System Design Of Hydraulic For Jet Pump Rank Sand

In the process of oil exploitation, wear away gravely since the oil layer produces a grit bringing about a component gravely,various machinery oil extraction equipment life time has shortened greatly, has increased oil extraction cost, has improved the stable high yield having managed an intensity , having affected crude oil's grave. For this purpose, prevent sands , clear various grit method has got exploitation and has applied. For this purpose, prevent sands , clear various grit method has got exploitation and has applied. In common use be that the oil field purifies water circulation sand cut law, but, hide a depth to the oil layer coming to say big, out the stable oil well of grit this routine clear grit method is difficult to fit in with. For this purpose, have suggested that the oil well making use of an injection pump to be in progress cleans up the grit method at the shaft bottom.The basis in the data surveying large amount of document has been listed in the main body of a book, has built systematic injection pump row grit calculation model , has ascertained the sensibility having rubbed a loss coefficient, and then having built injection pump performance data equation , gas falling in row grit condition losing characteristic property equation , the pump outlet returning pressure falling in row grit condition equation and by the fact that the interior experiment has studied the law rubbing the loss coefficient change. Result liquid strengthens the two-phase perpendicularity being in charge of stream calculation model finding the solution , system looks on injection pump row grit as a entire system from oil layer to the floor having carried out the application software having designed, and developing a scene.
