摘　　要：带压作业是保持井筒内一定压力,不压井、不放井的情况下进行管柱起下的先进井下作业技术,广泛应用于石油钻井中,如油田欠平衡钻井、修完井等工作,应用堵塞器等工具将管柱内部封堵,利用带压作业机的动密封型防喷器控制环空压力,通过举升系统和旋转系统上举、下压和旋转管柱,以实现带压作业。因此,本文主要进行带压作业技术概述,探究石油钻井带压作业技术工艺的应用。With pressure operation is to keep the pressure in the shaft,without the well,well under the advanced downhole operation technology,widely used in oil drilling,such as oil f ield under balance drilling,repair and other work,the application of plugging tools to control the annular pressure,through the lifting system and rotating system lifting,down and rotating string,to realize the pressure operation.Therefore,this paper mainly discusses the overview of belt pressure technology and explores the application of petroleum drilling belt pressure technology.
