FIELD: well drilling and completion.
SUBSTANCE: device has expansible tube having wall with a number of through cuts. Some cuts are formed of bent compressed members and may expand in radial direction. Expansible means has bistable cells creating tubular structure. Each expansible cell has thick compressed member and bent pliable link, which may be converted into expanded state. Axial tube length is constant during tube expansion. Expansible system comprises means connected to communication line for information receiving.
EFFECT: reduced force for tube expansion from radially compressed state.
