areas is still very low due to the limitations of technology and exploration investment. In recent years, great progress has been made in China not only in deepwater HC resource discovery, but also in the exploration ＆ development tech- nology and deep water equipment. It is very significant to fasten the exploration and development in China deep water area in order to guarantee the safety energy supply.
