Keyword:  鄂尔多斯盆地东部山2气藏稳产措施精细调控内部挖潜增压开采;
Abstract: 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.
