This paper puts forward the definition of high capacity channels and discusses the geological condition, fluid condition and development factors which affect the formation the high capacity channel. By using the numerical concept model, the paper investigates the influence of layer rhythm, interlamination permeability difference, oil-water density difference, oil-water viscosity ratio and fluid production rate on high capacity channels formation. Analysis of simulation results shows the relationship between comprehensive coefficient and recovery, puts out the idea of predicting the formation of high capacity channels using comprehensive coefficient, and gives the comprehensive coefficient boundaries of the high capacity channels formation in positive rhythm and inverted rhythm reservoir respectively. Here we taking GuDong Qiquxi Ng63+4 reservoir as an example to estimate the formation of high capacity channels with comprehensive coefficient, and the result fits well with lots of information from field testing.
