【摘要】 剪切闸板是闸板防喷器的核心部件之一,其技术性能直接关系到整个井控系统工作的可靠性。剪切闸板一旦失效,将可能发生井喷、井涌等严重事故,危及地面人员及装备的安全,增加钻井、完井过程中的作业风险。分析了剪切闸板量化评价方法的意义以及目前剪切闸板评价存在的问题,结合现场应用条件,基于机器视觉技术和图像处理技术建立了一套科学、快速、高精度的剪切闸板量化评价方法,为钻井完井的安全作业提供保障,对完善剪切闸板量化检测技术具有一定的指导作用。更多还原

【Abstract】 Shear ram is one of the core components of the blowout preventer,and its technical performance is directly related to the success or failure of the whole well control system.Once the shear rams fail,it will be possible to have a serious accident,such as blowout well,endangering the safety of ground personnel and equipment,and increase the operational risk in the process of drilling and completion.The significance of the quantitative evaluation method of shear rams and the problems existing in the present evaluation method were analyzed in this paper to establish a set of scientific,fast and accurate method for the quantitative evaluation of shear rams,which is based on machine vision technology and image processing technology.更多还原
