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 field 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.
