摘要
大位移井能够达到钻遇多套砂体的目的,增大井筒与储层接触面积,在油气田钻井中取得了显著的应用效果。水力振荡器和旋转导向系统单独应用于大位移井,能够提升钻井时效和定向控制能力,但两种工具同时使用的兼容性尚未得到分析和验证。本文基于水力振荡器和旋转导向系统的原理特点、结构类型及应用情况,分析了使用水力振荡器配合旋转导向系统使用时的兼容性优势并给出了现场应用案例证明。研究结果表明:两种工具配合使用可以将优势相结合,消除单独使用的问题,以更加稳定的低水平钻井参数获得更高的钻井效率。本文研究结果为现场水力振荡器配合旋转导向系统的使用提供了可参考依据,为大位移井钻井的提速提效技术提供了支撑。
Extended reach wells can achieve the goal of encountering multiple sets of sand bodies,increasing the contact area between the wellbore and the reservoir,and have achieved significant application effects in oil and gasfield drilling.The separate application of hydraulic oscillators and rotary steerable systems in large displacement wells can improve drilling efficiency and directional control capabilities,but the compatibility of using both tools simultaneously has not been analyzed and verified.This article analyzes the compatibility advantages of using a hydraulic oscillator in conjunction with a rotary steerable system based on the principle characteristics,structural types,and application situations of hydraulic oscillators and rotary steerable systems,and provides on-site application cases to prove their effectiveness.The research results indicate that the combination of the two tools can combine their advantages,eliminate the problem of using them alone,and achieve higher drilling efficiency with more stable low-level drilling parameters.The research results of this article provide a reference basis for the use of on-site hydraulic oscillators in conjunction with rotary steerable systems,and support the speed and efficiency improvement technology for drilling large displacement wells.
