Application Research of Engineering Construction Standardisation in an Oilfield Development Adjusting Project in Bohai Sea

In order to improve the efficiency and economic benefits of oilfield development, the researchers applied the standardisation achievements of Bohai oilfield engineering construction in the preliminary research and basic design of an oilfield development adjusting project in Bohai Sea for the first time. The application research mainly contains the topside, jacket, living quarter and workover rig of the project. In which, the topside and jacket are researched based on the standardisation achievements of Eight-Legged Central Platform Type B, the living quarter applies the standardised 60 persons living quarter and the workover rig adopts the achievements of workover rig HJX180D. Meanwhile, some optimizations and adjustments are carried out according to the actual needs. Through the application research, the basic design of the new platform is basically consistent with the standardised platform, and some settings are optimized and adjusted. Then the comparison and differences of the settings are analyzed between the two platforms, and the improvement measures are proposed for better application of standardisation achievements. Through the full application research of the standardisation achievements of Bohai oilfield engineering construction, the project is conducive to the improvement of the efficiency and quality in management, research design, procurement and platform construction. As a result, it can save the construction period and cost, and improve the overall economic benefits of the oilfield development. Through the application of the standardised drawings and documents of the standardised topside, jacket, living quarter, workover rig and main equipment, the design period is shortened by 3 months comparing with the conventional period. Moreover, the standardised design of the main structural materials and equipment not only can save the procurement time and reduce cost, but also can facilitate the process management of the equipment and materials. Therefore, the economic benefits of the oilfield are effectively improved, which can provide strong support for the smooth production of the oilfield. The experience accumulated in the application research of standardisation achievements in this project can provide some reference value for the promotion and application of similar projects in the future.
