Contemporary technological fluids for well completion and work-over. Part 1
The article considers contemporary technological liquids used for qualitative opening of productive layers and wells work-over. Some examples of using contemporary compositions (liquids on hydrocarbon basis, aphrons technology, bio-polymer compositions, liquids, forming oleophilic filtration cake) at the fields of Russia in various geological-technical conditions are presented. Solid phase effect, including drilling slurry, on technological liquids properties as well as on quality of productive layers opening is discussed.
