摘要
以水平井为基本特征的复杂结构井是低渗透、非常规、海洋及深层等复杂油气田高效开发的先进井型技术,在国内外备受关注。文章介绍了复杂结构井的基本概念及应用场景,梳理了复杂结构井定向钻井理论与技术的若干重要进展,主要包括旋转导向钻井、磁导向钻井及大位移钻井等定向钻井技术,分析了复杂结构井定向钻井面临的技术挑战,提出了相应的对策与建议,以期为中国复杂结构井定向钻井理论与技术创新发展提供参考。
Complex wells,with horizontal wells as the basic features,serve as advanced well-type technologies for the efficient development of complicated oil&gas fields with low-permeability,unconventional,marine,and deep features,and they have attracted a lot of attention in China and abroad.This article first introduces the concept of complex wells and their application scenarios.Next,some important developments in directional drilling theories and technologies for complex wells are sorted out,including rotary steerable drilling technology,magnetic steering drilling technology,and extended-reach drilling technology.At last,the challenges in directional drilling of complex wells are analyzed,and the corresponding suggestions are put forward,so as to provide support for directional drilling of complex wells in terms of theoretical and technical innovations.
