摘要
本文主要介绍了旋转导向钻井系统、遥控变径稳定器、液力加压器等。旋转导向钻井技术是目前世界上最具代表性和先进性的钻井技术,旋转自动导向系统是该技术的核心,并对各系统的导向机构工作原理进行了分析。遥控可变径稳定器是操作者在地面发出控制信号,使其在井下产生相应的径向改变,达到所需的外径尺寸,达到增斜或降斜的目的。液力加压器是一种能量转换装置,利用钻井泵泵压为动力把液体压能转换为钻压的一种新型钻井技术,改变了常规钻井作业时靠下部钻铤重量施加钻压的方式。
This paper describes a rotary steerable drilling system, Remote Controlled Variable - Gauge - Stabilizer, hydraulic pressurized. Rotary steerable drilling technology is the most representative and advanced drilling technology in the world, and the core of the tech- nology is rotary steerable drilling system. This paper analyzes the working principle of each system＇ s steering mechanism. Recreate control signal sent by the variable gauge stabilizer is the operator on the ground, in the downhole produced the corresponding radial change, to a- chieve the required outer diameter size, achieve the goal of increasing oblique or drop. The hydraulic pressurization is an energy conversion device, the use of the drilling pump, the pump pressure as a driving force to the liquid pressure energy is converted to pressure drilling a new type of drilling technology, a conventional drilling operation is changed by a lower drill collar weight is applied WOB.
