摘要:

天然气水合物藏的开发具有高风险、高难度和高投入的典型特征,正确评价开发品质是天然气水合物藏开发的前提和关键性问题。针对天然气水合物藏开发评价指标的广泛性和评价结果的模糊性特征,选择天然气水合物藏开发品质的主控因素为因素集,建立主控因素的评分准则,利用层次分析法确定主控因素的综合权重并建立权重集,进而完成天然气水合物藏开发品质的模糊综合评价。利用该方法对麦索亚哈(Messoyakha)天然气水合物藏和其他典型天然气水合物藏的开发品质进行评价,验证方法的适用性和可行性,以期为天然气水合物藏的高效开发提供理论基础和技术支撑。

Abstract:

The development of the natural gas hydrate reservoirs has the typical characteristics of high risk, high difficulty and high investment, so the correct evaluation of development quality is a prerequisite and the key to the issue. In order to solve the problems that the evaluation index has limitations and the evaluation results has ambiguity for the development of the natural gas hydrate reservoirs, the factor set is chosen based on the main controlling factors, and the scoring criteria of main controlling factors are defined. The weight set is established by the comprehensive weight calculated by analytic hierarchy process, and then fuzzy comprehensive evaluation of development quality of natural gas hydrate reservoir is further completed. This method is used to evaluate the development quality of Messoyakha and other typical natural gas hydrate reservoirs, and the applicability and feasibility of the method are verified, so as to provide theoretical basis and technical support for the efficient development of the natural gas hydrate reservoirs.

Key words: natural gas hydrate, development quality, fuzzy comprehensive evaluation, qualitative evaluation, analytic hierarchy process
