Trong giai đoạn khai thác thứ cấp này, gaslift là phương pháp khai thác được áp dụng phổ biến. Thực tế cho thấy, khai thác dầu bằng bằng phương pháp Gaslift có nhiều ưu điểm so với các phương pháp cơ học khác được áp dụng tại mỏ Ruby. Hệ thống cung cấp và dẫn khí gaslift là một trong những yếu tố quan trọng và thiết thực đối với điều kiện khai thác thực tế tại giàn Pearl thuộc mỏ Ruby. | Journal of Mining and Earth Sciences Vol. 62 Issue 3a 2021 10 - 16 10 Research on the method of repairing gas lift pipeline from FPSO Ruby - II to Pearl wellhead platform Chuyen Viet Do 1 Thinh Van Nguyen 2 Dung Anh Hoang 2 1 PetroVietnam Exploration Production Corporation Vietnam 2 Faculty of Oil and Gas Hanoi University of Mining and Geology Vietnam ARTICLE INFO ABSTRACT Article history Some offshore oilfields of Vietnam such as Bach Ho Rong Dai Hung Received 15th Jan. 2021 Ruby are at this moment in the secondary recovery stage. Gas lift Accepted 16th May 2021 production is one of the suitable methods in this period. Gas lift has proved Available online 10th July 2021 itself as a more advantageous method in comparisons with other Keywords mechanical methods applied at Ruby oilfield. On the Pearl wellhead Gaslift production methods platform located in Ruby field a gas lift system is installed to serve for the extraction of petroleum. The system is provided with compressed gas Gathering and transportation supplied from the FPSO Ruby II through a subsea 6 inches pipeline gas lift. Subsea pipeline. For the sake of effective producing activity it is a vital task to ensure the safety of this pipeline system during operations. In the case of failures reparation should be applied immediately to minimize shutdown time and reduce the cost of troubleshooting. This article presents the smart flange technique to repair the gas lift pipeline system from the FPSO Ruby - II to the Pearl wellhead platform. Results of the work provide realistic knowledge to propose practical solutions to the maintenance and reparation of this system and thus improve its operation.
