摘　　要：凝析气藏水平井产能预测与评价是水平井设计中的一个重要方面。水平井产能的影响因素较多,已有的水平井产能计算方法,其理论计算结果与实际生产数据往往差别较大。本文建立了一种凝析气藏水平井产能评价的新方法,该方法把理论计算公式和现场实际的直井生产试井资料相结合,利用直井试井解释结果,可以对开发设计水平井的产能进行相对精确地预测和比较切合实际地评价,从而为水平井的设计提供依据,并给出了实例计算。Horizontal well productivity predication and evaluation are important issues at its design stage for a gas condensate reservoir.Theoretical formulae available cannot satisfy the production practice,due to many factors involved in horizontal well potential.In combination with theoretical formula and well testing interpretation data of vertical well,a new method of horizontal well productivity evaluation for a gas condensate reservoir is established,and therefore,relatively accurate prediction and evaluation can be achieved.A calculation example is given,which demonstrates how the theory can provide a basic instruction for horizontal well evaluation.
