摘　　要：本文对牛２０高压低渗透低饱和岩性油藏开发过程进行较系统的分析，初步总结出低渗透油藏在特殊地质条件下开发的基本作法：油层压裂改造；依据地层裂缝方向布署注采井网；适时选择注水时机，及时补充地层能量；采用高压注水，水质精细过滤，密闭输送工艺配套，注水量保持长期稳定。并取得较好的开发效果。This paper gives the cornprehcnsive analysis for the process of developnient of pres- sure,low permeability and low saturation prcassure lithologic oil raservoir.It summarizes the methodfor the low permeability oil reservoir according to its special geologic characteristics such as well stimu- lation,arranging tlie well pattern in accordance with the direction of formation fracture, selecting thewater injection time,pressure maintenance,injecting water under high prassure, fine filtration of wa-ter,technology of sealing transportation and keeping water injection stable for a long time,It get abetter reeult of development.
