Saphir和Topaze软件在水平井压裂评价中的对比和应用

Comparison and Application of Saphir and Topaze in the Evaluation of Horizontal Well Fracturing

文章应用Topaze生产分析软件和Saphir试井解释软件对压裂水平井进行动态分析和试井解释,获取相关的储层参数,包括表皮系数、裂缝半长、有效渗透率等,并将两种软件解释出的参数进行对比,通过实例分析,给出了两种软件在压裂水平井动态参数解释中的适用条件。

With the methods of Saphir and Topaze, we obtained the relevant parameters of fracturing horizontal wells by dynamic analyses and well test interpretations, including skin factor, fracture half - length, effective permeability and so on. We contrasted the parameters derived from the two methods. Combining instance analysises, we worked out the application conditions for the interpretation of dynamic parameters in fracturing horizontal wells of the two methods.
