Product Description 1.Snubbing Workover Rig had 2 kinds, split and whole type.Snubbing Workover Rig split type,which mainly consists of workover rig main body and snubbing unit. The main body adopts normal , upon which add high level braking system, driller's control cabinet and platform ladders connecting with snubbing unit; the snubbing unit is hydraulic control auxiliary snubbing device, which finish work with the help of mast and other downhole tools, such as hydraulic power tong, winch, inner blocking tools and elevator, and the device consists of power system and wellhead part. Power system is skid-mounted structure, that is to install power system, hydraulic power unit and remote console on the skid-mounted base; the wellhead part mainly is consisted of string sealing system, lifting hydraulic cylinder, clamping system, balance discharging Pressure device, working platform, connection panel, driller's console, ladders, escaping slid, pipeline ramp, level just ment and so on; the power system and wellhead part are designed separately for ease of transport or installation. 2.Snubbing Workover Rig Power systemPower system is consisted of diesel engine,clutch transfer case etc,mounted on the power skid.diesel engine, engineering model: C325,with water tank,cooling fan and air pump etc.3.Snubbing Workover Rig Hydraulic systemHydraulic system mainly consist of hydraulic pump, valve group, driller's console, remote console, oil tank, energy accumulator, control pipeline and joint, oil cooling and heating system.The system is equipped with 5 gear pumps, two of which is GPC4-80, flow is 80ml/r, the highest working pressure is 21MPa; the other three of which are designed into treble pump, the model is GPC4-63-63-25, flow is 63ml/r,63ml/r,20ml/r, the highest working pressure is 21 MPa.4.Snubbing Workover Rig BOP String sealing systemString sealing system consist of one set 3FZ18-35 triple ram preventer(special make), two sets FZ18-35 ram preventers, one set FH18-35 annular preventer5.Snubbing Workover Rig Clamping systemClamping system mainly consists of four slips assembly: fixed gravity slip, fixed anti-top slip, traveling gravity slip,traveling anti-top slip.Slip parameter:Loading capacity : 400 kNSlip shell size: 186mmApplicable string scope: 1-3 1/2Control mode: hydraulic control6.Snubbing Workover Rig Lifting cylinderLifting cylinder is mainly used for lifting the stand pipe and overcoming the well-head up force during snubbing operation.Piston diameter: φ140mmCylinder diameter: φ90mm Lifting cylinder stroke: 3.3mMax pressure of lifting cylinder: 21MPaMax lifting load of lifting cylinder: 500kNMax down load of lifting cylinder: 300kN7.Snubbing Workover Rig Connection plateConnection plate is main equipment of snubbing unit, it is used to connect lifting cylinder and traveling slip and transfer and bear fore of lifting cylinder and slip8.Snubbing Workover Rig Balance and pressure relief systemBalanced and pressure relief system consists of two hydraulic plate valve, a double cut wire cross and balanced pipeline and pressure relief line.Second:Snubbing Workover Rig whole typeTechnical parameters of the operating device with pressure(1) Maximum diameter: 186mm(2) Static seal pressure: 35MPa(3) Moving seal pressure: 21MPa(4) Net height of the working state device: 4,800 mm(5) Travel of the lifting cylinder: 2500mm(6) Working pressure of the oil cylinder: 21MPa(7) Fluid control pressure: 8.4-10.5 MPa(8) Upper top force: 600 kN(9) Downward pressure: 400 kN(10) Accumulator volume: 40L 4
