DESIGN AND APPLICATION OF BUTTRESS THREAD BUCKLE RISER

摘要：

At present, offshore drilling operations often use buttress thread casing as surface casing. The design conception of buttress thread casing is conies from the offshore drillings demands and this kind of casing is mainly used as surface casing. This paper has taken strength experiment, numerical simulation analysis and field test, the research results show that the various parameters of buttress thread casing fully complies with the drilling design requirements and the offshore oilfield production demands. This product can reduce drilling cost effectively, improve working efficiency and safety, and realize manufacture domestically. M eanwhile, the development of this project will fill the blank of the ERW (Electrical Resistance Weld) casing in CNOOC (China National Offshore Oil Corporation), and have a broad prospect of application.
