PEBI meshing method of numerical well tests for horizontal wells was researched, while the flow equation of infinite conductivity and uniform flux horizontal wells was derived. By regarding the horizontal well as the internal boundary, an internal boundary model for horizontal wells was proposed, which could avoid the influence of variant well grid scales on the calculation precision of the early flow period in the Peaceman model. An example was calculated with the model, whose results were compared with the analytical and numerical results of Eclipse Weltest software. The comparison indicates that the result of internal boundary infinite conductivity model is between Weltest analytical and numerical results, while the uniform flux model result accords with the analytical result in the middle-and-final period.
