                       旋转←导向钻井系统是当今石油钻井工程领域最重要的前沿装备之一,集机、电、液、信息和控☆制技术于一体,在近钻头端与MWD或LWD配合完成虫神都无可奈何导向钻井⌒。是实现石油钻井向数字化、信息化、自动化方向发展的核心技术和重大装备,可广泛应用于陆地和海洋环境下的超深井、水平井、大位移井、分支井等特殊你又何必抓住此事不放呢钻井工艺的导向作业。
                       旋转不知道他原本就是这副眼神导向钻井系统由发电系统、电力传输系统、机械系统、电动机、液压系统、定位总成、测量系统懵了等构成。在钻井过程中,泥浆提供动力,带动发电机发电,供给整个导向系白炽灯统,主控板々采集压力、位移及地面上■位机的信号进行数据分析处理,并向执行机构发看起来很朴实送指令,电机泵液压系统接受到指令后控制翼肋伸出或收回,分别在不同方向上对井壁施加作用力,通过三个支撑翼肋的控◥制,实现导向∮钻进。

                 

                Rotary steerable drilling system 

                Rotary steerable drilling system is one of the most important equipment in oil drilling field now, and it is a combination of mechanical, electrical, hydraulic, information and control technologies. It can execute steerable drilling with the help of MWD or LWD at the near-bit end. This equipment is the core technique and crucial to realize the digitization, informatization, automation of the oil drilling, and it is widely used for the steerable drilling of ground and offshore wells such as ultra-deep wells, horizontal wells, extended reach wells, and branch wells, etc.
                Rotary steerable drilling system consists of various subsystems including power generation, power transmission, mechanical, motor, hydraulic, positioning and measurement. During drilling, the drilling mud well supply the generator the power for generating electricity to the whole steerable drilling system. The control pad collects pressure, deviation and signals from the ground for data analysis, and sends instructions to the actuator. After receiving the instructions, the hydraulic system of the motor pump will control the extension and drawback movement of the steerable ribs, then the well wall is forced from different directions, and the steerable drilling is realized via the control of the three steerable ribs.
