FIELD: transportation.
SUBSTANCE: invention relates to linear structures of underground pipelines, namely, to methods of producing watertight isolation of inspection process wells. Proposed method comprises the following steps: production of sealed shell from polymer membrane in production conditions; stage of preparatory works at the platform near the process well on the linear part of the main oil pipeline; stage of tight shell installation on process well; stage of final works.
EFFECT: improving operational reliability of waterproofing restoration and increasing durability of waterproofing due to application of shell from polymer membrane.
