摘要
油田开发综合评价法可应用于不同类型油藏开发效果评价、同油藏多开发方案优选、水平井开发效果评价、油田开发规划等多个领域,但应用于项目后评价的较少。项目后评价是项目生命周期最后和不可或缺的环节,原来进行项目后评价的方法操作繁杂,计算量大,实施有一定困难。综合评价法应用于油田二次开发项目后评价,关键是确定既满足项目后评价要求,又符合实现项目目标的评价指标体系和权重系数,并对可持续性进行后评价及成功度计算。综合评价法是多种评价法与成功度评价法的结合。以油田二次开发项目中的高尚堡油田高5断块沙三段2+3油藏为例,应用综合评价法进行项目后评价,研究表明该区块二次开发方案实施后总体上完成度为79.57%,属基本完成。综合评价法具有简便可靠、可对比性强、客观性强和可操作性强等特点,便于油田二次开发项目后评价的推广应用。
The post evaluation is the last and indispensable procedure of the project life cycle,but the operation of the method is too complex and needs heavy computation,so it is difficult for implementation.The key to the method for the comprehensive assessment for the post evaluation of the project is to establish a system that both meets the requirement of the post evaluation on the project and provides the evaluation index and weight coefficient for the project objective.Also,the post evaluation of the sustainability and the degree of success can be conducted by the system.The method was discussed by integrating combination evaluation method with the success degree method and modifying and taking the secondary development project as the case.The method is characterized of simple,reliable,comparable,objective and operable.The simple method can be applied to the non-detail post evaluation and it is easy to be popularized and applied.
