| 摘要 |
This invention relates to equipment and a subsea pumping system using a subsea module installed on the sea bed, preferably away from a production well and intended to pump hydrocarbons having a high associated gas fraction produced by one or more subsea production wells to the surface. One object of this invention is achieved by means of the design of a pumping module (PM) which is linked to pumping equipment already present in a production well and which basically comprises: an inlet pipe (2), separator equipment (3), a first pump (4) and a second pump (8). In the subsea pumping system for the production of hydrocarbons with a high gas fraction, the other object of this invention, when oil is pumped from the production well (P) the well pump (13) increases the energy of the fluid in the form of pressure and transmits this increase in energy in the form of an increase in suction pressure in the second pump (8) of the subsea module (PM). |
