中国石油海外“十三五”油气勘探重大成果与前景展望

Major achievements of CNPC overseas oil and gas exploration during the 13th Five-Year Plan and its prospects

“十三五”以来,国际油价持续低迷、外部投资环境日益复杂,如何尽快适应复杂的内外部环境、实现精准部署与效益勘探是中国石油天然气集团有限公司(简称中国石油)海外油气勘探面临的重大问题。中国石油海外油气勘探提出了以效益为中心,积极寻求规模优质可快速动用储量,大力实施风险勘探和精细勘探的部署策略。创新实施“产学研用”一体化科研攻关组织模式、优化总部决策流程、坚持勘探开发工程一体化、加强深水勘探领域国际合作、立足全球大盆地积极开拓勘探新项目,逐步积累形成了一系列行之有效的勘探管理措施。2016—2019年,通过上述部署和措施的实施,中国石油海外油气勘探取得12项重大突破与战略新发现,成熟探区精细勘探多点开花,累计探明油气地质储量超10×10^8t油当量,桶油发现成本低于2美元,平均探井成功率为76%。当前中国石油海外油气勘探虽然面临国际油价持续低位、勘探项目急剧减少、新区块获取竞争日益激烈、常规油气资源品质劣质化、勘探对象愈加复杂、深水油气独立勘探开发能力弱等挑战,但全球待发现油气资源依然丰富,高新技术跨界融合必将推动勘探理念的转变和技术的革新,海外油气勘探前景广阔。

Since the 13th Five-Year Plan,the oil price has continuously remained low and the global investment environment has become increasingly complicated.How to adapt to the complicated internal and external environments as soon as possible,and to achieve accurate deployment and benefit exploration is a major issue faced by CNPC overseas oil and gas exploration.The company has put forward the deployment strategy of focusing on benefi ts,actively discovering large-scale,high-quality and rapidly-recoverable reserves,and vigorously carrying out risk exploration and fine exploration.A series of effective exploration management measures have been gradually formed,including innovating and implementing the integrated research organization mode of“industry-college-institute-application cooperation”,optimizing the decision-making process of the headquarters,adhering to the integration of exploration-development-engineering,strengthening international cooperation in deep-water exploration,and actively exploring new exploration projects based on screening of the global large basins.In 2016-2019,through the implementation of the above deployment and measures,CNPC overseas oil and gas exploration has made 12 major breakthroughs and strategic discoveries.In mature exploration areas,fi ndings have been achieved in several exploration fi elds through fi ne exploration.The cumulative proven oil and gas geological reserves are more than 10×10^8t oil equivalent,the discovery cost per barrel oil is less than$2,and the average success rate of exploration well is 76%.At present,CNPC overseas oil and gas exploration is still facing challenges such as the continuous low international oil price,the sharp decrease of exploration projects,the increasingly fi erce competition for new blocks,the inferior quality of conventional oil and gas resources,the increasingly complex exploration objects,and the weak capacity of independent exploration and development of deep-water oil and gas.But the undiscovered oil and gas resources are still rich in the world.The cross-border integration of advanced technologies will certainly promote the transformation of exploration concepts and innovation of technologies,and so the prospects of overseas oil and gas exploration are broad.
