METHOD OF KILLING OF DEEP AND ULTRADEEP WELLS AND PIPELINES Russian patent published in 1997 - IPC

FIELD: oil and gas production, in particular, killing of emergency wells and pipelines with oil, gas, water to eliminate accidents and oil spills, and spills of formation waters on terrain and open water reservoirs, and prevention of gas blowouts to atmosphere. SUBSTANCE: freezing of emergency flow of well products and pipeline products is carried out by injection into them of magnetic or electrically active particles with application of external electromagnetic field, magnetic or electric field, including injection of magnetic and electrically active particles together with oil, water, gas or thermosetting resin or coolant with solidification of preset composition under the effect of temperature of deepest flow, and, if required, also with application of external heating. Method makes it possible to quickly brake the emergency flow with electromagnetic particles in zone of action of magnetic or electric (electromagnetic) field, or freezing, or solidification of colloid-dispersed fluid or gas suspension with magnetic particles in preset point before the break point or with formation of salamander inside well or pipeline in form of cutoff plug or solidified inclusions in zone of elevated temperatures in wellbore in injection of epoxy-diane resin or monomer with magnetic or electrically active particles in form of powder or colloid-dispersed suspension or with additives of hardener catalyst to monomex FAM of benzene sulfonic acid, or paratoluene sulfonic acid. EFFECT: higher efficiency. 14 cl, 1 tbl
