模糊综合评价法在火山岩气藏产能建设项目经济效益
综合后评价中的应用戴想
摘要:针对火山岩气巅开发建设项目授资规模大、市场风险高的特点,为确保项目决策科学合理、资金投入得以实现预期收益、技术经济指标达到要求、项目具有良好的生命力和风险抵抗能力,需要对火山岩气藏产能建设项目进行科学合理的经济评价。在火山岩气巅产能建设项目经济效益后评价相关理论的基础上,由专家对经济效益后评价指标进行评估,通过层次分析法明确指标权重,运用模糊综合评价法完成实例研完,应用“最大求属度”
原则得出评价结果,
该方法为火山岩气藏产能建设项目经济效益后评价提供了有效的手段。

Application oftheFuzzy Comprehensive Evaluation Method on Economic Benefit Compre-hensive PostEvaluation ofthe Volcanic Gas Reservoir Productivity Construction Project Dai Xiang
Abstract: Volcanic gas reservoir development and construction projects have characteristics of large investment scale and high market risk. In order to ensure that project decisionmaking can be scientific and reasonable, investment can achieve the expected benefits, technical and economic indicators can meet requirements and the project can have good vitality and ability to resist risks, scientific and reason able economic evaluation should be conducted to the volcanic gas reservoir productivity construction
project.
On the basis of relevant theories about economic benefit post evaluation of the volcanic gas
reservoir productivity construction project,
experts are asked to evaluate the indicators of economic
benefit post evaluation, clarity the indicator weigh through analytic hierarchy process, complete case study by the fuzzy comprehensive evaluation method and get results by applying the principle of maxi-mum membership degree. The method provides effective means for economic benefit post evaluation of the volcanic gas reservoir productivity construction project.
Key words: volcanic gds reservoir; economic benefit; post evaluation; fuzzy comprehensive evaluation
火山岩气藏地质条件复杂,具有储层岩性差、岩相空间变化剧烈、受控因素多1-2、地层埋藏深度大、地温高、成岩作用强,以及气井稳产能力差、气井出水、含二氧化碳的特点,因此,火山岩气藏开发技术方案确定难,钻采工程技术、地面建设难度大,从而造成火山岩气藏开发建设项目市场风险高。火山岩气藏气井单井投资高(高达儿千万元基至上亿元),每个区块都是独立的投资项目,建设井数最少也有十几口。由于火山岩气藏开发工作的高风险性和高投人性,所以必须确保相关工作的科学严谨性、程序的严密性和经济评价的必要性。经济效益后评价能够总结成功的工作经验并吸取教

训,不断提高项目后续运营水平,可为其他同类型项目提供借鉴,而且还能够根据实际经济情况对现行管理方案进行修订,以此不断提高项目管理水平和决策水平,建立一套全面、科学、合理的经济效益后评价研究体系是提高火山岩气藏产能建设项目投资决策管理水平的重要过程。
经济效益后评价内容与作用
经济效益后评价主要包括投资评价、成本评价和效益评价三部分-4。经济效益后评价不仅能够对之前选取评价参数的合理性、工程造价的准确性效益风险控制活动的有效性以及成本分析的科学性
