We use annuluar blowout preventer and ram blowout preventer to control annuluar pressure btween production tubing and casing. Ⅰ Application and solution Ⅰ Application and solution Annular BOP Ram BOP B. We have designed special and dedicated downhole plug and external plug to solve seal problem.Picture showed blow are plugs we have designed for control downhole pressure. Ⅰ Application and solution Ⅰ Application and solution A. For better pressure control performance,we have applied every advanced technology.Up to now, we have designed snubbing unit and downholes with intellectual property.We are professional to control well under 70MPa. external plug Workover mode Independent mode Snubbing unit for E-line type well Snubbing unit for pump type wells Snubbing unit for workover Ⅱ Specification and superiority Ⅱ Specification and superiority B. For years study and research, we designed series downhole tools to control downhole tubing pressure with intellectual property that can solve most well condition. Such as: Slipper plug for oil/injection wells. It runs down and plug well in by self-weight. Well of 2 3/8〞、2 7/8〞、3 1/2〞tubing under 21MPa is applicated。 Completion tubing plug for beam pump type well. Its usally Initialized at the end of tubing for oil well under 35MPa. Ⅱ Specification and superiority Ⅱ Specification and superiority Machanical reusable plug. Its usally set down by slick line and settled by repeating pulling up and running down. Its designed for well with 2 3/8〞,2 7/8〞,3 1/2〞tubing under 35MPa. Hydraulic reusable plug. Its usally set down by coil tubing at appreciated depth。Its settle by pump
