摘要
随着油气田生产的不断发展,各类油气田项目后评价工作的开展也不断深入。为了使后评价工作的评分结果更具科学性与指导性,利用专家调查法和层次分析法(AHP),结合现有的项目后评价评分表,重新确定了项目后评价指标的权重,并采用模糊综合评价法,在中国石油大港油田公司进行实证应用,通过相关实用性分析,探究科学合理的后评价评分方法。研究结果表明:①模糊综合评价法在原有的专家主观打分的基础上对评分数据进行了处理,使油气田项目后评价的评分更加客观、更加科学;②通过模糊综合评价法的运用,能够更直观的反映项目评价各个指标的评分数据,有利于对项目运行各方面进行综合评估;③模糊综合评价法更具灵活性,能满足后评价的需要;④在未来,可将模糊综合评价与数字化结合,运用数据库,建立更加完善的评价指标体系,使得评价指标体系的选取更加自由、多样,同时利用软件对评价数据进行分析,在对项目进行评分的同时,评价的结论也可以随之完成,在数据层面使得评价结果更加客观。
With a continuous field development,some post evaluation on various oil and gasfield projects is carried out without interruption.In order to ensure the scoring results of post evaluation more scientific and instructive,the weights of post-evaluation indexes were redetermined by means of expert investigation method and analytical hierarchy process(AHP),combined with existing project post-evaluation scoring table.Then,one method of fuzzy comprehensive evaluation was practically applied to PetroChina Dagang Oilfield Company for verification.Finally,a way of reasonable post-evaluation scoring was explored on the basis of related practicability analysis.Results show that(1)the fuzzy comprehensive evaluation method processes scoring data on the basis of original expert's subjective scoring,which makes the post-evaluation scoring of oil and gasfield projects more objective and scientific;(2)it can reflect the scoring data of each project evaluation index directly,which is favorable to comprehensively evaluate project operation from different aspects;(3)it is more flexible and can satisfy the need of post evaluation;and(4)in the future,this method can be combined with digitalization.One more complete evaluation index system can established by using database,so that to select the evaluation index system is more flexible and diverse.Meanwhile,evaluation data is analyzed by using software,so that the evaluation conclusion can be reached while the project is scored.As a result,the evaluation results are more objective in the data level.
