The Successful Application of Shelf Rotating Liner Cementing Technology in Chengbei Oil Field

摘要

Rotating liner cementing technology can significantly improve the cementing quality, which has gained more and more attention from domestic cementing industry. Through sufficient ground tests and underground simulation tests, it has been proved that all technical parameters of the rotating liner cementing tool developed by SINOPEC Shelfoil Petroleum Equipment & Services Co., Ltd were consistent with the design and that the tool could be put into industrial application. Taking 11NC-1 well in Shengli Chengbei Offshore Oilfield for example, this paper analyzes its cementation and completion scheme and technical difficulties, site preparation and construction situation. The superior cementing quality marks the successful application of ShelfR rotating liner cementing technology in Chengbei Oil Field.
