The invention provides a heterogeneous gas reservoir development well type division method and device. The method comprises the steps that the open flow capacity and gas well dynamic reserves of heterogeneous gas reservoir development wells are calculated; and according to the open flow capacity and the gas well dynamic reserves, the heterogeneous gas reservoir development well types are divided. The production capacity of the development well can be comprehensively and systematically evaluated, the early-stage high yield and the long-term stable yield of the development gas well are improved, and therefore the development benefit of a gas reservoir is improved, and the development efficiency of the gas reservoir is achieved. 本发明提供一种非均质性气藏开发井类型划分方法及装置，方法包括：计算非均质性气藏开发井的无阻流量和气井动态储量；根据所述无阻流量和所述气井动态储量对非均质性气藏开发井类型进行划分。本发明能够较为全面和系统的评价开发井生产能力，提高开发气井早期高产和长期稳产，从而提高气藏的开发效益，实现气藏开发效率。
