FIELD: oil and gas industry, particularly construction of wells with horizontal and inclined bores having complicated configurations.
SUBSTANCE: method involves penetrating productive reservoir and installing casing pipe extending up to productive reservoir roof; delivering gravel composition to horizontal well bore by means of flow string; circulating liquid to wash-out gravel composition from flow string into horizontal well bore along with simultaneous flow string lifting; compacting gravel composition by periodic flow string lifting stopping along with gravel composition washing-out and flow string lifting so that flow string rests upon developed gravel filter.
EFFECT: possibility to create gravel filter during construction of well having inclined and horizontal bores having complicated configurations.
