摘　　要：在气藏开发方案设计中,气井合理产能是气藏经济开采的重要依据。新滩油田垦东34块馆陶组上段气顶油藏位于胜利油区极浅海水域,矿场无稳定试井资料。为了确定气井合理产能,采用经济极限初产、临界携液产量、绝对无阻流量和数值模拟方法进行了优化研究。结果表明,气井合理产能控制在1.5×104m3/d,可实现气井在不出砂条件下长期稳产,并能提高气顶油藏开发效果。方案实施后气井生产效果理想,为无稳定试井资料条件下确定气井合理产能提供了一套可行的方法。Determination of rational productivity of the gas well is one of the important foundations of gas reservoir economic development during the development project planning. Upper Guantao gas - cap reservoir of Kendong34 block lies in extreme shallow sea area of Shengli petroliferous province, and no stable field well testing information. Several research methods, such as e-conomic limit initial productivity, critical liquid - carrying capacity , absolute open - flow capacity and numerical simulation , are applied to optimize and determine the rational productivity of gas well. The research indicates that long - term and stable production would be obtained without sand production in the gas well,and the development results of the gas -cap reservoir would be enhanced under the condition of 1.5 × 104m3/d of the rational productivity. The productivity of gas wells is ideal after putting into production of the projects. The research provides a set of available methods for determining the productivity of gas well for lack of stable well testing data.
