摘　　要：鄂尔多斯盆地东部榆林、子洲气田已建成生产能力68亿立方米/年,已稳产8.4年,收到良好的开发效果,实现气田持续稳产成为当前研究的核心问题。通过划分开发单元,建立气藏精细调控体系,气田地层压力下降平稳,年压降1.0 MPa,整体山2气藏稳产形势良好;动态评价与相控建模相结合,落实气藏加密潜力,通过对山2气藏井网完善加密调整可建产能2.2亿立方米,气藏未动用储量精细刻画结合经济评价,可建产能3.8亿立方米;通过多因素优化,评价气藏增压调整潜力,可将稳产期延长2年。综合以上稳产措施,盆地东部山2气藏68亿立方米规模可持续稳产至2020年,效果显著。The production capacity of 6.8 billion cubic meters per year has been built in Yulin,Zizhou gas field of the eastern Erdos basin, having been steadily producing for 8.4 years, received good development effect.Realizing the sustained and stable production of the gas field becomes the core issue of the current study.By dividing the development unit and the establishment of gas reservoir fine regulation system,the formation pressure of gas field steadily declines, the pressure drop of 1.0 Mpa per year,and the stable production situation is good for the whole Shan2 reservoir.Combined the dynamic evaluation and facies controlledmodeling,the gas reservoir encryption potential is implemented.Perfecting Shan2 gas reservoir well network encryption can adjust the construction of production capacity of 0.22 billion cubic meters per year.Through gas reservoir fine description of unused reserves combined with economic evaluation, the production capacity of 0.38 billion cubic meters per year can be built.Through multi factor optimization and the gas boosting adjustment potential evaluating, the stable production period can be extended for 2 years.Integrated above measures, the production scale of 6.8 billion cubic meters per year for Shan2 reservoir in the east of the Ordos basin can achieve sustainable and stable production to 2020 and the development effect is remarkable.
