摘　　要：以苏里格气田水平井为例,根据水平气井产能方程和气水垂直管流Hagedorn-Brown模型,研究水平气井气层有效厚度、各向异性、地层压力及水平井段长度等因素对产能的影响。应用节点分析理论,绘出不同情况下水平气井流入、流出动态曲线。According to the deliverability equation of horizontal wells and Hagedorn-Brown model of pipe flow in vertical direction,based on Sulige gas oilfield,parameters including reservoir bed thickness,its anisotropism,reservoir pressure and horizontal length are discussed.IPR curves and out performance curves of horizontal wells are obtained in different conditions by theory of nodal analysis.Results provide important basis for determination of reasonable work system and productivity analysis.
