摘要
在系统梳理中国石油化工股份有限公司(简称中国石化)“十四五”以来高质量勘探举措、理论技术进展及油气勘探成果的基础上,提出了油气勘探发展战略。“十四五”以来,中国石化坚定资源发展信心,大力推动高质量勘探实践,在塔里木、四川、渤海湾、准噶尔、鄂尔多斯等盆地的深层碳酸盐岩、陆相页岩油、深层页岩气、中西部碎屑岩、成熟探区隐蔽油气藏、深层煤层气等领域取得了主要勘探成果,为石油稳增长、天然气快上产夯实了储量基础。同时,发展完善了超深走滑断控缝洞型油气成藏理论、创新形成了页岩油成储成烃富集理论、深化了海相页岩气“二元富集”与致密碎屑岩油气差异富集机理认识等;攻关形成了复杂地质结构与储层结构条件下的以地震勘探、深层—超深层钻完井、超深层测录试井、水平井压裂技术等为代表的关键技术与工程工艺技术。展望未来,中国石化探区具备石油稳定发展、天然气快速发展的资源基础,勘探工作聚焦保拓矿权、勘探突破、规模增储三大核心责任,以深地工程、页岩油气示范工程、致密碎屑岩效益攻坚、常非统筹为统领,加快推进战略突破发现,落实规模增储阵地,进一步夯实上游可持续发展资源基础。
A systematic review is conducted on the high-quality exploration activities,theoretical and technological progress,and exploration achievements of Sinopec during the 14th Five-Year Plan period,and a development strategy is proposed for the future petroleum exploration.Since the 14th Five-Year Plan period,Sinopec has strengthened its confidence in resource development and vigorously promoted highquality exploration practices,which support to make significant exploration achievements in fields such as deep carbonate rocks,continental shale oil,deep shale gas,clastic rocks in western regions,subtle oil and gas reservoirs in mature exploration areas,and deep CBM in Tarim,Sichuan,Bohai Bay,Junggar,and Ordos basins,solidifying reserve basis for stable oil output growth and rapid gas output growth.In addition,significant progress has been made in the development and improvement of deep strike-slip fault-controlled fracture-cavity type hydrocarbon accumulation theory,the innovative shale oil reservoir formation,hydrocarbon accumulation and enrichment theory,and the deep understanding of“dual enrichment”of marine shale gas and differential enrichment mechanisms of oil and gas reservoirs in tight clastic rocks.Furthermore,the key exploration and engineering technologies for targets with complex geological and reservoir structural conditions,represented by seismic exploration,well drilling and completion in deep to ultra-deep formations,wireline logging,mud logging and well testing in ultra-deep formation,and horizontal well fracturing,have been researched and developed.Looking ahead,Sinopec has a solid resource foundation in its exploration areas for achieving steady oil output and rapid increase in gas production.The exploration work will focus on three core responsibilities of securing and expanding mining rights areas,achieving exploration breakthroughs,and increasing reserves and resources on a large scale.Guided by deep earth engineering,shale oil and gas demonstration projects,benefit development of tight clastic rock oil and gas reservoirs,and coordination of conventional and unconventional resources,efforts will be strengthened to accelerate the strategic breakthroughs,and establish large-scale reserve increase bases,so as to further consolidate resource foundation for the sustainable development of the upstream.
