摘要
应用模糊评判法，在对延吉盆地石油地质基本特征分析的基础上，选取地质、物化探多年数，利用对各参数的权重分配进行调整，确定最佳分配方法，对盆地各区块大拉子组合油气性进行综合评判，其结果验证了目前钻井的情况，进而预测了下一步钻探的有利区块。
By means of fuzzy identification technigue taking yanji basin aii example,this paper demonstrates the application of a method of optimized distribution of theweighted distribution of multiple parameters selectdze from geologocal,geophysical andgeochemical parameters on the composite evaluation of various bIocks of the LowerCretaceous Dalazi formation. Results show the agreement with those data obtained fromexploratory well.A Prediction of three favorable geologocal blocks forhrtherexploratory and drilling is given in this paper.
