摘要
井眼轨道自动控制技术是当今世界钻井技术的最新领域,是一项跨世纪的高新技术。文中对井眼轨道自动控制系统设计的有关基本问题进行了初步的分析。给出了井眼轨道自动控制的目标及其数学描述,并根据系统的功能分配,提出了井眼轨道自动控制系统的基本结构即由两个分系统构成的监督控制结构;然后分别对这两个分系统的结构特点以及控制方法进行了分析;阐明了井眼轨道自动控制系统的基本设计原则。
Automatic control technology of bit trajectory is up to date field of drilling engineering in the world.Basic problems on design of automatic control system of bit trajectory are analyzed in this paper.At first,the objective of automatic control of bit trajectory is established and expressed in mathematics;according to the arrangement of system function,the basic structure of automatic control system of bit trajectory should be the supervising control structure,which consists of two branch systems.The structural features and control methods of these branch systems are discussed.Finally,the basic principles are clarified for the design of automatic control system of bit trajectory,which has important guiding sence.
