FIELD: oil-and-gas production.
SUBSTANCE: bed treatment fluid thickened by viscosity increased agent (VIA) contains: water, VIA in amount sufficient for water viscosity increase, at least one internal destructing agent, at least one fluid loss adjusting agent, and at least one viscosity booster selected from the group consisting of pyroelectric particles, piezoelectric particles and mix thereof. Proposed method comprises making composition of aforesaid fluid, injecting it into bed and reducing viscosity of said fluid. Invention is developed in dependent clauses.
EFFECT: fast and complete fluid and pseudo filtration sediment removal, improved productivity of oil reservoir.
