【摘要】 对调制式旋转导向钻井系统稳定平台的控制原理进行了研究,设计了由上、下涡轮发电机、控制轴及电子仓组成的三环控制稳定平台。对稳定平台性能的理论分析和仿真模拟结果表明,国内首创设计的发电机式稳定平台控制系统不但具有良好的稳定性、可控性和可观性,而且当钻井参数在较大范围内发生变化时,系统仍然具有很好的跟踪特性、抑制扰动特性、随动稳定特性及很强的抗干扰能力。更多还原

【Abstract】 The control principle of the servo platform in modulated rotary steerable drilling system was studied. A control system of servo platform composed of upper and lower turbo-dynamotors, platform control axis and electronic storehouse was designed. The theoretical analysis and analogue simulation results show that the platform could keep itself stabilized and has good controllable and visible characteristics. Moreover, the system still has good tracing capacity and anti-jamming capacity when the drilling parameters change in a wide range.更多还原
