摘要
井眼轨道自动控制技术已成为当今钻井技术研究的热点,其技术关键之一就是地面和井下的信息传输问题。根据井眼轨道自动控制系统的基本构成和实现要求,对信息的传输方式进行了比较和筛选,提出了通过控制钻具旋转速度的方式将地面的指令传送给井下系统的通讯方式。其研究结果将对井眼轨道自动控制系统的设计及实现具有参考价值。
Automatic control technology of well trajectory has become the hot point in the drilling technique, one of the most important technique keys is the information transmission between surface system and downhole system. Based on the basic structure and some realistic requirements of well trajectory automatic control system, through comparing and sieving information transmission methods, a method of downward communication of transmitting surface order to downhole system by controlling the rotation speed of drilling string is presented. The result provides some reference value for the design and realization of well trajectory automatic control system.
