| titleOfInvention | Method for improvement of fibre plugging |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: invention is referred to method for improvement of fibre plugging and in this way to controlled absorption of drilling mud during well drilling. Method for plugging geologic formation includes introduction to the well of compound consisting of fluid with initial viscosity of at least 100 cP; and fibre. At that fibre is selected from fibre based on hydroxy propionic acid polymer, basalt fibre, soya beans fibre, fibre based on glycolic acid polymer, fibre based on polyethylene terephthalate, fibre based on polyvinyl alcohol, fibreglass, polyether fibre and combination of the above fibre having diameter from 1mcm up to 1000 mcm and length from 2 mm and 2.5 mm. Viscosity reducing agent is injected to the well with the above compound or separately. At that fibre flocculates at reduced viscosity of the medium. n EFFECT: technical output is the increased efficiency of plugging. n 9 cl, 7 dwg, 2 tbl, 7 ex |
