【Abstract】 This paper revise the formula presented and deduce a new formula on productivity forecast of fractured horizontal well,applying potential function principles,superposition principle,and mathematical method for solving matrix,considering flow resistance and pressure drop in fracture.As an example,the productivity of fractured horizontal well in a low permeability gas reservoir has been tested by using this formula,and some useful conclusions have been drawn from comparing and analyzing some factors.These conclusions are instructive in designing fractured horizontal well for low permeability reservoir.更多还原
