摘要: 在前人研究的基础上,应用复位势理论、叠加原理和矩阵方程的数值分析求解方法,并考虑裂缝内的渗流阻力及压力损失,对压裂水平井产能预测公式进行了重新推导和修正,使计算结果更加合理和符合实际;利用所推导的计算公式,结合我国一实际的低渗透气田,对影响压裂水平井产能的几个重要因素进行了对比和分析,并得出有益的结论,其结果对实际低渗透油气田压裂水平井的设计具有一定的指导意义.

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.

Key words: low permeability, horizontal well, fracture, productivity forecast, flow resistance
