Abstract: The annual oil reserves and oil production proven in east China account for 75% and 90% of the total amounts of the China National Petrochemical Corporation (SINOPEC) respectively.As the exploration maturity-recovery ratio of reserves increase continuously,it is more difficult to maintain the stable production in old oil fields.The recent study shows that there still have greater remaining oil resources and broad remaining exploration space in the eastern matured oil areas.Un-equilibrium exploration maturity and the multiple exploration objective formations showed a great exploration domain in this area.The inherit regularity of formation and accumulation in multiple oil and gas fields leads to a prolonged process of reserve growth.Application of new exploration ideas,new theory and technologies,and detailed geology research will promote the continuous and stable development of oil and gas exploration,wide exploration realm and great resource potential in eastern new exploration areas.The eastern exploration region in China is still the major area of oil production and reserve additions of the SINOPEC during the Tenth and Eleventh Five-Year Plan period.

Key words: exploration region of east China, oil and gas resources, exploration potential, oil reserves, oil production

摘要： 东部探区是中国石油化工集团公司(中国石化)目前储量和产量的主要集中地区,年度探明石油地质储量占中国石化当年探明储量的3/4,石油年产量占中国石化去年产量的90%。随着勘探程度和地下原油采出程度的不断提高,老油田稳产的难度越来越大。近年来的科技攻关表明,东部探区仍然有较大的资源潜力和广阔的勘探空间。同时,东部陆相盆地复式油气聚集成藏的内在规律决定该区储量增长是一个长期过程,而新理论、新技术的完善和应用将进一步挖掘勘探潜力。因此,东部探区仍然是中国石化“十五”乃至“十一五”期间增储、稳产的主战场
