分支井技术是适应当前油田发展需要的一项重要技术。分支井改善了泄油条件、为提高产量和采收率提供巨大的潜力。文章对分支井的井眼轨道设计、钻井液设计、侧钻方式进行了介绍。由于完井技术在设计过程中占有重要的地位,所以从完井方式和主、支井眼密封及连通对其进行阐述。

Multilateral well is an important technique that suit to the developmental need of oil fields. The multiblateral well offers large potential to improve drainage area, increases production and enhances the oil recovery. This paper introduces the wellpath design, drillstring design, drilling fluid, and sidetracking. Well completion is emphasized in this paper because it is important during the engineering design of multilateral well.
