摘要: 在现代试井解释中,经常会遇到许多的试井物理模型,其中包括均质、双重介质、复合油藏等模型。应用者或软件开发者在应用时往往会根据不同的模型分别进行求解,每一种模型都要进行求解,无形中会浪费很多人力。针对三重介质复合油藏,建立了三重介质复合油藏的有效井径模型,通过拉普拉斯变换方法求出了井底压力的拉氏空间解,并且通过简化分解,将各种试井解释模型统一起来。该模型几乎包含了所有的试井解释模型(水平井除外),对应用者特别适用。

Abstract: In well test analysis, many well test physical models are often used, including homogeneous, dual-media, composite reservoir model etc. User or software development engineer used to separately solve each practical problem based on different models, but the efficiency was very low. Aiming at ternary media composite reservoir, the effective well-radius model of the ternary media, composite reservoir was established in the paper. The Laplace solution under bottom-hole pressure was obtained with the Laplace transformation, and then the well test interpretation model was unified through simplifying and decomposing. The model almost included all the models in well test interpretation (except for the horizontal well).

Key words: model, well test interpretation, bottom hole pressure
