摘　　要：精细控制压力钻井技术是针对狭窄压力窗口而发展起来的,节流压力控制系统是其关键技术之一。现有的节流压力控制系统大多采用液动控制方式,存在3方面不足。提出了电动节流压力控制系统设计方案,并对各功能模块进行了详细设计。通过对电动执行器与节流阀的力学分析,证明方案可行,并对电动执行器进行了优选和合理性验证。该系统克服了传统液压控制的不足,可以用于精细控压钻井作业的节流压力控制。Preciese managed pressure drilling technology is developed by narrow window pressure. Throttle pressure control system is one of the key technolo ing. The existing throttling control system mostly used is gles hyd of preciese managed pressure drill raulic control method, and shortage exists in three aspects. The electric throttle pressure drilling control system is proposed for the precise managed pressure drilling and the functional modules of the detailed design are proposed as Nell. Through the analysis of electric actuators wad the mechanics of the throttle, the feasibility of the solutions is verified. The electric actuator optimization and rationality is verified. This sys- tem overcomes the drawback of the existing hydraulic control system and can be used for fine con- trol pressure drilling the well back-pressure accurate control.
