摘　　要：智能分层注水井井下测试数据需要无线向上传输,根据注入水流动特性和发生脉冲的基本原理,设计发生脉冲信号的转阀基本结构和形状。利用优化设计软件对其阀口机械结构、性能参数进行优化,对不同工况下的旋转扭矩和脉冲振幅进行了模拟。优化后的转阀阀口型线为扇形、阀口数量为4个,产生的压力脉冲幅值达到了0.8 MPa以上,能够在注水量只有50 m^(3)/d的情况下实现井下测试数据的精确上传,为智能注水井实现无线传输提供了技术支撑。根据以上优化结果设计了一种能够把注入水作为动力传输介质的可以产生连续脉冲的注水井转阀式脉冲信号发生器,其传输方式为采用正脉冲向上传输。下一步将进行脉冲器的试制与室内试验,进一步优化其结构,达到现场应用需求。The downhole test data of intelligent stratified water injection wells needs to be transmitted upwards wirelessly.According to the basic principles of injected water flow characteristics and pulse generation,the basic structure and shape of the rotary valve that generated the pulse signal was designed.The mechanical structure and performance parameters of the valve port were optimized by the optimization design software,and the rotation torque and pulse pressure amplitude under different working conditions were simulated.The optimized design of the rotary valve port type line is a fan shape and the number of valve ports is four.The generated pressure pulse amplitude reaches more than 0.8 MPa,which can successfully realize the accurate upload of downhole test data when the water injection volume is only 50 m^(3)/d,which provides technical support for the realization of wireless transmission of intelligent water injection wells.Based on the above optimized results,a water injection well rotary valve pulse signal generator that could generate continuous pulses with injected water as the power transmission medium was designed.Its transmission mode adopts positive pulse upward transmission.The next step will be the trial production and testing of the pulser.The indoor test further optimizes its structure to meet the requirements of field application.
