摘　　要：为了防止水平井的底水锥进,设计了通道-喷嘴式流入控制器,由带流槽的隔板和螺旋通道组成,隔板中可根据实际需要插入不同尺寸的流槽。通过延长井液流入高峰期,达到延长气井生产寿命、减少水锥量、提高采收率的目的。CFD分析结果表明:该工具对流体的黏度敏感性低,具有低冲蚀、高抗堵塞的特点,性能优于同类产品。In order to prevent the bottom water of the horiozntal coning feeding toward the heel of the well, and a new Inflow Control Devices（ICD）, channel nozzle ICD, was designed, which fea- tures a series of helical passages and bulkhead which can be thrusted different slots in a maze con- figuration. ICD can extend the well life by extending the plateau period,minimize water and gas coning,minimize annular flow and increase recovery. CFD modeling and analysis of the channel nozzle ICD shows Channel-nozzle ICD is fluid viscosity insensitive, also maintaining low erosion potential （lower flow velocities） and high plugging resistance （large flow area）. The performance of channel-nozzle ICD is better than similar products.
