FIELD: drilling of soil or rock.
SUBSTANCE: invention relates to plugs for drilling well. Plug for drilled well with walls comprises, at least one capsule of fluid-impermeable material, wherein capsule is made so that there is gap between capsule and walls, when capsule is inserted into the well; at least one charge; wherein activating of said at least one of ignitor capsule can expand; coupling for connection of pipeline with capsule; through hole passes through capsule, so that fluid can flow through capsule and be discharged through pipeline and valve to open and close feedthrough hole.
EFFECT: technical result consists in isolation of drill hole.
