摘要: 自喷井流压上升的测试资料解释方法与软件在国内外是空白,针对这一情况,建立了变表皮系数、变形双孔介质、高速非达西渗流的数学模型与数值模型,并研制了解释评价软件,它可解释其它试井分析软件不能解释的自喷井流动期井底压力上升的测试资料,且能得到随时间变化的表皮系数及气井的真实绝对无阻流量。应用表明,所介绍的方法不仅具有可行性,且解释结果也比较符合实际。

Abstract: The interpretation technique and software about flowing well testing data with downhole flow pressure rising are completely blanks at home and abroad. For this reason, the mathematical and numerical models with variable skin factor,deformed dual porosity and high velocity non-Darcy flow are established, and the software for interpretation and evaluation of them is developed, which can be used to in-terpret flowing well testing data with downhole flow pressure rising that is impossibly interpreted by other well test analysis software. The skin factor and real absolute open flow vs. time in a gas well can also be obtained. Practical application shows that the method or software presented in this paper is not only of feasibility, but the interpreted results are close to real conditions.

Key words: flowing well, flowing pressure, well test interpretation, skin factor, productivity evaluation
