Method and device for consolidation of a formation traversed by a deviated well

摘要

the method involves the application of a deviated well (1) of a known process of consolidation by in situ polymerization of a liquid substance (l) is injected into an area (2) to consolidate a injection tube (5) by interaction with a reactive gas g is injected to the result.in order to reduce the area and divided the substance and the gas in this area, are used in combination with a tube wall with openings (11), the terminal (5a), a packer and a containment element (8) for separation of solids (10) moved in the tube in the liquid by the reactive gas.no interaction of it before it reaches the area to consolidate. the injection of the liquid mixture comprises successive stages of movement of the tube (5) and the annulus between it and the shaft (1) and of forcing to do it well into the formation. it is usually preceded by a stage of injection of solvents.;application to the building of horizontal wells producing oil, gas.
