摘　　要：渤海油田历经40余年的勘探开发建设,于2021年成功建成我国第一大原油生产基地,常规勘探-开发接力模式已无法满足储量和产量增长的要求。在勘探开发一体化大背景下,针对勘探工作,以渤海南部区域为例,首先厘清南部资源潜力,对南部剩余未钻潜力目标进行统计与梳理,并根据其分布圈定有利区带;在此基础上,借鉴风险勘探目标评价标准,增加资源规模及油品性质双因素,对潜力区带进行量化分级,得到潜力区带的排序,指导下一步的勘探方向。通过潜力区带量化分级,已形成渤西南油气第二增长建设方案及渤中26-F油气中心整体建设方案,证明该量化分级方法具有一定的可行性,不仅为勘探开发一体化链条中的钻完井工程奠定了基础,亦可为其他海域的勘探开发一体化工作提供参考。After over 40 years of exploration and development,the Bohai Oilfield successfully established China′s largest crude oil production base in 2021.The conventional exploration-development relay model can no longer meet the requirements for reserves and production growth.In the context of integrated exploration and development,this study focuses on exploration efforts in the southern Bohai Sea region.It first clarifies the resource potential in the southern area,statistically organizing and identifying remaining undrilled potential targets and delineating favorable exploration zones based on their distribution.Building on this,a risk evaluation standard for exploration targets is adopted,incorporating both resource scale and oil quality as dual factors to quantitatively classify the potential exploration zones,resulting in a ranked order to guide subsequent exploration directions.Based on this quantitative classification of potential exploration zones,the paper has developed the second growth construction plan for the southwest Bohai and the overall construction plan for the 26-F oil and gas center in the Bohai Central area.This method of quantitative classification demonstrates feasibility,laying a foundation for the drilling and completion engineering within the integrated exploration and development chain,and providing a reference for integrated exploration and development efforts in other maritime regions.
