Abstract: The reliability, economy and adaptability of offshore oil and gas field development offshore are determined by the rational offshore development. Based on the evaluation model of single index, the weight of each index and rating grades are established by the fuzzy analytic hierarchy process. Then, the comprehensive evaluation model that considers reliability, adaptability and economy of offshore oil and gas fields is proposed, in order to evaluate and optimize the engineering model of offshore fields, which is essential to develop offshore field economically and reasonably. The results shows that the model is more comprehensive objective and effective, which could avoid the defects of single index evaluation and provide a more systematic evaluation method for the optimization of offshore engineering modle.

摘要： 海上油气田的合理开发决定海上油气田开采的可靠性、经济性、适应性。在参考现有单个指标评价研究的基础之上,通过模糊层次分析法制定评分等级标准,确定评价指标权重,建立以可靠性、适应性、经济性为三个主要指标的海上油气田工程模式综合评价模型,以定量评价优选海上区块最佳的工程模式方案,以期有助于经济合理开发海上油气田。结果表明,该模型评价更加全面、客观,有效地避免了单一指标评价不全面的缺陷,为海上工程模式优选提供了一种更加系统的评价方法。
