摘要
介绍了压力信号发生器在无线随钻测量系统中的作用,以旋转压力信号发生器的基本工作原理为基础,设计了系统的结构模型,根据系统在工作过程中不同阶段的特点,建立了各个过程中的阀口动态方程;以转速和开度为控制输入,进行了实例仿真。
Firstly the role of the rotary pressure signal generator is introduced in the system of wireless MWD, and based on the principle of the rotary pressure signal generator, a system structure models are designed, according to the different stages of the process, various process valves mouth.dynamic equation is established. Then according to the control signal of rotational speed and the degree, the system is simulate.
