Abstract: There are a series of problems existing in offshore oil and gas development, such as marginal field development, low production and economic benefits, scattering locations, tight project schedules, multiple interfaces, inadequate basis for design and complicated engineering plan. Therefore, this paper comes up with the management pattern of regional development integration project and explains the organizational system and obligations of regional development project management. The management conception is defined as “independent unified technology and unified interfaces in parallel.” It also puts forth the unified the method for unified regional development technology, namely unified plan for regional oil and gas treatment center, unified plan for regional oil and gas destinations, unified plan for regional power supply and control, unified pattern for appraisal of regional projects, unified plan for regional engineering and geological surveying and unified plan for regional construction resources. In addition, the study is independently made in four areas – functions of each project platform, drilling and completion plan for gas fields, estimation of investment for a project, and offshore installation plan. Efficiency is improved by means of regional management while technology is optimized by means of unified plans. As a result, the economic performance of regional oil and gas field development is improved, further tapping the potential of the whole regional oil and gas resources

摘要： 针对海洋油气区域开发中油气田多但产量规模小、位置分散、单一油气田开发经济效益差，项目工期紧张、 涉及界面多、设计基础不充分、工程方案复杂等问题，提出了区域开发集成项目管理模式，阐释了区域开发项目管理 组织体系和职责界定，以及“技术统筹、相对独立、界面统筹、平行推进”的管理理念，提出了“六个统筹、四个独立” 的区域开发技术统筹方法，即：统筹规划区域油气处理中心、统筹规划区域油气流向、统筹规划区域供电及控制方案、 统筹考虑区域项目评价模式、统筹实施区域工程地质勘察、统筹考虑区域施工资源6 个统筹；独立开展各项目平台功 能研究、独立开展气田钻完井方案研究、独立开展各项目投资估算研究、独立开展海上安装方案研究4 个独立。通过 区域管理促效率、技术统筹促优化，提高了区域油气田开发经济效益，盘活了整个区域连片的油气资源。
