摘要
为提高油田的生产效率,满足油田分层注水智能化需求,文中设计一种油田智能分层注水井下控制系统。该系统主要由井下注水板、井下压力传感器和直流电机等部分组成。井下注水板的主要功能是处理井下压力传感器数据,接收井上人员发送的控制指令,以及通过控制直流电机转动调节井下注水阀门的开度大小。为提高系统抗电机等噪声的能力,创新性地设计一种抗噪电阻编码器模块,用于代替霍尔编码器测量电机的旋转角度。在井口端设备与井下注水设备之间通信时,系统通过设定压力波通信协议减少打压设备的开关次数,在稳定传输数据的前提下降低系统功耗。实际测试结果表明,所设计的井下注水板在模拟的井下高温环境中能稳定工作,可为油田智能化注水生产提供一种有效的解决方案。
In order to improve the production efficiency of oil field and meet the intelligent demand of layered water injection in oil field,a downhole control system for intelligent layered water injection in oil field is designed.The system is mainly composed of downhole water injection board,downhole pressure sensor and DC motor.The main functions of the downhole water injection board are to process the data of the downhole pressure sensor,receive the control instructions sent by the personnel on the ground,and adjust the opening degree of the downhole water injection valve by controlling the rotation of the DC motor.In order to improve the anti noise ability of the system,the anti noise resistance encoder module is innovatively designed to replace the Hall encoder to measure the rotation angle of the motor.When communicating between wellhead end equipment and downhole water injection equipment,the system can reduce the switching times of pressure equipment by setting a pressure wave communication protocol,and reduce the system power consumption on the premise of stable data transmission.The actual testing results show that the designed downhole water injection board can work stably in the simulated downhole high temperature environment,which can provide an effective solution for the intelligent water injection of the oilfield.
