Wiertnicze wyroby rurowe ze stopów aluminium
(2007) Artymiuk, Jan
Pipe products and their connections constitute the most significant group of products oil industry, as the success and safety of exploration and exploitation depends on them. The transport of hydrocarbons greatly depends on these products. Pipes and connections have a variety of shapes and design. This especially applies to the connections and subs. In a majority of cases this is steel of various strength and chemical properties. The low resistivity to corrosion and considerable weight are the main disadvantages of steel products. Researches are made on finding new materials which would substitute the traditional steel pipe products. Pipes made of aluminum alloys reveal good results. The pipe products made of aluminum alloys and their applicability for exploration and exploitation works are discussed in the paper.
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.
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.
Metody perforacji kumulacyjnej w udostępnianiu złóż węglowodorów
(2007) Frodyma, Antoni; Wilk, Zenon
Perforation using shaped charges, as a method of deposit development in oil and gas mining is, in practice, the only commonly used method of obtaining hydraulic interconnection of cased borehole and productive reservoir layer. The study presents historical outline of cumulative perforation and development of basic techniques in this domain. It discusses various conveyance methods - wireline, production tubing (TCP) and coiled tubing (CT), through tubing perforation (TTP), as well as methods of ignition depending on job technology used. Two basic carrier concepts - hollow carrier (closed type) and bar carrier (open type) are characterised, as well as sets of shooting means (detonating cords, shaped charges, detonation initiators) that can be purposefully used with them. The basic requirements, that should be fulfilled by shaped charges depending on main task of perforation (horizon opening, preparation for intensification job - fracturing, for example, as well as special jobs - i.e. restoring of lost circulation with perforator - puncher) has also been presented. In context of this review, currently used and approved sets of shooting equipment and means for cumulative perforation are presented, including some new approaches, such as technology of reactive liners and perfo-generators.
Ochrona złóż ropy naftowej i gazu ziemnego podczas udostępniania i prac rekonstrukcyjnych poprzez użycie cieczy wiertniczych zawierających niskotoksyczne sole mrówczanowe
(2007) Herman, Zdzisław; Uliasz, Małgorzata
This paper presents laboratory test of dribling fluids based on potassium and cesium formats. Possibilities of field applications of above fluids are discussed for completions and workower operations.
