摘　　要：胜利油田低渗透油藏资源丰富,已探明石油地质储量达11.8×10^(8)t,具有良好的开发前景。但低渗透油藏由于具有孔隙度低、储层非均质性强和渗流能力差的特点,在开发过程中存在“注不进、采不出”的问题。为实现低渗透油藏高效开发,系统梳理了胜利油田低渗透油藏储层预测分析方法以及高效开发技术,并结合现有技术的优缺点对低渗透油藏开发技术方向进行展望。通过研究与实践得到:①胜利油田通过攻关,研究形成了储层预测、地应力预测以及储层非均质性评价等精细油藏描述技术。②通过理论技术创新,不断突破储量动用物性下限,攻关形成了特低渗透油藏仿水平井注水开发技术、致密油藏长井段多级压裂水平井开发技术、一般低渗透油藏井网适配提高采收率技术、低渗透-致密油藏压驱开发技术和增黏型乳液-表面活性剂驱开发技术等差异开发技术系列,取得了良好的开发效果。③结合胜利油田低渗透油藏高质量发展及提速提效开发的实际需求,提出了双控转流线井网重构技术、CCUS技术和纳米气泡水驱技术,为低渗透油藏提高采收率指明发展方向。Shengli Oilfield has abundant low-permeability oil reservoirs with proven reserves of 1.18 billion tons,presenting a good prospect for development.However,there is a problem of inability to inject and produce during the development process of the oil reservoirs due to the low porosity,poor permeability,and strong heterogeneity of the low-permeability oil reservoir.A systematic review was conducted on the prediction and analysis methods for low-permeability oil reservoirs in Shengli Oilfield to achieve effi-cient development of low-permeability oil reservoirs,as well as efficient development technologies,and the advantages and disad-vantages of existing technologies were analyzed to provide an outlook for the development technologies of low-permeability oil res-ervoirs.Based on research and practice,the following conclusions are drawn:①Shengli Oilfield has developed fine reservoir char-acterization technologies such as reservoir prediction,in-situ stress prediction,and evaluation of reservoir heterogeneity.②Based on theoretical and technological innovation,the physical limit of reserve production was constantly broken,forming differential de-velopment technology series,such as water injection development technology of horizontal wells in ultra-low permeability oil reser-voirs,long well section multi-stage fracturing development technology of horizontal wells in tight oil reservoirs,well pattern adap-tation technology for enhanced oil recovery of general low-permeability oil reservoirs,pressure flooding technology in low-permeability tight oil reservoirs,and viscous emulsion-surfactant flooding technology.Good development results have been achieved.③Combined with the actual needs of high-quality development and speed and efficiency improvement development of low-permeability oil reservoirs in Shengli Oilfield,the well pattern reconstruction technology of dual control streamline variation,CCUS technology,and nanobubble flooding technology were proposed,pointing out the development direction for improving oil r
