在油气井钻进作业过程中,钻柱长期工作在充满钻井液的狭长井筒里,其受到井底压力、摩擦、岩石硬度变化的影响,受力情况非常复杂,会产生多种形式的振动,这些是影响钻具寿命和钻进效率的最主要因素.为系统分析工程界和学术界长期以来普遍关注的钻柱系统振动的有效控制问题,对近几十年来国内外在钻杆振动控制上使用的各种方法进行了分类和归纳,总结了各种方法的特点、应用场景以及不足之处,并对钻柱系统振动控制技术的发展趋势进行了展望.研究结果表明:①现有的钻柱振动主动控制主要集中于单一方向(扭转振动)和 2 个方向的耦联振动(纵扭耦联振动),且控制参数主要集中于钻压和扭矩,仅控制单方向的振动和单参数的调节,效果将很难保证;②被动控制是通过改变钻柱系统自身的结构或设计参数来抑制其振动,控制过程不受结构响应和外部干扰的影响,虽然效果有较大的局限性,但仍应在设计阶段给与足够的重视;③今后钻柱振动控制将朝着同时基于地面和井下测量数据,纵、横、扭 3 个方向联合控制的方向发展.结论认为,钻杆振动往往是几种基本振动形式的耦联,并具有明显的非线性特征,基于数据驱动的钻进系统动力学建模、考虑模型不确定性的现代鲁棒自适应控制技术以及新兴的人工智能技术将会成为未来钻柱振动研究和发展的主流趋势.
Research progress and prospect in active and passive control of drill string vibration
In the drilling process of oil and gas wells,drill string operates in a narrow wellbore filled with drilling fluid for a long time.Under the influence of bottom-hole pressure,friction and rock hardness change,it undergoes complex stress and generates different forms of vibration.These are the main factors influencing the service life and drilling efficiency of the drilling tool.The effective control of drill string system vibration has long been a common concern in the engineering and academic fields.In order to systematically analyze this problem,this paper categorizes and summarizes various methods used for drill string vibration control over the past few decades.Based on this,the characteristics,application scenarios and deficiencies of these methods are summarized.In addition,the development trends of the drill string system vibration control technologies are predicted.And the following research results are obtained.First,the existing active control of drill string vibration mainly focuses on single-direction vibration(torsional vibration)and two-direction coupled vibration(longitudinal-torsional coupled vibration),and the control parameters mainly focus on weight on bit(WOB)and torque.It only controls the single-direction vibration and the single-parameter regulation,so the effect is hardly satisfactory.Second,the passive control is to suppress the vibration of drill string system by changing its structure or design parameters,and its control process is not influenced by structural response and external interference.The control effect has greater limitation,but it still deserves enough attention in the design stage.Third,the drill string vibration control will develop to the coupled vibration control in longitudinal,transverse and torsional directions based on both surface and downhole measurement data.In conclusion,drill string vibration is often the coupling of several basic vibrations,and has obvious nonlinear characteristics,so data-driven drilling system dynamics modeling,modern robust adaptive control technology considering model uncertainty,and emerging artificial intelligence technology may become the mainstream trend of drill string vibration research in the future.
