Abstract
This paper presents a new percolation method that is power-law non-linear percolation pattern in low-permeability reservoirs. Well test interpretation model on power-law non-linear percolation pattern is given and the way how to solve those equations is provided. To analyze and compare well test interpretation models of four different percolation pattern. The balance factor of power-law percolation pattern responds little to pressure and the power-law index responds greatly to pressure yet. Models were used to oil field can those results to be achieved that, new established model presents type curves are more gently and less than that obtains from the method of start-up pressure gradient. Also, this non-linear effect measure makes derivative of pressure curve less and more early time than that gets from the closed boundary effect and there are be obviously distinction. This study addresses type curves capable of analyzing field cases and offers more logical and reliable results.
