电驱动旋转导向系统新型双台肩导电钻杆研究
发布时间：2023-02-07 19:17
随着石油天然气需求的不断增大,油气资源的勘探开发深度也在不断增加。为了提高单井产量、降低油气开采成本,水平井、丛式井、大位移井等定向井的钻井数量越来越多,对井眼轨迹的控制精度要求越来越高。在此大背景下,各种提高定向井施工精度和施工效率的工具不断出现。其中应用最为广泛的是井底液力马达驱动的旋转导向工具。这种导向工具的地面与井底的通讯方法为泥浆脉冲(MPT)。这种通讯方式或数据传输方式传输速度低、传输数据量小、传输精度易受井底振动的影响。为了提高数据传输速度、克服泥浆脉冲传输(MPT)的缺陷,随后又出现了带缆钻杆(WDP)传输方式。为了确保WDP的传输质量与强度,需在钻柱上安装锂电池电源供电。由于受锂电池耐温能力和供电时间的限制,这种传输方法的适应井深受到限制。为了提高旋转导向工具的数据传输速度与钻井轨迹精度,消除高温高压对现有数据传输方式的影响,开发新一代旋转导向工具迫在眉睫。本研究呈现了双壁通缆钻杆的发展历程,提出了新一代电驱动旋转导向工具的概念和设计。论文从文献调研入手,收集分析了旋转导向工具方面的论文150余篇。分别从电驱动井底工具、泥浆驱动的旋转导向工具、带缆钻杆数据传输方法三方...
