摘要
井眼轨道控制理论和技术是石油钻井工程的基础和关键。随着定向井、丛式井和水平井的发展,井眼轨道控制难度不断增加。当前面临的一个重要问题是如何开展进一步的理论研究,如何把现有的理论成果转化为实际控制手段,以提高控制精度和降低钻井成本。本文简单回顾了井眼轨道控制理沦和技术的发展过程;综述了当前的技术现状和需要解决的问题;在此基础上,用控制理论观点对井眼轨道控制研究进行分析和思考,并对今后的研究方向作了展望。
The theory and technology of wellbore trajectory control is the key and fundamental is- sue in petroleum drilling engineering. With the development of directional, cluster and hori- zontal wells, the degree of difficulty about wellbore trajectory control increases gradually. One important problem is how to undertake a further theoretical research and how to trans- fer the existing theoretical achievements to practical means of control in order to increase control accuracy and save drilling cost. This paper reviews the development of trajectory control theory and summarizes state-of-art of technology and existing problems. A new idea and conception about development on this topic are presented.
