摘　　要：根据压裂缝井试井理论,采用试井分析方法对庄5井压前压后试井资料进行了对比分析。结合压裂施工工艺及压后压降曲线分析,评价了庄5井压裂层段的压裂效果,得到了造成该井压裂效果不佳的原因主要有:压裂液对地层造成了一定伤害;压后裂缝半长短,说明地层没有完全压开;地层物性变差;地层存在出水现象等,为该井的合理开发和制定下步增产措施方案提供了参考依据。According to the well testing theory of fractured well and using well testing analysis method, some comparison and analysis of pre-fracture and post fracture testing data of Zhuang5 well has been done. By analyzing the pre-fracture and post fracture build-up plot, the fracture effect is evaluated and the main reasons causing the failure of the fracturing are that of damage to the reservoir of fracturing fluid, being too short of the fracture half-length which shows the phenomena of reservoir not being opened completely, getting worse of the property and yielding water that provides a scientific basis for the next step of exploration and development plan.
