胜利油田鱼骨状水平分支井钻井技术

Drilling technology of fishbone horizontal multilateral well in Shengli Oilfield

  • 摘要: 为寻求一种更有效、科学和经济的储量动用方式和油藏开发方式,胜利油田开展了鱼骨状水平分支井技术研究与应用。从鱼骨状水平分支井的设计原则着手,对该技术的钻进方式、井身结构、裸眼分支井侧钻技术、钻具组合、地质导向钻井技术、油气层保护技术、完井技术等关键要素进行了研究,同时进行了5口井的现场试验。试验结果表明,试验井产量是普通定向井或直井的3倍多,能极大地提高油藏的动用程度,提高油气藏开发利用率和采收率。鱼骨状水平分支井的成功实施为胜利油田提高油气藏综合开发效益提供了一套全新的技术路线,也为今后该技术的推广应用积累了丰富的经验。

     

    Abstract: In order to seek a more effective,scientific and economic reserves employing mode and reservoir development mode,research and application of fishbone horizontal well technology is carried on in Shengli Oilfield.Some key factors such as drilling in mode,well structure,side tracking technology of open hole branch well,drilling tool assembly,geometry guiding drilling technology,protection technology of oil and gas layer,completion technology,and so on are studied based on design principle of fishbone horizontal multilateral well.Meanwhile,field test of 5 wells is done.It shows that the new technology can improve producing degree of reservoir,utilization ratio of development and recovery of oil and gas reservoir because the yield of testing well is over 3 times than that of ordinary directional well or vertical well.The successful implementation of fishbone horizontal multilateral well provides a new set of technology routes for Shengli Oilfield in improving comprehensive development benefit of oil and gas reservoir and accumulates rich experience for popularization and application of the technology in future.
