根据水平气井横向缝压裂的多相流体渗流机理,结合气藏气水两相渗流的达西定律以及物质平衡原理,建立了水平气井横向缝压裂三维两相产能模拟模型,并根据建立的模拟模型编制了计算程序.通过进行实例计算 ,初步得到了裂缝及储层参数对压后产能的影响结果.实际结果表明:该模型能够描述具有多条横向缝的压裂水平气井的生产特征,对水平气井横向缝压裂产能模拟有广泛的适应性 ,具有较强的应用性和使用价值.

This paper set up a three-dimensional two-phase productivity simulation model of transverse crack frac-turing of horizontal gas wells based on its multi-phase fluid percolation mechanism ,Darcy's law of gas-water two-phase percolation and material balance theory ,and established the calculation program on the basis of the model . The practical calculation obtained the result of how the crack and reservoir parameter influence fractured productivi-ty .The model can be used to describe production characteristics of horizontal wells with multiple transverse cracks fracturing and is adaptive to productivity simulation of transverse crack fracturing of horizontal gas wells .
