The rebound of settlement can be extended remotamenta

摘要

Invention patent: b "rebound of settlement can be extended to remotely" d . A rebound of settlement is filled in a series of necklaces that extend from a ring frangu00edvel.The collars are guided to a cavity which itself is in a recess in the housing of the well head.The extension of the rebound of the settlement in its retracted position allows a drill column additional coating is passed.Which is nominally next the diameter inerno hole seal of the housing of the well head.The ability to add a column casing drilling additional accommodation of the well head of a particular size allows the isolation of production areas of water near theThe surface of an effective way in terms of cost, where the mud used to control the production of water is recovered.In a course subsequ00b3ente after the coating more be hung below the body, a tool fixture fits in the rings which support the necklaces that define the rebound of the settlement.The hydraulic pressure created in the tool fixture operates a piston to break a portion of the ring that supports the necklaces.So that they are directed and restrained in a fixed position where they define a cam hole for laying in a service subsequ00b3ente coating action is made in order to giveThe staff of the surface as a sign that the beads were atuados to position for acetarem next drill column of revetimentos.
