摘　　要：近年来,通过持续深化勘探,在我国东部陆上断陷盆地成熟探区实现了效益增储,并在新区带、新类型、新层系上不断有新的发现与拓展,页岩油正成为战略接替资源,但也面临着具有引领意义的发现少、发现后规模展开难度大、对关键勘探技术支撑的依赖显著增加、资源品质下降、勘探成效下降的高质量勘探压力。通过系统剖析中国石油化工股份有限公司(简称中国石化)所辖东部断陷盆地成熟探区勘探发展形势与勘探潜力,明确了勘探转型发展的主要方向及举措。中国石化东部断陷盆地成熟探区具有石油勘探发展的资源优势、理论技术优势,是持续增储的“压舱石”。勘探工作必须正视勘探的阶段性、长期性、多资源并存的客观特点,树立富油气盆地勘探无禁区的理念,解放思想、创新思路,以实现高质量发展。统筹协调常规与非常规、精细勘探与规模拓展勘探、地震部署与提效勘探、工程技术与突破转化等关系是勘探转型发展的主要方向;持续优化常规与非常规差异化部署、提升高精度高密度地震勘探、突出剩余油气资源潜力评价、优化“三新”领域突破部署和一体化评价是勘探转型发展的主要举措;加强勘探基础工作、勘探技术迭代升级和勘探开发一体化组织运行是实现高质量勘探的主要手段。In recent years,the continuous exploration progress in mature areas in continental fault basins in eastern China enables to achieve the benefit reserve increase and obtain discoveries and expansion in new exploration zones,new resource types and new series,and shale oil is growing to be the strategic replacement resources.However,the high-quality exploration also faces some challenges,such as few discoveries with leading significance,great difficulty in large-scale development after obtaining discovery,significant increase in dependence on key exploration support technologies,deterioration in resource quality,and decrease in exploration benefits.By systematically analyzing the exploration situation and potential in mature areas in eastern fault basins of Sinopec,the main direction and countermeasures of exploration transformation and development are clarified.The mature exploration areas in eastern fault basins of Sinopec have resource,theoretical and technological advantages,which is a“ballast stone”for continuous reserve increase.In the exploration work,the objective characteristics of multi-stage and long-term exploration,and coexistence of multi-type resources should be emphasized,and the concept of“no forbidden exploration field”in oil and gas rich basins should be establish to liberate the mind and innovate ideas,so as to achieve the high-quality development.The main direction of exploration transformation and development should be followed to coordinate the relationship between conventional and unconventional resources,fine exploration and large-scale expansion,seismic deployment and high-efficiency exploration,technological breakthrough and achievements transformation;The main countermeasures include the continuous optimization of differentiated deployment in conventional and unconventional resources,improvement in high-precision and high-density seismic exploration,emphasis on the evaluation of remaining oil and gas resources,deployment optimization in“three new”fields,and integrated evaluati
