摘　　要：应用复位势理论、势叠加原理推导了无限大地层水平井多级压裂的产能公式。并且考虑了裂缝导流能力随时间变化对产能的影响。对比了考虑和不考虑裂缝导流能力时变性的产能变化规律。绘制了考虑和不考虑裂缝导流能力时变性的等势线分布图。可看出对多级压裂水平井,裂缝导流能力随时间变化对产能具有很大影响。Potential theory, superposition principle were applied to build horizontal well fracturing productivity equation in infinite reservoirs, and the equation considered changes of fracture conductivity capacity. Contrast re- sults with the non-considering fracture conductivity capacity are shown. The equal-potential line distribution is shown. Results show that conductivity capacity time-varying has great influence on the productivity of multilevel fracturing horizontal wells.
