METHOD AND DEVICE FOR STRENGHTENING A FORMATION DRILLED THROUGH BY A DEVIATED WELL

摘要

the method involves the application of a deviated well amade by in situ polymerization of a buildingliquid is injected into an area to build athe injection tube by interaction with a reactive gas g is injectedits result. in order to limit the area of intervention and of allocatingsubstance and the gas in this area are used in combination with athe tube wall with openings over its entire partsenior year, a packer containment and an element of separation of solidsmoved in the tube in the liquid, gasin response, which prevents interaction of it before itis the area to consolidate. the injection of the liquid mixtureconsists of successive phases of movement between the inside of thethe tube and the annulus between it and the shaft and forced to dowell into the formation. it is usually preceded by ainjection phase solvents.application to the building of horizontal wellsproduction of petroleum effluents.
