摘要
本文较全面地分析了非稳定井流中有代表性的承压、半承压及无压井流和产生似稳定的条件。从渗流的特点出发,对稳定井流与非稳定井流似稳定阶段中各要素的特征进行了对比,找出相似之处。探讨了行之有效的稳定流理论及相应公式扩大其使用范围的可能性。
The typic unsteady well flows and the conditions to produce the approximating steady stage were analysed. The similar parts had been found through the comparing of the characteristic of each factors in the steady well flow. The formula of steady well flow could be used in unsteady flow The possibilities to expand the usage of steady flow theory and its formulas were studied.
