摘　　要：低渗透油藏是未来石油勘探开发的主要对象,保有未动用储量经过多轮次筛选后,剩余储量品位差,因此开发技术的适用条件是油藏能否动用的关键因素。该文以中国石化低渗透油藏为例,研究了“十二五”以来不同渗透率级别的低渗透油藏探明未开发储量的开发技术现状及动用条件,分析了保有未动用评价储量的分类,结合现有难动用储量类型和技术发展趋势,进一步厘清了低渗透油藏未来技术需求和攻关方向。Reservoir with low-permeability is the future object of oil exploration and development.After multiple rounds of screening,the remaining reserves have poor grade.Therefore,the applicable conditions of development technology are the key factors for whether the reservoir can be produced.Taking SINOPEC low-permeability reservoirs as an example,it is discussed in this paper for the status of development technology and production conditions of proved undeveloped reserves in low-permeability reservoirs with different permeability levels since the 12th Five-Year Plan.Moreover,the classification of development potential of undeveloped reserves was carried out.Combined with the existing types of hard-to-develop reserves and technological development trends,the future technical requirements and research directions of low-permeability reservoirs were further clarified.
