本文给出了考虑续流影响的理论模型，并利用拉普拉斯积分变换得到拉氏空间无量纲井底压力解，可以准确地解释有续流影响的测试资料获得地层及井筒的有关参数。
In this paper, the theoretical model considering the effect of freewheeling is given. The dimensionless bottom hole pressure solution in Laplace space is obtained by Laplace integral transform, and the relevant parameters of formation and wellbore can be accurately explained by the test data with influence of freewheeling.
