气井产能的模糊综合评价

Fuzzy Synthetic Evaluation of Gas Well Productivity

气井产能作为一个表示动态特征的参数，是气井评价的重要指标之一。依据测井数据进行产能评价，采用模糊数学中的模糊多目标决策综合评判建立了气井产能评价模型。对已分好类的气井建立贝叶斯判别函数，对其进行回判，并且通过实例进行验证，为气井产能评价方案提供了理论依据。

As a parameter representing the dynamic characteristic, gas well reservoir performance is one of main indices for gas well evaluation. Rely on the well-logging data, the prediction system using the many targets to make a strategic decision of the fuzzy math has been established. And make the Bayes＇ discretion function for the divided gas well to make the well return judge, thereby calculate the right judge＇ probability. The successful prediction examples confirm the validity of the methods.
