       扭转导向钻井体系是现今石油钻井工程范畴最重要的前沿配备之一,集机、电、液、信息和掌握手艺于一体,在近钻头端与MWD或LWD共同完成导向钻井。是实现石油钻井向数字化、信息化、自动化标的目的开展的核心技术和严重配备,可普遍应用于陆地和海洋环境下的超深井、程度井、大位移井、分支井等特别钻井工艺的导向功课。
       扭转导向钻井体系由发电体系、电力传输体系、机器体系、电动机、液压体系、定位总成、丈量体系等组成。在钻井历程中,泥浆供给动力,动员发电机发电,供应全部导向体系,主控板收罗压力、位移及空中上位机的旌旗灯号停止数据阐发处置,并向执行机构发送指令,机电泵液压体系承受到指令后掌握翼肋伸出或发出,别离在不同方向上对井壁施加作用力,经由过程三个支持翼肋的掌握,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.
