This paper presents a well test interpretation methodology using characteristic points and lines found on the pressure and pressure derivative versus time log–log plot for the characterization of a finite-conductivity fractured vertical hydrocarbon well in a double-porosity (heterogeneous) formation considering a new and practical analytical Laplacian model which require less computational time and have more accuracy than semi-analytical models. Some existing equations are found to work well for the new model, and new expressions are developed. The accuracy of the developed equations is successfully tested with synthetical examples.

天然裂缝油气层中有限电导率水力压裂直井试压的实用解释

本文介绍了一种试井解释方法，该方法使用压力和压力导数与时间对数-对数图上的特征点和线，用于表征双孔隙（非均质）地层中的有限电导裂缝垂直油气井，并考虑新的和实用的分析拉普拉斯模型，比半分析模型需要更少的计算时间和更高的精度。发现一些现有方程适用于新模型，并开发了新表达式。用综合实例成功地测试了所开发方程的准确性。
