摘　　要：水平井是获得气田高产的主要技术途径，靖边气田储层渗透率低、层薄、非均质性强，此类气藏水平井开发的适应性及影响气井产能的关键因素成为开发过程中需要解决的主要问题。在广泛调研水平井产能评价方法的基础上，利用Joshi理论模型研究了渗透率、有效厚度、水平段长度、储层伤害等各种因素对靖边气田水平气井产能的影响，并结合靖边气田地质特征分析了各参数的敏感性，确定了该类储层水平井产能的主控因素。从而为气田水平气井地质设计、钻井工程及气藏工程研究提供了较为科学的依据。On the basis of extensive investigation of evaluation methods of horizontal well producion capacity, the impact of permeability, effective thickness, horizontal length, reservoir damage and other factors on the productivity of horizontal gas wells of Jingbian gasfield has been studied by using Joshi theoretical models. In conjunction with geological characteristics of Jingbian gasfield, the sensitivity of each parameter has been analyzed, and main controlling factors of horizontal well production capacity of various reservoirs have been determined. ~nd thus they provide a more scientific basis for geological design, drilling engineering and gas reservoir engineering studies of horizontal wells in a gasfield.
