摘要
应用突变理论和模糊数学相结合的方法产生突变模糊隶属函数,并由此建立稠油油藏优先开发排序模型。该模型首先建立稠油油藏指标体系结构,并对油藏参数进行归一化处理;然后应用突变模糊隶属函数法,对稠油油藏进行综合评价。评价值高的稠油油藏可优先动用。应用该模型对我国11个已开发稠油区块进行实例验证。验证结果表明,模型评价结果与这些区块的实际开发效果吻合较好,说明该排序模型对稠油区块开发动用的决策具有一定的指导意义。该模型避免了模糊评价法、因子分析法及层次分析等方法的弱点,减少主观性又不失科学合理性,对稠油油藏开采具有应用价值。
A new assessment method combined catastrophe theory and fuzzy mathematics is established and applied for the first time to determine the development sequence of heavy oil reservoirs, in which subordinate functions of reservoir parameters are derived with the combination of catastrophe theory and fuzzy mathematics. Based on these subordinate functions, comprehensive values of all heavy oil reservoirs are calculated, based on which, the development sequence of all reservoirs is ranked. The greater the evaluation value is, the more prior the development sequence of the reservoir is. Finally, 11 developed heavy oil reservoirs are presented to validate the ranking method. Result shows that the sequence ranked by the method is in accord with the order of benefit very well. The method can ensure the veracity and creditability of the evaluated result and avoid the randomicity and troubling of hierarchy process, factor analysis, fuzzy comprehensive appraisal and other assessment methods. The ranking method has been proved to be practical in the decision of heavy oil development.
