摘　　要：分析外围中小盆地近几年勘探进展并取得4点启示：近几年勘探成效超过预期，外围盆地有望成为现实的增储领域；生油凹陷的深陷带是最有利的勘探区域；能否发现大中型油气田是盆地迎来勘探高峰和勘探可持续发展的关键；科技进步是实现勘探突破的重要保证。依据8个勘探程度相对较高的中小盆地21个凹陷的最大油藏规模与凹陷资源丰度、资源规模关系探索建立了外围盆地评价优选标准，并针对中石油21个外围盆地开展了评价优选和勘探潜力分析，确定了6个Ⅰ类盆地和8个Ⅱ类盆地勘探前景可观。在此基础上，开展了外围中小盆地发展战略研究，并提出了将勘探重点由构造高部位转向凹陷深陷区和分4个层次开展部署的勘探建议。This paper draws inspiration from analyzing the exploration progress in mid-small sized peripheral basins in recent years： firstly, the exploration results obtained have exceeded what expected, and peripheral basins are expected to turn into tangible domains for increasing reserves; secondly, deeply trapped petroleum generative sags are the most favorable exploration areas; thirdly, whether to discover large and medium sized oil and gas fields is critical to realize exploration peak and sustainable development; fourthly, technological progress assures the achievement of exploration breakthroughs importantly. On the basis of correlation of the maximum reservoir size and the resource abundance and scale of 21 sags of 8 mid-small sized basins with higher exploration degree, this paper sets the evaluating selection criteria of peripheral basins, carries on evaluating selection and exploration potential analysis of PetroChina＇s 21 peripheral basins, and confirms 6 Class-I basins and 8 Class-II basins with broad exploration prospect. On that basis, this paper conducts study on development strategy of mid-small sized peripheral basins, and proposes that exploration turn into deeply trapped sags from high structures at four levels.
