Deterioração de poços tubulares: método de videoscopia como ferramenta de análise de poços no RS

Abstract

The wells for groundwater abstraction are a great choice to avoid the crises that periodically affect our country, since the greatest amount of water useful for human consumption is in the form of underground aquifers. Reflecting this growing need in the use of groundwater, there are many wells distributed throughout the national territory which many of those, either for lack of technical and geological knowledge or supervision of responsible parties, don’t have the necessary conditions, constructive and even lithological, to provide water with acceptable quality for human consumptions, although they are still in use. The purpose of this work is to provide information about the correct ways to locate, drill and revitalize a well, and point the problems that arise from the poor elaboration of the same. Considering these assumptions, an analysis through the images acquired from the videoscopy, a tool not so used by all companies but still extremely valuable once that shows clearly the issues that can worsen over time. the problems in the subsurface , and generate important information for more accurate analysis of microstructures , physical parameters such as porosity, ductility / brittleness of the rocks of which these wells are found .
