WELL COMPLETION SYSTEM Russian patent published in 2020 - IPC E21B43/08 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: group of inventions relates to oil and gas industry, in particular, to well completion system for connection of multiple mesh filters into well tubular structure, mounted from main pipe sections. System comprises first mesh filter assembly and second mesh filter assembly. Each mesh filter unit comprises the main tubular section mounted as part of the well tubular structure having length in the longitudinal direction. Main pipe section has an outer surface and a tubular element of the mesh filter surrounding the external surface of the main pipe section and connected to it. Tubular element has an outer diameter and a connecting part of the assembly for connection of the end of the first unit of the mesh filter to the end of the second unit of the mesh filter. System further comprises a first tubular member having an inner diameter equal to or greater than the outer diameter of the tubular element of the mesh filter, and located opposite the connecting part of the assembly, so that the fluid flowing through the tubular element of the mesh filter of one of the mesh filter units is allowed to flow outward relative to the connecting part of the assembly.

EFFECT: simplified technology of connection of mesh filters and possibility of their use at blocking of one of filters.
