| 发明名称 | Blockage removal apparatus and method | ||
| 摘要 | The invention provides a method and apparatus for removing a blockage from a fluid conduit. An apparatus comprises a first portion containing a fluid volume separated from the fluid conduit via a controllable valve. The valve is cyclically opened and closed such that a pressure differential between the first portion and the fluid conduit causes a series of pressure pulses in the fluid conduit. The pressure differential is regulated to control the amplitude of the pressure pulses of the series. | ||

| 主权项 | 1. A method of removing a blockage from a fluid conduit in a hydrocarbon production or transportation system, the method comprising: providing an apparatus comprising a first portion containing a fluid volume separated from the fluid conduit via a controllable valve; pressurizing the first portion of the apparatus to a first fluid pressure; cyclically opening and closing the controllable valve such that a pressure differential between the first portion and the fluid conduit causes a series of pressure pulses in the fluid conduit; monitoring a change in pressure conditions in the fluid conduit; compensating for a measured change in pressure conditions in the fluid conduit by adjusting a fluid pressure in the first portion, to thereby regulate the pressure differential and control the amplitude of the pressure pulses of the series. | ||
