摘要
文章分别用已建立的气水两相地层 /井筒两相组合数值模型、常规试井方法和SimBestⅡ数模软件对二口实际气水井的压力恢复数据进行了解释 ,分析表明 :建立的气水井组合数值模型比目前常规的单相气井试井模型具有明显的优势 ,解释结果更可靠、更丰富。同时 ,数值方法的离散化特点也便于独立地对地层中各节点相关参数进行调整 。
In the papre, a gas-water two-phase well-bore/reservoir assemblage testing numerical model is presented and the practical pressure build-up data of two wells are interpreted by use of this model, conventional well test method and Sim-Best II numerical simulation software respectively. Through analyzing it is indicated that the gas-water wellbore/ reservoir assemblage numerical model set up by the authors has obvious advantage over the conventional single-phase gas well test model used at present and the results interpreted by this numerical model are more reliable and more wealthy. Meanwhile the relevant parameters at each node point in the formation can be conveniently and independently regulated by use of the discretization character of numerical method, thus causing the gas-water well testing analysis of complex formation to be really realized.
