压裂水平井是开发特低渗透油藏的有力工具，但随着开采的深入以及注入水的突进，见水问题已成为困扰其发挥最大效能的重大阻碍。为了研究特低渗透油藏压裂水平井的见水特征，本文在现场找水试验的基础上，分析了压裂水平井见水的原因以及导致含水急剧上升的关键因素，提出了降低含水的具体办法。通过建立数学模型，研究了不同油藏参数、开采参数对生产效果的影响，为特低渗透油藏压裂水平井合理工作制度的确定提供了理论基础。

Fractured horizontal well is a powerful tool in the development of ultra-low permeability reservoir. However, with continuous production and occurrence of injection water fringing, water breakthrough problem has become a significant obstacle to achieving the maximum efficiency of the well. To investigate water breakthrough characteristics of fractured horizontal wells in ultra-low permeability reservoir, based on field experiment of water detection, reasons of water breakthrough and key factors that induces water cut drastic increasing are analyzed, specific methods of reducing water cut are proposed. Through establishing mathematical models, production effects under different reservoir parameters and production parameters are analyzed. And these mathematical models lay a theoretical foundation on how to decide rational working system for fractured horizontal wells in ultra-low permeability reservoir.
