Abstract: TThe chemical flooding project is characterized for high investment and high risks. To avoid inefficiency of investment, Liaohe Oilfield adopted an evaluation and management system for such a project in its full service life period – from launch of the project to large-scale execution of the project, thus stepping up management of the project. The department of chemical flooding project was launched with clarification of the responsibilities, rights and interests. The efforts were focused on establishment of the evaluation and management system of the full service life period as well as the all-around appraising technology at a multiple of levels and from a multiple of angles, optimization of development plans, enhancement of risks management, and implementation of full-process fine management. Various economic evaluation methods were used in the three stages of project – authentication, operation and appraisal after completion – so that the comprehensive economic performance can be objectively on display. Management was optimized on the basis of the appraising results, significantly reducing the risks for investment. With execution of this project, the enterprise substantially improved its management level, boosting its daily oil production to 351 tons from 63 tons and reducing the water cut to 82.7 percent from 96.7 percent. The oil and gas outputs were increased cumulatively by 22.56×104t and 986.83×104m3 in three years while the sales income was increased by 1.13 billion yuan. The project generated a turnover of 310 million yuan directly and 101 million yuan indirectly, achieving a good social and economic performance.

摘要： 化学驱项目具有投资大、风险高的特点，为了避免无效投入，辽河油田从项目立项到规模实施的全过程， 以全生命周期效益评价为手段，强化完整项目管理。成立责权利相统一的化学驱项目部，明确责任主体，创建全生命 周期评价与管理体系、多层次多角度的全方位评价技术，优化开发方案，强化风险管理，实施全过程精细管理，在项 目论证、运行、竣工后评价3 个阶段分别采取有无对比、跟踪对比、前后对比等不同的经济评价方法，客观展示化学 驱项目的综合效益，根据评价结果进行优化管理，极大地降低了投入风险。项目实施后，企业管理水平大幅提升，日 产油由63t 上升至351t，含水由96.7% 下降至82.7%。3 年实现增油22.56×104t、增气986.83×104m3，增加销售收入 11.3 亿元，项目直接创效3.1 亿元、间接效益1.01 亿元，取得良好的社会效益和经济效益。
