摘　　要：过去10年,全球油气勘探经历了油价两次断崖式下跌和“碳中和”的双重考验,勘探投资不断降低;同时随着深水油气地质理论和勘探技术的持续进步,勘探效率大幅提升。在此基础上,全球油气勘探呈现出5个显著特点:(1)油气发现个数持续减少,但平均规模不断增加;(2)天然气新发现持续维持在六成以上的较高水平,成为重要的储量增长点;(3)深水/超深水成为最为重要的增储阵地,不断揭示多个勘探新领域;(4)新发现由中浅层逐渐向深层/超深层转移,海域、陆域均有新突破;(5)巨型油气田发现维持在相对较高水平。58%的油气勘探新发现来自前沿和新兴领域的风险勘探,42%的新增储量来自成熟盆地的滚动勘探。全球油气勘探程度仍处于中低水平,未来勘探潜力可期;前沿领域是勘探的重点,应超前布局;深水、深层、天然气领域是未来的重要发展方向。同时指出俄罗斯北极、索马里海域、加勒比海周缘等十大领域值得重点关注。In the past 10 years,global oil and gas exploration experienced the double test of twice sharp falls of oil prices and“carbon neutralization”,and the exploration investment was continuously reduced;Meanwhile,the continuous development of oil and gas geological theory and exploration technology resulted in the great improvement of exploration efficiency.As a whole,global oil and gas exploration shows five remarkable characteristics:(1)The number of oil and gas discoveries has been decreasing,but the average size continuously been increasing;(2)The new discovery of natural gas has been maintained at a high level of more than 60%,growing to be a major direction of reserve growth;(3)Deep water/ultra-deep water has become the most important areas for increasing reserves,and multiple new exploration areas have been identified;(4)The new discoveries have gradually shifted from the middle-shallow formation to the deep/ultra-deep formation,and new breakthroughs have been made in the offshore area and onshore area;(5)The discoveries of giant oil and gas fields have remained at a relatively high level.The new discoveries from venture exploration in frontier areas contribute 58%of the total oil and gas discoveries,and the new reserves from rolling exploration in mature basins contribute 42%of the total reserve volume.The maturity of global oil and gas exploration is still at a medium-low level,and the exploration potential is great in the future;The frontier region is the main areas for oil and gas exploration,which should be deployed in advanced;Deep water,deep formation and natural gas areas are important exploration orientations in the future.Furthermore,it is suggested that 10 areas deserve special attention,such as the Russian Arctic,Somali offshore areas and the periphery of the Caribbean Sea.
