Badania zużycia korozyjnego rur wydobywczych stosowanych w odwiercie podziemnego magazynu gazu Swarzów 22
(2007) Artymiuk, Jan; Bednarz, Stanisław
The presence of hydrogen sulfide in the natural gas exploited from the underground gas storage Swarzów is a serious problem. Hydrogen sulfide causes corrosion of the production pipes and the surface manifold, which affects the exploitation parameters of the USG and its technical condition. The destructive activity of hydrogen sulfide causes that the well loses its exploitation parameters, is much faster contaminated with the corrosion products, requires cleaning and washing with special agents. This effect is especially well visible in the well Swarzów 22. The well was worked over: the production pipes were tripped out and subjected to strength-structural analyses to confirm the degree of damaging with corrosion and the acid environment.

Porównanie aluminiowych rur płuczkowych ze stalowymi
(2007) Artymiuk, Jan
Drill string is a long cylinder with a longitudinal opening inside, consisting of sections (drilling pipes and collars) from 8.5 m to 9.5 m long and from 3 1/2'' to 6 5/8'' in diameter, fastened by threaded connections. The most frequently applied material is steel of various strength parameters, of considerable weight as compared to the strength parameters. Analyses were made to find components which could substitute the traditional steel material with another one, equally strong but lighter. Every kilogram on hook means bigger energy consumption of the rig and bigger (and so heavier) elements in the drawing system. Attempts were made to compare mud pipes made of steel and aluminum alloys. It was indicated that further research and construction works on aluminum drilling pipes should be continued.
