摘    要:压裂水平井是开发低渗透油藏的重要技术之一。压裂水平井的产能预测是压裂水平井优化设计、取得较好开发效果的基础。考虑启动压力梯度,建立了压裂水平井的产能预测公式,分析了启动压力梯度、裂缝条数对压裂水平井产能的影响。与文献中的压裂水平井产能公式对比具有较高的精度。对低渗透油藏压裂水平井的优化设计具有重要的指导意义。

关 键 词:低渗透油藏  压裂水平井  产能预测  启动压力梯度

Abstract:Fractured Horizontal Well is one of the most important techniques to develop low Permeability reservoirs. The productivity prediction of fractured horizontal well is the base of optimal design. In this paper, according to the characteristic of low permeability reservoir, the steady flow productivity prediction formula of fractured horizontal well is established in which the threshold pressure gradient is taken into consideration. The effect of threshold pressure gradient and the fracture number on the productivity is analyzed. And the productivity equation from this paper is compared with other four different formula. The research result is instructive for the development of horizontal well in low permeability reservoirs.
Keywords:Low permeability reservoir  fractured horizontal well  productivity prediction  threshold pressure gradient
