摘　　要：由于重力分异作用 ,对直井的解释技术通常不适用于水平井。许多水平井测井所提取的数据从常规意义上讲是难以解释的 ,因为与直井相比水平井流动状态的变化更多 ,原因是动态起伏和井眼尺寸的影响。根据水平井流动状态 ,从两相流动的动力守恒方程出发 ,建立水平井流动模型 ,对层状流、环状流及紊流 3种情况进行分析 ,求取参数。对水平井的定量解释作出一些尝试性的研究 ,提出具体解释步骤。Due to gravity function,interpretation technique in vertical wells is not fit to horizontal wells,which brings new challenges to production logging. Coventionally speaking,log data from horizontal wells are not easily interpretated because flow regimes in the horizontal wells,compared with that in the vertical wells,change more greatly due to dynamic undulations and borehole dimensions.On the basis of the predecessors' studies and two-phase flow dynamic conservation equations,horizontal flow model is set up to analyse the laminar flow, annular flow and turbulent flow, and then figure out the parameters needed. Trial research on quantitative interpretation of horizontal well logging is made and practical interpretation measures are given.
