摘要
在文献[1]的基础上,提出了一种推导双重介质模型中裂缝和低渗基质之间与时间有关的形状因子的新方法,用以预测可压缩流体的产能,并可在试井解释中得到应用。在没有假设拟稳态的情况下,分别对一套、二套和三套裂缝的与时间有关的形状因子进行了推导。它既可以为可压缩流体的产能预测提供更准确的理论方法,也可为试井解释提供合适的形状因子、计算合理的窜流系数,从而为试井参数解释提供更加准确的理论依据。
Based on literature [1], a new method to derive the transfer function and time-dependent shape factor for fracture and low permeability matrix system was proposed, which can be used in predict the productivity of compressible fluid and in well testing interpretation. It can provide the accurate theatri- cal method for compressible fluid productivity prediction. It also ensure well testing with better theoretical basis through providing the proper shape factor and transfer function.
