【Abstract】 By application of the technology of pulse well testing, this paper determined the parameters of two layer infinity homogeneous reservoir. The ratio of formation coefficients and the ratio of coefficients of pressure derivative were used to match two layer flow rate. Analytic solution to integrated pressure at the observed well was achieved by using the principle of pressure superposition. The type curve of secant method was plotted. A practical method was provided in order to describe accurately layered reservoirs and interpret plane heterogeneous of reservoirs.更多还原
