摘要
随着定向钻井工艺、工具、测量仪器、钻井装备的不断进步,大位移井钻井技术应运而生并得到快速发展,国內各油田也普遍对该项技术予以重视,并开始着手研究和进行钻井实践。本文在收集国內外部分大位移井钻井资料的基础上,对国内外部分油田大位移井应用现状进行了介绍,并对大位移井钻井中预测和降低扭矩/摩阻技术、钻柱优化设计、井身剖面优化设计、井眼测量及轨迹控制技术、钻井液技术、井眼稳定性、井眼净化评价和改善、固井完井技术、钻井装备等多项关键技术进行了简要讨论。
By the continous advancing of directional drilling process, tools and measuring instruments and drilling equipments, the great displacement dilling technology has come into being and developed quickly, attracted to the interests of domestic oil fields to research and practice it. This paper collects and introdues large sum of informations about the present application situation of it in and out side China and discusses multi key techniques used in the practice such as great displacement drilling prediction, torque/friction reduction, drillstring design optimization, wellbore profile design optimization, well bore measurement and well bore purification evaluatian and modification, cementing and completion and drilling equipments etc. techniques.
