| 摘 要： | 充分考虑火山岩地层流体的交互性及模糊性特征,从模糊概率理论出发,应用测井解释基本原理,对选取的火山岩样本层位测井数据进行综合统计;借助离差平方和的概念,构建地层流体的模糊概率识别功能函数;应用模糊数学及统计理论方法,确定模糊概率的概率密度函数和隶属函数;在此基础上建立基于模糊概率理论的松辽盆地火山岩地层流体识别数学模型.实例计算的识别准确率在80%以上,表明该方法切实可行,具有推广应用的价值. |

| Abstract: | The interactivity and ambiguity of volcanic fluid were adequately considered. Based on fuzzy probability theory and log interpretation axiom,sampled data of volcanics were selected and cluster analyzed. A fuzzy probability function for fluid identification was established by using the conception of sum of squares of deviations. The probability density function and subordinate functions were established by using the theory of fuzzy mathematics and probability. And a mathematical model used for formation flui... |
