摘要: A method for cleaning a plugged gravel pack in a subterranean wellbore is provided. The method comprises the steps of using a pressure pulsating jet and a tangential vortex to deliver a pressure pulsating treatment fluid into the gravel pack wherein soluble plugging materials in the gravel pack are dissolved by the treatment fluid and insoluble plugging materials are moved through the gravel pack and circulated out of the wellbore. The treatment fluid is driven into the gravel pack to dissolve soluble fines and displace insoluble fines from the interstitial pore spaces of the gravel pack.

摘要: In some embodiments, apparatus useful for providing tubing into an underwater well includes at least one surface injector and at least one underwater injector. The surface injector is adapted and arranged to control the movement of the tubing into and out of the underground well below the sea floor during normal operations. At least one surface injector and/or underwater injector is arranged and adapted to maintain the tubing in substantial tension between the surface and underwater injectors.
